The Clutch Release Switch may be misadjusted.
• | The lower switch, the Clutch Pedal Position (CPP) Switch provides feedback to the PCM that the clutch pedal has been depressed to enable starting. The CPP Switch DOES NOT relate to the P0883 code. |
• | The upper switch, the Clutch Release Switch also referred to in SI as the Clutch Cruise Control Release Switch, provides the PCM feedback as to the position of the clutch pedal. |
• | Refer to Manual Transmission Component Views, Figure 2: 01 Y-Car: Comp Loc Views (Under LH Side of the Dash) SI Document ID # 714735 for switch locations. |
Important: Multiple clutch presses during a single stop may provide inaccurate feedback to the PCM and the technician may misdiagnose the need to replace the PCM. The Tech 2® may not pick up the multiple presses which would appear that the PCM is not picking up the signal. The PCM should not be replaced if the Tech 2® does not pick up multiple clutch cycles during testing.
For additional information of DTC P0833, refer to SI Document ID # 1394327.
