Code C0608 indicates that the Steering Wheel Angle Sensor (SAS) is providing a signal that falls outside the expected performance parameters. This means the vehicle's stability control system cannot accurately determine the steering wheel's position, often resulting in disabled traction or stability control functions.
The internal electronics of the sensor itself can degrade or fail, causing erratic, stuck, or out-of-range signals to the control module.
Corroded, chafed, or disconnected wiring and connectors between the sensor and the control module can disrupt the signal circuit.
A damaged clock spring in the steering column can interrupt the electrical connection to the angle sensor.
The sensor may have lost its zero-point calibration, often due to battery disconnects or steering component replacements, requiring a reset.
A failure in the ABS or body control module that processes the sensor signal could cause this code, though this is highly uncommon.
The vehicle is generally drivable, but the traction and stability control systems will be disabled, reducing safety in emergency maneuvers.
No, replacing the PCM or ABS module is almost never the correct fix for C0608. The issue is overwhelmingly caused by a faulty sensor, wiring, or a need for recalibration, rather than the control module.
Disconnecting the battery can sometimes cause the steering angle sensor to lose its zero-point calibration. A recalibration with a compatible scan tool is usually required to clear the code.
While some older vehicles allow a manual calibration by turning the steering wheel lock-to-lock, most modern vehicles require a bidirectional scan tool to properly recalibrate the sensor and clear the code.
