Whats this...?

What's a TPS?

I can't put bake on the floor...


Have a problem starting motor after replacing...


The TPS (Throttle Position Sensor) is part of the sensor mechanisms that make available your car's engine computer (ECU) all the info it needs on the engine so it can modify the fuel, timing, etc. to trade name it run properly and reduce emmissions as you drive. There are a whole series of inputs that flow into the computer including the throttle positon, intake heat, crank positon, oxygen in exhaust, etc.

It is not unusual for the TPS to need to be familiar or replaced and that may be why you are asking the question.


This is sometimes confused with the TPMS which is the tire pressure monitoring system required on adjectives 2008 cars in the US.
