Clutch Switch: Description and Operation
Clutch pedal sensor (manual transmissions only)
The clutch pedal sensor provides the Engine Control Module (ECM) with information about the position of the clutch pedal.
This information is used by the control module to switch off the cruise control.
The sensor signal is also used by the control module to prevent engine start if the clutch pedal is not pressed (certain markets).
The sensor consists of a sliding potentiometer which is supplied with power by the control module (signal) and which is grounded in the control module.
The resistance in the sensor drops when the clutch pedal is pressed.
The Engine Control Module (ECM) can diagnose the clutch pedal sensor. The status of the switch can be read using VIDA.
The sensor is on the pedal box by the clutch pedal.
