Steering Wheel Position Circuit Range/Performance Problem
The steering wheel position sensor is reporting a problem with its range or performance.
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 wheel position sensor monitors the angle and position of the steering wheel. If it detects that the angle is outside its normal range or it's not functioning properly, it throws this code.
What the computer is actually seeing
The computer expects the steering wheel position voltage to vary between 0.5V (full left) to 4.5V (full right) based on the position of the steering wheel.
What a healthy reading looks like
Steering wheel position voltage should range from 0.5V to 4.5V under normal conditions; check for smooth transitions between these values as the 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.
- 11. Inspect the wiring and connector for the steering wheel position sensor. Look for signs of damage, corrosion, or loose connections. Fix any issues found. Decision: If no issues found, proceed to step 2.
- 22. Use a multimeter to check the voltage at the steering wheel position sensor. With the ignition on, the voltage should range between 0.5V and 4.5V while turning the steering wheel. Decision: If voltage is out of range, replace the sensor. If within range, proceed to step 3.
- 33. Check for any software updates or reprogramming needs in the vehicle's control module. If an update is available, apply it. Decision: If the issue persists after the update, consider replacing the sensor.
Common causes
- Faulty steering wheel position sensor
- Wiring issues in the sensor circuit
- Faulty steering column connectors
- Software issues in the vehicle's control module

Frequently asked questions
Is it safe to drive with this code?
It's safe to drive, but it may affect steering response and assist features, so plan to fix it soon.
Will the code come back after clearing it?
If the underlying issue isn't fixed, yes, it will likely return.
Why does this code pair with C1189?
C1189 is often related as a secondary error code indicating another issue with the steering position system.
