What Does P1608 Mean?
The PCM is receiving faulty or missing steering angle data from the steering angle sensor. This affects stability control, power steering assist, and other chassis control systems that rely on steering input.
Common Causes
40%
Steering angle sensor requires calibration after alignment or battery disconnect
30%
Failed steering angle sensor in steering column
20%
CAN bus communication error between steering sensor and PCM
10%
Damaged clock spring or connector in steering column
Diagnostic Steps
1
Step 1: Perform steering angle sensor calibration/reset procedure using scan tool with wheels straight
2
Step 2: Monitor steering angle sensor data while turning wheel lock-to-lock, verify smooth signal change
3
Step 3: Check for additional DTCs in ABS, stability control, and power steering modules
4
Step 4: Inspect clock spring connector and wiring for damage or intermittent connections
5
Step 5: Test CAN bus signals at steering column connector for proper voltage and communication
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
The PCM is receiving faulty or missing steering angle data from the steering angle sensor. This affects stability control, power steering assist, and other chassis control systems that rely on steering input.
The most common cause of P1608 (Steering angle signal Error message from steering angle sensor) is: Steering angle sensor requires calibration after alignment or battery disconnect
Typical repair costs for P1608 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Electronic stability control and traction control may be disabled. Power steering assist may be affected, reducing vehicle safety during emergency maneuvers.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1608 to identify the root cause.
