C0396 Code: Meaning, Causes, and Symptoms | OBD2 Codes

C0396 – Incremental Sensor


C0396 Possible Symptoms


Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)


C0396 Possible Causes


Faulty Incremental Position Sensor (IPS),Incremental Position Sensor (IPS) harness is open or shorted,Incremental Position Sensor (IPS) circuit poor electrical connection


C0396 Description


The transfer case Incremental Position Sensor (IPS) sends current transfer case mode/range position to the Transfer Case Shift Control Module (TCCM). The IPS receives an 8 volt reference signal from the TCCM and sends back a transfer case incremental position signal and an encoder rotational direction signal. The IPS sends this information as voltage signals which are converted to degrees and rotational direction by the TCCM software. If the Incremental Position Sensor parameter falls outside the acceptable value for a given range, the DTC will set. The IPS is an integral part of the transfer case actuator and cannot be replaced independently.
