Steering Position Sensor Circuit Failure
There’s a problem with the steering position sensor or its circuit.
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 position sensor tells the computer where the steering wheel is. If it’s not working right, the computer can’t adjust systems that help steer the vehicle, which can lead to handling issues.
What the computer is actually seeing
The computer checks for a valid voltage signal from the steering position sensor, usually between 0.5V to 4.5V depending on the steering angle. If it sees no signal or a fixed voltage that doesn’t change with steering angle, it sets this code.
What a healthy reading looks like
Expected voltage in the steering position sensor should range from 0.5V (full left) to 4.5V (full right) during operation, with a smooth transition in between as you turn the wheel.
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 damage or corrosion. Repair as needed. Check for proper ground connection at the sensor.
- 22. With the ignition on, measure the voltage at the steering position sensor connector while turning the wheel. Voltage should range from 0.5V to 4.5V. If fixed or outside this range, continue.
- 33. If the voltage is erratic or not within range, replace the steering position sensor. If the sensor is fine, check for wiring issues between the sensor and the computer.
- 44. Clear the code and test drive the vehicle to see if the code returns. If it comes back, further diagnose the ECM and wiring integrity.
Common causes
- Faulty steering position sensor
- Damaged wiring or connectors
- Poor ground connection
- Corrosion in the connector

Frequently asked questions
Is it safe to drive with this code?
It’s manageable for a short distance, but handling may be affected, especially in sharp turns or at high speeds.
Will this code come back after clearing it?
It might, especially if there’s an underlying issue that hasn’t been fixed.
Why do other codes appear with C0807?
They often relate to other components that rely on the steering sensor, which may show failure when the sensor itself isn’t functioning.
