Normal Operation
WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The clutch pedal position (CPP) switch, normally closed, supplies a ground signal through circuit 306 (TN/LB) for the powertrain control module (PCM) when the clutch pedal is disengaged. When the clutch is engaged the ground is removed and the speed control is deactivated. Ground for the CPP is supplied by circuit 570 (BK/WH).
Possible Causes
- Circuit 306 (TN/LB) open, short to ground
- Circuit 570 (BK/WH) open
- CPP switch
- PCM
