Idle Validation Switch





Idle Validation Switch
The ECT Switch portion verities when the accelerator pedal is in the idle position. This switch protects against in-range failure of the ETC sensor.

A PCM detected fault of the ETC Switch will illuminate the Malfunction Indicator Lamp. An inoperative ETC Switch detected by the PCM will only allow the engine to run at idle.
