C05FD4WD/AWD Range Actuator Position Sensor Circuit Low
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- The range actuator position signal sits below the lowest value an intact sensor can deliver. With a sensor powered from a reference supply this usually means the signal line is shorted to ground, the supply is missing or the sensor output has failed low. Fixed diagnostic bands are common for such position inputs; a Honda and Denso patent for a comparable shift range actuator treats any sensor voltage at or below 0.5 V as abnormal. Sensors with PWM output, as in Magna's transfer case design, show the same fault as a duty cycle stuck at the lower limit. GM bulletin PIP5098 points to a corroded ground terminal for the encoder motor channels on Colorado and Canyon. No maker documents C05FD itself; C05FE is the opposite case.
