What is a throttle pedal position sensor switch?
On an Electronic Throttle Control (ETC) system, the PCM keeps track of throttle plate position and uses input from two or in rare cases, three throttle position (TP) sensors mounted on the throttle body and a pair of accelerator pedal position (APP) sensors connected to the accelerator pedal.
Where is the pedal position sensor located?
The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used.
How do you know when your throttle position sensor is bad?
Your engine might stall, idle slowly or misfire when your car is stopped. The car might accelerate itself, hesitate to accelerate, or lack power when you are trying to accelerate. You may also experience difficulty in changing gears.
