Action in service
Check the following potential fault causes and repair as
needed:
1. The signal wire between the sensor and the control
module is open or shorted to positive or ground.
2. Open circuit in voltage supply or ground wire.
3. Open circuit in one or both signal wires between sensor
and control module.
4. If the sensor is a passive sensor (inductive sensor) the gap
