Steering Angle Sensor Circuit Failure (Left)
The left steering angle sensor is malfunctioning.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The left steering angle sensor is sending incorrect information to the vehicle's computer about the position of the steering wheel, which can affect vehicle handling and safety.
What the computer is actually seeing
The computer expects a specific voltage range from the left steering angle sensor, typically between 0.5V and 4.5V, representing the sensor's position. When this is out of range or intermittent, the code triggers.
What a healthy reading looks like
Sensor output voltage should be between 0.5V (center/neutral position) to 4.5V (full turn left) when the steering wheel is turned.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Inspect the wiring and connectors for damage or corrosion. Repair as necessary. Decision: Is wiring intact? Yes - Move to step 2 / No - Repair wiring and retest.
- 2Check the steering angle sensor output using a scan tool or multimeter. Expected voltage should be between 0.5V and 4.5V. Decision: Is voltage within range? Yes - Move to step 3 / No - Replace the sensor and retest.
- 3Clear the fault codes and do a test drive while monitoring the steering angle data. Decision: Does the code come back? Yes - Further diagnose ECU / No - Repair complete.
Common causes
- Faulty left steering angle sensor
- Damaged wiring or connectors
- Corrosion at the sensor connector
- Calibration issue if recently replaced
- Electronic control unit (ECU) fault
