Clutch pedal sensor (manual transmissions only)
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
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 reduces as pressure increases on the clutch pedal.
The engine control module (ECM) can diagnose the clutch pedal sensor. The status (position) of the sensor can be read using VIDA.
The sensor is on the pedal box by the clutch pedal.
