Steering Wheel Position Sensor Voltage Supply
There's a problem with the voltage supply to the steering wheel position sensor.
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 car's computer isn't getting the right voltage from the steering wheel position sensor, which helps it understand how you're turning the wheel.
What the computer is actually seeing
The computer detects an abnormal voltage reading from the steering wheel position sensor, typically lower than the expected 5 volts.
What a healthy reading looks like
Expect a steady voltage between 4.5 to 5 volts at the sensor connector when the ignition is on.
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. Check the steering wheel position sensor connector for corrosion or loose pins. Repair as necessary and retest.
- 22. Measure the voltage at the sensor connector with the ignition on. It should read between 4.5 to 5 volts. If not, suspect wiring issues or ECU problems.
- 33. Inspect the wiring harness for damage along the path to the ECU. Look for frays, cuts, or shorts. Repair as needed and retest.
- 44. If wiring is good and voltage is still wrong, replace the steering wheel position sensor and retest.
Common causes
- Damaged wiring between the sensor and the ECU
- Faulty steering wheel position sensor
- Bad connection at the sensor or ECU connector

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity; you can drive but should fix it soon to ensure safe steering control.
Will the problem come back after clearing the code?
If the underlying issue isn't fixed, yes, the code will likely return.
Why does this code sometimes pair with C0726?
C0726 is also related to the steering position sensor but may indicate a different fault like incorrect position readings.
