Normal Operation
WARNING: This page is about a different car, the 2004 Mercury Mountaineer and 2004 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The steering position sensor monitors the steering wheel position when the toothed-wheel on the steering shaft passes through its magnetic field.
Steering wheel rotation (in degrees) is sent to the ABS module through circuit 1572 (DG) and circuit 1573 (YE). Voltage is supplied by the ABS module through circuit 1576 (TN/BK) which is spliced to circuit 1003 (GY/YE). Ground is provided by the ABS module through circuit 1577 (BK).
Possible Causes
- circuit 1003 (GY/YE) open or short to ground
- circuit 1572 (DG) open, short to ground or short to power
- circuit 1573 (YE) open, short to ground or short to power
- circuit 1576 (TN/BK) open or short to ground
- circuit 1577 (BK) open, short to ground or short to power
- steering position sensor (part of the clockspring)
