Clutch position sensor circuit

P0806 Clutch position sensor circuit range/performance
P0807 Clutch position sensor circuit low
P0808 Clutch position sensor circuit high
Description
The clutch position sensor is used to identify the position of the clutch (engaged, disengaged or slipping). This
information is used to control features such as fuel cut during gear changes, cruise control deactivation and
ensuring any torque increase requests from the ESP system only occur with the clutch engaged.
The ECM continuously monitors the clutch position sensor input for malfunctions.
