How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my throttle position sensor replacement and how much do those parts cost?

You can check your owner’s manual or ask your mechanic for precise parts, but here are the main things you’ll need:
  1. Throttle position sensor: This is the main component that needs to be replaced. A throttle position sensor is an engine sensor used to track the airflow entering the engine. On its own, a new throttle position sensor can range anywhere from $25 to $150.
  2. Throttle plate: A throttle plate is a valve that regulates the amount of vaporized fuel that enters your car engine’s cylinders. Although you might not need to replace this part with the throttle position sensor, it's a good idea to get your mechanic to inspect it, especially if you have an older vehicle. In the case that it also needs replacement, throttle plates normally cost between $30 to $175. 
  3. Throttle body: The throttle body regulates the flow of air and fuel into your car's cylinders. If your mechanic determines that it also needs replacement, a new throttle body can cost anywhere from $100 to $1000.
  4. Throttle body gasket: Made of paper or aluminum, the throttle body gasket sits between the throttle body and intake manifold and ensures an airtight seal to prevent air bypass. It’s often replaced during throttle body service, and usually goes for $5 to $25.
You can purchase throttle position sensor parts for your car from auto parts stores like AutoZone, NAPA Auto Parts, and Advance Auto Parts, as well as online retailers such as Amazon and RockAuto. Three of our recommended brands for throttle position sensor parts are ACDelco, Standard Motor Products, and Beck Arnley. For throttle plates and throttle bodies, we recommend brands like Dorman, ACDelco, and Cardone provide, and for throttle body gaskets, Fel-Pro, Mahle, and Victor Reinz. With this said, the best parts and brands for your throttle position sensor will vary based on your vehicle’s year, make, and model.
Although both OEM and aftermarket throttle position sensors have their benefits and tend to be reliable, OEMs usually provide more longevity than their more cost-effective aftermarket counterparts.
You can purchase throttle position sensors at body shops and auto parts shops like AutoZone, NAPA Auto Parts, and Advance Auto Parts, as well as through online retailers like Amazon and RockAuto.
Tip: It’s best to first check your owner’s manual to confirm that the parts you’re purchasing are compatible with your vehicle.

How will a mechanic replace my throttle position sensor?

For this service, your mechanic will test the throttle position sensor to verify it has failed and replace it with a new one. When replacing your TPS, your mechanic will typically follow these steps: 
  • Scan the car’s computer system for error codes
  • Pop the hood to inspect the throttle plate and the surrounding area
  • Test the throttle position sensor and related wiring
  • Remove the faulty TPS
  • Install new functioning TPS
  • Clean any carbon buildup from the throttle body
  • Reinstall the throttle body and reset the minimum idle speed to the factory setting
  • Clear any trouble codes from the car’s computer and check for proper operation
  • Drive the car to test for proper gear shifting, speed, and acceleration

What happens if I don’t replace a bad throttle position sensor?

If the sensor fails, the computer cannot calculate how much air is already in the engine and won’t inject the right amount of fuel.
This is a fairly normal problem, but it needs to be taken care of quickly.
You should take your car to the shop for an inspection when you notice any signs of this problem. To run efficiently, your car needs the right ratio of air and fuel. When the throttle position sensor stops working, the engine will not get the right amount of air and will lose power. You may not be able to shift gears, and the car may not even start anymore.

What is a throttle position sensor?

Your car relies on the right fuel-to-air ratio to run properly, and this ratio is managed by the air intake system. The throttle body controls how much air enters the car’s engine through the throttle plate—essentially, the more you push down on the gas pedal, the wider it opens, allowing more air into the engine.
The throttle position sensor (TPS) tells your car’s computer, or engine control unit (ECU), what position the throttle plate is in, and then the computer calculates how much fuel needs to be injected into the air intake system. If the sensor fails, the computer cannot calculate how much air is already in the engine and won’t inject the right amount of fuel.

What are the symptoms of a bad throttle position sensor?

There might be a few symptoms that your speed sensor needs fixing, such as: 
  • Poor engine performance, including engine stalling and misfiring
  • Lack of power
  • Gears stop shifting
  • The check engine light comes on

How often do you need to replace a throttle position sensor?

Throttle position sensors don’t have specific lifespans. While these sensors can last the lifetime of your car, failures start becoming more common once your car’s mileage exceeds 80,000 miles.

Is replacing a throttle position sensor yourself easy?

Although replacing a throttle position sensor isn’t the trickiest project, if you decide to go the solo route, be sure to be confident in your DIY auto repair skills. If you don’t have the right tools and experience, we recommend letting a certified mechanic fix the problem.

FAQs

This service takes around one hour to complete.
You shouldn’t drive with a broken throttle position sensor. When the throttle position sensor stops working, the engine will not get the right amount of air and will lose power, which means the car may not start, and you won’t be able to shift gears if it does.
