Normal Operation
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The speed control actuator sends a voltage reference signal through circuit CET21 (GN/WH). When the clutch is applied, the clutch pedal position (CPP) switch closes and routes the signal to ground through circuit RE407 (YE/VT). Ground is supplied by the PCM.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Obstructions to the accelerator pedal or linkage
- Speed control actuator
- CPP switch
- Speed control cable
- Accelerator cable
- PCM
