Average Cost to Replace a Throttle Position Sensor

All vehicles have something called a “throttle” which controls how much fuel is allowed to flow into the engine. The throttle position sensor is what monitors the throttle position from the shaft. Basically, this sensor is connected to a computer inside the vehicle which shares information sent by the driver. This information contains the actions of the driver such as accelerating, power steering and so forth. So anytime you step on the gas pedal to accelerate your vehicle, the computer sends this information to the sensor so that the throttle knows how much fuel to let flow into the engine. In the old days, there used to be a cable that was connected from the throttle to the accelerator. But now in the technological age, the car’s computer controls when the throttle opens and closes by the feedback it gets about the acceleration of the vehicle.

If you need to have your throttle position sensor replaced, the cost will depend on the type of car you have. But the average cost of this replacement job is not that expensive. The parts will cost you between $75 and $130 on average. The labour costs will be anywhere between $60 and $90, depending on the hourly rate of the mechanics. So in total, you can expect to pay between $135 and $220 for a throttle position sensor replacement. And, of course, there may be taxes and fees added onto these costs which are determined by your location. But it’s still not too expensive when you consider everything else that could go wrong with your car.

Now you may be wondering when you’ll need to have your throttle position replaced. The simple answer is when your computer can no longer detect any signal from the throttle position sensor. The will likely force your computer to stall the engine and only allow it to run at low RPMs, which means the car will only move at slow speeds. This is a safety feature enforced by the computer so that your engine doesn’t get too damaged. A throttle position sensor will generally fail simply from the wear and tear of driving the vehicle for many years. There is nothing you can really do to prevent this sensor from failing because it will just happen on its own. The only thing you should do is have it replaced as soon as you notice these symptoms occurring in your vehicle.
