Steering Sensor Range/Performance Problem

The steering sensor measures how much you're turning the steering wheel. If it sees values outside its expected range, it triggers a warning. It's like your speedometer reading 140 mph when you know you're parked.

The computer monitors the steering angle sensor voltage, which should vary between 0.5V (straight) to about 4.5V (full turn). If it detects values outside this range or inconsistent readings, it sets the code.

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.

1. 11. Inspect the wiring and connectors for damage or corrosion. Repair as necessary. Is the wiring intact? (If yes, proceed to step 2; if no, repair the wiring and retest.)
2. 22. Check the steering angle sensor's voltage output using a multimeter. Do you see a voltage between 0.5V and 4.5V? (If yes, proceed to step 3; if no, replace the steering angle sensor.)
3. 33. Verify the sensor calibration. Using a scan tool, ensure the sensor's angle is correctly calibrated. Is the calibration within specs? (If yes, further diagnosis needed; if no, recalibrate the sensor.)

• Faulty steering angle sensor
• Wiring issues or shorts in the sensor circuit
• Corroded connectors
• Calibration issues after front end work
