Invalid Data Received from Steering Angle Sensor
The steering angle sensor is sending bad data to the control module.
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 steering angle sensor measures how far and in which direction you're turning the steering wheel. If it gives faulty readings, the system can't adjust things like traction control properly.
What the computer is actually seeing
The control module expects a specific voltage range from the steering angle sensor, usually between 0.5 to 4.5 volts, corresponding to the angle of the steering wheel. If it sees values outside this range, it triggers a fault.
What a healthy reading looks like
Steering angle sensor should show a voltage from 0.5V (full left) to 4.5V (full right) with 2.5V being center.
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.
- 11. Inspect the wiring and connectors for the steering angle sensor. Look for corrosion or loose connections. If the wiring or connectors are damaged, repair or replace as necessary. Decision: If wiring/connectors are good, move to step 2; if damaged, fix and retest.
- 22. Using a scan tool, check the live data from the steering angle sensor. Look for voltage readings. If the values are sporadic or outside the expected range, the sensor may be faulty. Decision: If readings are bad, replace the steering angle sensor; if readings are good, move to step 3.
- 33. Verify the control module is functioning properly. Check for any additional codes that may indicate other problems. Decision: If there are other codes related to the control module, it may need to be repaired or replaced; if no other codes present, consider the possibility of a software update or reprogramming.
