A Tire Pressure Monitoring System (TPMS) is an electronic system that monitors air pressure in tires. The Subaru TPMS alerts you when it detects low tire pressure so you can maintain safety on the road.
The Tire Pressure Monitoring System (TPMS) monitors the air pressure inside all four of your vehicle’s tires. When one or more of your tires is underinflated, the TPMS alerts you with a dashboard warning light.
The system uses sensors in each wheel that transmit data to your car’s computer. If you see a TPMS warning light, stop as soon as it is safe to do so and check your tire pressure.
What is the Tire Pressure Sensor all about?
There are many reasons why you should regularly check your tire pressure. Under-inflated tires can lead to decreased fuel economy, reduced traction control, and/or a flat tire. The tire pressure monitoring system (TPMS) is designed to alert you when your tires are under-inflated.
This system monitors the air pressure in all four tires and sends a signal to the instrument cluster if any tire’s pressure drops below the recommended level. The signal tells you which tire to check by illuminating a specific light on the instrument panel.
All vehicles with TPMS have a warning light on the dash that will illuminate when one or more of your tires is significantly underinflated.

In parts cost around $100 and
Labor cost $100-110$.
If your Subaru Ascent Tire Pressure Sensor Replacement is not functioning properly, it can cause your dashboard to light up with low tire pressure warning signs. It is important that you address this issue immediately as driving on tires that are not properly inflated can be very dangerous.
The tire pressure sensor replacement cost will be different depending on the make and model of your vehicle. A tire pressure sensor is a small device that fits inside the tire, and it monitors the level of air in the tire.
If you have low tire pressure, your Subaru will likely alert you to this issue. It’s important to get a Subaru tire pressure sensor replacement right away if your tires are low on air.
If your Subaru needs a tire pressure sensor replacement, it can cost between $100 and $250 for an individual sensor, as well as for labor. This repair can take about 30 minutes to complete. If you need all four sensors replaced, the total cost will be more expensive than just one.
Subaru Tire Pressure Sensor Replacement cost
The average cost for a Subaru Ascent Tire Pressure Sensor Replacement is between $293 and $437. Labor costs are estimated between $95 and $120 while parts are priced between $198 and $317. Estimate does not include taxes and fees.
When your Subaru Ascent’s tire pressure light comes on, it means that one or more of your tires is under inflated. This can be caused by a number of things, but the most common cause is the tire pressure sensor itself.
This part is designed to measure air pressure within your tires and send a signal to your car’s computer when the pressure is low. If you’re wondering how much it will cost to replace this part, the answer depends on several factors.
Tire pressure warning systems are a standard feature on all vehicles made since 2007. The system is designed to alert the driver when one or more tires are low, by illuminating a dashboard warning light. It’s critical to keep tires inflated properly for safety and to maximize gas mileage.
There are two types of tire pressure monitoring systems (TPMS). The first system is called direct TPMS. This type of system uses TPMS sensors that are mounted inside each tire and wheel assembly.
As the wheels rotate, the sensors measure the rotational speed of each tire and send that information to an electronic control unit (ECU) in the vehicle.
The ECU then compares that information to determine whether a tire is under-inflated. If a tire is low, the “low tire pressure” warning light illuminates on the dash, letting you know it’s time to check your tire pressures and add air if necessary.
The second type of TPMS is called indirect TPMS. These systems do not use sensors mounted inside each tire and wheel assembly.
Instead, they rely on data from a vehicle’s anti-lock braking system (ABS) to determine whether a tire is low on air. When you start your car, these systems check everything.
types of TPMS
Direct TPMS is the more sophisticated of the two systems. Sensors mounted in each wheel transmit real-time tire pressure information to a computerized receiver in the vehicle every 28 seconds or so.
If tire pressure falls 25 percent below recommended levels, or if one tire loses 25 percent more air than the other three tires, a dashboard warning light is illuminated.
Indirect TPMS is less precise than direct TPMS at monitoring tire pressure. A sensor in each wheel transmits data to the vehicle’s onboard computer any time the vehicle is moving, but it doesn’t monitor actual tire pressures.
Instead, it measures how fast each wheel is rotating relative to the others and determines whether there’s a difference in rotational speed among them — an indication that one or more tires might be undermined.
How much to replace TPMS sensor on a 2013 Subaru WRX?
The cost to replace a TPMS sensor in a 2013 Subaru WRX is $150 to $200. The part itself should cost you between $100 and $150, and the labor costs are between $50 and $60.
The tire pressure monitoring system (TPMS) in your Subaru is a safety feature that monitors the pressure of all four tires and alerts you if the pressure is low. If any of the tires are underinflated by 25 percent or more, you will see this warning light appear on your dashboard.
The TPMS in a 2013 Subaru WRX uses a system of sensors to track each tire’s air pressure. These sensors can fail over time, causing the warning light to illuminate. If this happens, you may need to replace one or more TPMS sensors.
If you’re not sure whether your TPMS needs replacement, visit your local Firestone Complete Auto Care for a free tire pressure check and inspection.
The sensor itself will cost around $60 to $80. It is only a small part, but it requires a lot of work to replace. You have to remove the tire, unbolt the brake shield, and retrain the tire pressure monitor (TPM) system once it is replaced. The total labor cost to replace a TPMS sensor can be between $20 and $150.
While replacing TPMS sensors may seem like an unnecessary expense, it is important that you keep them maintained for safety reasons.
A low-pressure warning light means that there is something wrong with your tires. If you ignore it for too long, your tires could blow out while you are driving at high speeds.
If you are going to replace the tire pressure monitoring system (TPMS), then you will need to purchase new sensors and reset them so they work correctly with your vehicle’s electronic systems. Some vehicles require specialized tools which cost extra money on top of the price of replacement parts.
The average cost for a tire pressure monitor sensor replacement is between $43 and $59. Labor costs are estimated between $35 and $45 while parts are priced between $8 and $14. Estimate does not include taxes and fees.
Note about price: This service is typically done as part of a bigger, more expensive repair, so the estimate you see above may not represent your total cost.
Tire Pressure Monitoring System Sensors (TPMS) are sensors that keep track of your tires’ air pressure. When your tire pressure drops below a set threshold, the warning light illuminates on your dash.
It’s important to maintain proper tire pressure in order to increase fuel economy and extend the life of your tires.
How much does it cost to replace TPMS sensors?
This is a difficult question to answer because the cost of TPMS sensors differ from car to car. There are two types of TPMS sensors: direct and indirect.
A direct sensor transmits information directly to the vehicle’s computer, while an indirect sensor monitors tire pressure by looking at the speed of each wheel.
Subaru vehicles use direct TPMS sensors, which means you need to have a special tool to program them. Because of that, it will likely cost more to replace a sensor in a Subaru than it would in many other vehicles.
The average cost to replace a TPMS sensor is between $50 and $200 per wheel. This can vary greatly depending on your car, but you should expect to pay at least $50 per wheel.
The costs of replacing a TPMS sensor vary by make and model as well as by dealer. On average, however, expect to pay around $200 for parts and labor.
If you have a newer vehicle, it will most likely be equipped with TPMS. Depending on the type and age of your vehicle, you may have direct or indirect sensors. Direct TPMS are electronic devices that attach to each wheel and monitor the amount of air pressure in each tire.
Indirect TPMS utilize the anti-lock brake system to measure wheel speed. While driving, a computer estimates how much air is in each tire based on differences in wheel speed.
There are two types of direct sensors: snap-in and clamp-in. Snap-in sensors screw into the valve stem and are easy to install when replacing valve stems or tires.
Clamp-in sensors clamp around the valve stem and can only be installed by removing the tire from the wheel and placing them inside the tire before installation.
The majority of vehicles on the road today use snap-in TPMS sensors that go inside new tires when they’re installed.
A TPMS system is designed to warn the driver when a tire becomes significantly under-inflated, usually 25% or more.
All vehicles with a gross vehicle weight rating of 10,000 pounds or less manufactured beginning September 1, 2007 must be equipped with a TPMS system.
Frequently Asked Questions
1. How much does it cost to replace 4 TPMS sensors?
The average cost of TPMS sensors is around $95.00 each, depending on the make and model of your vehicle. If you have a flat tire and need to buy a replacement sensor, this can be quite expensive.
However, if you purchase the new sensors yourself and install them yourself, you can save around $50 per sensor.
2. Why are TPMS sensors so expensive?
TPMS sensors are expensive because they contain sophisticated electronics that must be calibrated to work with your vehicle’s computer system. You cannot just replace a broken sensor with another sensor from another vehicle or it will not work properly.
This is why it is always best to buy OEM (original equipment manufacturer) replacement parts, even if they are more expensive.
3. Can I replace just one TPMS sensor?
Yes, you can replace just one TPMS sensor if needed. When replacing just one sensor, you must get the part number from the inside of the old one before removing it or your new one may not work properly.
4. Can AutoZone Check TPMS sensors?
Yes, AutoZone can check TPMS sensors for free. You will need to bring in your car and have someone help you remove the valve stem cap from you can take your vehicle to a mechanic to find out which sensor needs replacing and have them do it right away.
But if you’d rather DIY this repair, read on for some tips and tricks on how to replace TPMS sensors yourself.
The Subaru Impreza has two different TPMS systems: one that uses direct sensors in each wheel and a second indirect system that uses the ABS wheel speed sensors.
In this case, the owner’s manual describes how to reset the system after replacing a tire or rotating them.
TPMS sensors are expensive because of the technology inside them, and the government mandate that makes them necessary for most cars. Replacing one sensor can cost $50-$70, and a full set is almost as much as the tires themselves.
