Rest the Throttle Position Sensor
How to reset throttle Position sensor [Answered]
A throttle position sensor can be reset by disconnecting the negative terminal of your battery. This is a temporary solution and will not have any lasting effects on your vehicle.
The throttle body is an important part of your vehicle’s engine. It’s responsible for regulating the flow of air and fuel into the combustion chamber.
If there are any problems with your throttle body, it will cause a misfire and possibly damage to other parts of your vehicle. To avoid further damage, you’ll want to troubleshoot the problem as soon as possible.
How to reset electronic throttle control manually
Resetting the electronic throttle control is a bit more difficult than simply turning off the ignition.
First, press the accelerator pedal down slowly until it hits the floor. Then press the accelerator pedal down halfway and hold it there for five seconds. Release the pedal slowly when finished.
Next, turn the ignition on and then turn it off and wait for ten seconds. During these ten seconds, be sure the throttle valve is moving by listening for a sound of operation.
If the throttle valve does not move after ten seconds, listen for a ticking noise coming from the idle speed control motor. If you hear no noise, it means that there is no power to the idle speed control motor and it should be replaced.
How to Reset ECU with Scan Tool
The engine control unit (ECU) is the computer that controls the operation of a car’s engine. ECUs are able to monitor many variables about the engine, such as temperature and pressure, and quickly adjust operations to maintain ideal performance levels.
The scan tool monitors the ECU and displays information about the engine, transmission and other relevant vehicle parts on its monitor. Using this information and diagnostic codes stored in memory, technicians can find faults with the vehicle’s operating system, allowing for quick repairs.
When a fault occurs in the ECU, it generates a diagnostic code that you can read using a scan tool. The scan tool will tell you what fault occurred as well as what component or system it relates to.
A mechanic can use this information to locate the faulty part. If a code doesn’t arise from a known problem, it may be necessary to reset the ECU so that new codes can be generated and traced.
In most cases, resetting an ECU involves turning off the car and removing the key or battery cables for several minutes. The length of time required depends on how many times you’ve previously reset it. In some cases, you may need to replace certain parts before clearing diagnostic codes.
Before you disconnect the scan tool from your car, be sure to write down all fault codes the scan tool stored. Take this information to a repair shop to help diagnose and fix problems. Many advanced scan tools can be kept in the car for future use.
To reset the ECM, you will need a scan tool to communicate with the computer. You will then be able to enter the “code” function and clear all current DTCs.
This is a very simple process, but make sure you are working with a qualified technician or mechanic who has experience clearing diagnostic trouble codes. Always follow proper safety precautions when working around fuel.
Once you have completed the repairs, you will need to reset the “Check Engine” light on your dashboard. Most cars with a computerized engine control system have a diagnostic scanner available so you can see error codes and check fuel efficiency.
The scanner plugs into a port on the car’s dashboard and then transfers the error codes onto your computer screen.
Once you have cleared out all of the errors, go back to the scanner and select “Reset ECU.” This will turn off the engine light on your dash once again. You can repeat this process if there is another error code that comes up in your vehicle.
The resetting process can be completed by unplugging the battery from your car for 10 minutes and then plugging it back in or by using a scan tool. The most important thing is to reset the codes before driving it again.
About throttle position sensor (TPS)
The throttle position sensor (TPS) is located on the side of the throttle body. The sensor contains a magnetic disk that sends pulses to the engine control module (ECM) as you turn the key or push the start button to tell it how far open the throttle is.
In order for the car to speed up, the throttle must be opened more, and in order for it to slow down, you must close it. When you are idling at a stop sign, stop light or while waiting in gridlock traffic, your throttle is almost closed so little gas is flowing through your engine.
The computer uses information provided by the TPS to adjust the idle when you release the accelerator pedal to keep your car from stalling.
It also uses this information to determine if all of your engine’s cylinders are receiving enough gas so that they can properly combust fuel and convert it into power.
Troubleshooting a faulty throttle Position Body
If your car is having issues starting or running, there are several things you can do to troubleshoot the problem before paying to have someone diagnose it for you. The first step is to check the basics.
Make sure that your battery cables are clean and connected properly, that there’s enough oil in the crankcase and that you have fuel in your gas tank. If none of these are the problem, move on to some more advanced diagnostic methods.
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module. This will erase all stored codes so you can start fresh when it comes time to diagnose the problem.
With this method, however, you won’t be able to check stored codes with a scan tool unless you hook up a separate power.

What happens if you disconnect throttle position sensor
If your TPS becomes dirty, damaged or damaged, it will send inaccurate readings to your computer which will cause your idle quality and economy to suffer, so even though resetting it may bring temporary relief, replacement is recommended for optimal performance.

How to Apply the throttle position sensor reset in a Toyota
The throttle position sensor (TPS) is a component of the electronic throttle control system on Toyota vehicles. The TPS is part of the engine control system that adjusts fuel delivery to the engine based on driver input.
The throttle position sensor is controlled by a specific procedure when it fails or has problems reading your throttle position. The reset procedure for a Toyota vehicle uses the ignition switch to tell the TPS that the car is off so that it can be recalibrated, ensuring proper throttle operation.
To apply a throttle position sensor reset on a 4-cylinder Toyota, follow these steps:
1. Turn the key to On without cranking the engine. Wait for 30 seconds.
2. Crank the engine and hold it at 1,000 rpm for 10 seconds, then release the accelerator pedal slowly until you reach idle speed. Release the key from On and then turn it to Off.
3. Turn the key back to On without cranking again. Wait for 30 seconds. Repeat this step two more times before turning off the ignition again.
4. Press and hold down both pedals as you crank and start your car to allow air into your exhaust system while you are spinning up your engine before releasing them as they return to their normal positions after starting your car
5. Pull the parking brake. Set your parking brake again, shift the gear lever into Drive and pull out slowly. And Wait 5-10 minutes.
Before attempting any of these procedures, be sure that you have located your trouble code(s). This should allow you to reset the throttle position sensor.

– Honda Odyssey (2000-2004)
The Honda throttle position sensor (TPS) plays an important role in the engine operation. It is a variable resistor connected to a potentiometer that detects the position of the accelerator pedal, which sends a signal to the powertrain control module (PCM) to determine how much fuel to inject into the engine.
How to Apply the throttle position sensor Reset in a ford: conditional step
Step 1: Unhook the negative cable from your battery for a few minutes. This can be found behind the driver side kick panel on your dash board. The reason you need to unhook the battery is that you will be hitting your starter with 12 volts of power and if you don’t, you’re going to have a bad time.
Step 2: Wait for five minutes. This is important because it will allow your throttle body to cool down after all these years of being exposed to heat. If you don’t let this happen, then the sensor might burn up from sitting in hot engine bay air.
Step 3: Remove the fuse for your engine control module (ECM). The ECM is located behind your glove box and it should be labeled. Remove the ECM fuse and wait five more minutes to reset your throttle position sensor. After waiting five more minutes, put your ECM fuse back in and then connect your negative battery cable.

Throttle position sensor problems
Your car has a lot of sensors that help it determine how best to run itself especially when it comes to performance issues and fuel consumption. Think of them as traffic lights along a road – they tell your car which way to go and prevent crashes from happening while also preventing.
Throttle position sensor symptoms
If you have a throttle position sensor problem, it will usually be pretty obvious — poor power, difficulty in shifting, and hard starting conditions are some of the main characteristics.
However, if your engine is misfiring or stumbling, it may be caused by a faulty TPS. If your engine is running rough, try this diagnostic procedure to locate the problem.
- Turn off the ignition and remove the air intake tube from the throttle body.
- Start the engine and feel for vacuum leaks by applying soapy water to all vacuum lines on the throttle body. If you find a leak, tighten or replace the hose.
- Check all wiring connections at the throttle position sensor, ignition coil and spark plug wires, as well as any wiring harnesses that are near the throttle body. Repair or replace any wires that are damaged or show signs of corrosion.
- Clean any deposits from around the base of the throttle butterfly with a wire brush. A buildup here can interfere with proper positioning of the butterfly arm and cause idle problems or hesitation during acceleration.
- Check for loose bolts on all threaded parts and tighten them as necessary. Make sure that fuel injectors and other internal parts are tightened properly and not binding against one another or against the cylinder head and intake manifold.
How do I reset my throttle body idle:
A few small adjustments can be made to fix an irregular idle.
First, you can check your throttle body with a vacuum gauge. If there is no airflow reading, then you may have a vacuum leak in the intake system or even a bad throttle body that needs to be replaced. If there is airflow but the idle speed is still not correct, then you may need to reset the idle by disconnecting the battery.
This will allow you to start the car without using any stored information in the computer, which could be causing an irregular idle problem.
By unplugging the battery for up to five minutes or disconnecting the fuse that runs to your engine control module, you should be able to start over with a proper calibrated idle speed.
Frequently Asked Questions
1. How do I perform the throttle body adaptation reset?
The throttle body adaptation is a setting in your car’s computer that controls the throttle opening. It is controlled by engine temperature and air flow. If the throttle body adaptation setting has been changed because of a malfunction, you will have to reset it to the factory default.
The way to do this is to follow these steps:
1. Turn the ignition switch on.
2. Press the accelerator pedal to the floor until the engine starts, then release the pedal slowly while watching the engine RPMs rise. The throttle position sensor should be fully closed at 0 revolutions per minute (RPM).
3. Once at 0 RPM, press and hold down the gas pedal for ten seconds or more until the RPMs rise above 2200 rpm, then release the gas pedal slowly back to idle. This will cause a bump or hesitation in your vehicle’s acceleration for about 10 seconds as your vehicle learns its new idle position. You can also see this bump if you accelerate from rest after doing this adaptation procedure, or you can even feel it through your seat as it tries to accelerate with no gas applied.
4. Release the key from ON and then start your vehicle again normally.
5. Make sure that your gas pedal moves freely and doesn’t stick due to rust.
2. What does it mean when your Ford throttle position sensor needs reset?
Ford has designed some models with a throttle body adaptation reset. This is performed to update the throttle body’s adaptation values and it may be necessary if a problem is encountered with it.
Half of the current throttle body adaptation process is performed when you start the engine, and you can see this on your odometer. The other half occurs after 10 seconds of driving, and will be completed when you park the vehicle for 30 minutes or more.
3. How do I reset the gas pedal to full throttle?
If your vehicle does not have adaptive throttle control, check to make sure your gas pedal is not stuck or malfunctioning. To do so:
– Apply pressure to the gas pedal while the engine is off
– If the gas pedal feels stuck or doesn’t move when applying pressure, there may be an issue with your accelerator cable or the accelerator pedal position sensor. You may want a mechanic inspect these components for you.
– If there is no issue with the accelerator cable or accelerator pedal position sensor, then there may be an issue with your engine computer module (ECM).
4. When turn on ignition switch adaptive throttle control unit?
When you turn on the ignition switch, the Adaptive Throttle Control Unit (ATCU) is automatically activated and the throttle pedal position is returned to its full-open position.
The system then determines which mode of operation will be used: AT or City. It takes about one second for the ATCU to make this determination.
The system uses various sensors (gas pedal position sensor, coolant temperature sensor, throttle control sensor, etc.) to decide which mode to use. The system also takes into account vehicle speed when making this decision.
When a cold engine is started, the system will be in AT Mode as long as there are no faults detected in any of the sensors or in other components (engine control unit, transmission control unit, etc.).
If a fault is detected during startup, the ATCU will go into Default Mode and operate in AT Mode until the fault is corrected. When a fault is detected, the status indicator lamp will illuminate.
5. How do I reset my electronic throttle body?
The throttle body is controlled by the throttle position sensor (TPS). If you remove the throttle body, the TPS is located on top of the throttle body. There are two methods to resetting a TPS. One method is to disconnect the battery for around 10 seconds.
The second method is to remove the air intake hose from the throttle body, connecting it back once you have reset the TPS.
In order to reset your TPS, we recommend that you consult an auto repair mechanic, such as one from YourMechanic. They will be able to diagnose your start-up issue and make any necessary repairs for you.
6. How do you Apply a throttle position sensor Reset?
The reason your throttle body needs to be reset is because it has a built-in fail safe mechanism that shuts off the throttle if the sensor is not getting any voltage.
Trying to start a car with a dead or faulty throttle position sensor (TPS) may cause the engine to crank over and over for an extended period of time. If you keep trying, eventually you may get lucky and have the engine actually start.
However, even then, the vehicle will run very poorly. The engine may surge and stumble, idle erratically, or not accelerate up to speed. These symptoms can lead you to believe that you have a bad fuel pump, when in fact it is simply a matter of resetting the TPS.
The following steps will show you how to manually bypass your TPS so that you can get your car running normally again.
First, turn off your ignition key and make sure all electrical systems are turned off (radio, lights, etc.). Then remove the negative cable from the battery by loosening the nut on top of it with a wrench or socket set.
Once you have removed this cable, there is no need to wait for any period of time before moving on with this procedure.
7. Does a new throttle body need to be reprogrammed?
The answer to the question is yes. After installing a new throttle body, if you do not reprogram it, you will have problems. The computer must know the size of the throttle body in order to properly control idle speed and fuel/air mixture under acceleration.
The computer also must be told whether you have a drive by wire (electronic throttle) or a conventional mechanical linkage to the throttle cable. High-performance engines may require a special set because of the high flow air filter or other modifications.
8. How to Clean the Throttle Body?
Disconnect the negative battery cable. Remove air intake hose from the throttle body. Spray carburetor cleaner into throttle body (through intake hose) until thoroughly cleaned.
Reinstall air intake hose onto throttle body with clamp tightened down firmly. Reconnect negative battery cable. Start vehicle and let idle for 10 minutes as car warms up. Check Problems After Cleaning Throttle Body.
Start vehicle and let idle for 10 minutes as car warms up so that the electronic throttle can be calibrated to the new throttle body.
