Diagnostic techniques for a clutch interlock switch and a clutch pedal position sensor

A diagnostic method for a clutch pedal position sensor and a clutch interlock switch of a vehicle having an engine with an electronic stop-start (ESS) system and a manual transmission, the method comprising:

• receiving, by a controller and from a clutch pedal position sensor, an output voltage indicative of a level of depression of a clutch pedal that is configured to control engagement and disengagement of a clutch assembly of the manual transmission;
• receiving, by the controller and from a clutch interlock switch, an on/off state indicative of a position of the clutch pedal relative to a fully-depressed position;
• correlating, by the controller, the output voltage of the clutch pedal position sensor and the on/off state of the clutch interlock switch to detect a malfunction of the clutch pedal position sensor or the clutch interlock switch;
• and
• disabling, by the controller, the ESS system when the malfunction of the clutch pedal position sensor or the clutch interlock switch is detected.
