Closed Throttle Position Switch

Closed throttle position switch is located in the Throttle Position (TP) sensor. ECM/PCM senses whether accelerator pedal is depressed or not. High voltage (open) or low voltage (closed) signal is input to ECM/PCM, which then controls Idle Air Control (IAC) motor based on input signal.
