DTC P1705: Throttle Position Sensor: Description: Notes

The throttle position sensor detects the throttle valve position and sends a signal to the TCM.

Consists of a wide open throttle position switch and a closed throttle position switch. The wide open position switch sends a signal to the TCM when the throttle valve is open at least 1/2 of the full throttle position. The closed throttle position switch sends a signal to the TCM when the throttle valve is fully closed.
