Steering Wheel Position Sensor Malfunction
The steering wheel position sensor is reporting an incorrect signal.
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 tells the car's computer where the steering wheel is at all times. If it's broken or sending wrong info, the car can have steering issues or even cause safety systems to malfunction.
What the computer is actually seeing
The computer expects a voltage signal that correlates with the steering wheel's angle. Normally, this should be a varying voltage of about 0.5V to 4.5V depending on the position, returning to around 2.5V when centered.
What a healthy reading looks like
Steering wheel angle should return a signal between 0.5V to 4.5V according to the angle; ideally, around 2.5V when straight.
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 wiring and connectors from the steering wheel position sensor to the ECU. Look for fraying or damage.
- 2Check the sensor's voltage output with a multimeter. It should vary between 0.5V and 4.5V based on steering angle.
- 3Perform a steering sensor calibration if you've just replaced any components related to the steering system.
- 4If the sensor output is incorrect, replace the steering wheel position sensor.
Common causes
- Faulty steering wheel position sensor
- Wiring issues from the sensor to the ECU
- Corrosion or dirt in the connector
- Calibration issues after repair or replacement

Frequently asked questions
Is it safe to drive with this code?
It's better to avoid driving until it's fixed, as steering assistance may be affected.
Will the code come back after clearing it?
If the issue isn't resolved (e.g., wiring/sensor), it will likely return.
Why does this code also show up with other codes?
Many steering-related issues can trigger multiple codes, indicating there's a problem with the steering system as a whole.
