Read our answers to questions about throttle position sensor replacement costs, symptoms and more.
What does a throttle potentiometer do?
The throttle potentiometer is the recipient of the signal from the accelerator pedal where vehicles have an electronic pedal (and therefore not a cable operated one)
What does a throttle position sensor replacement involve?
Depending on the manufacturer, a number of different processes will need to be done in order to access the throttle potentiometer, however the mechanic will need to do some of the following basic steps

- Once confirmed that the throttle potentiometer is faulty, they will continue on to replacing it.
- Once replaced, the mechanic will start the engine and recheck the error codes

Can I drive with a bad throttle position sensor?
Driving the vehicle with a bad throttle position sensor will result in poor engine performance and the car may stall. If you suspect there is any issue with your vehicle's throttle position sensor or there are concerns about its condition, book an inspection with a professional mechanic as soon as possible so they can check and advise on next steps.
Is a bad throttle position sensor an MOT failure?
Althought a throttle position sensor (TPS) in itself is not checked during an MOT, a faulty TPS can cause the engine to stall or not start at all which can result in an MOT failure.
What happens when throttle position sensor is bad?
If the throttle position sensor is bad, the engine may start to run at very high RPM because the throttle is stuck open. The engine could eventually overheat and seize up. This could also lead to dangerous situations on the road.
Can I drive without TPS sensor?
It is possible to drive without a properly working TPS sensor, but it is not advisable. The TPS sensor is responsible for monitoring the position of the throttle pedal and relaying that information to the engine control unit. Without this information, the engine may run erratically or may not start at all.

Throttle position sensors are designed to last up to the life of the vehicle, but it is not uncommon to get it replaced at around 100,000 miles.
Does a throttle position sensor need to be programmed?
Yes, a TPS will need to programmed and calibrated to ensure that it is accurately measuring the position of the throttle. If the sensor is not programmed, it may not be able to correctly interpret the throttle's position, which could lead to inaccurate readings.
Can a throttle position sensor be repaired?
Yes, a throttle position sensor can be repaired and some issues can be easily fixed by reprogramming, however, in many cases, it is easier and most cost-effective to get the whole sensor replaced.
