Steering Position Sensor Circuit High Voltage
The steering position sensor circuit is sending a high voltage 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 position sensor is designed to detect the position of the steering wheel and sends this information to the computer. If the sensor's voltage reading is above the expected range, it throws this code.
What the computer is actually seeing
The vehicle's control unit sees a voltage from the steering position sensor that's higher than 5 volts, which is outside normal operation.
What a healthy reading looks like
Steering position sensor output should typically be between 0.5 to 4.5 volts when 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.
- 1Inspect the wiring and connectors for damage, corrosion, or shorts. - Decision Point: Are the connectors and wires in good shape? If yes, proceed to step 2.
- 2Check the voltage at the steering position sensor connector. It should be between 0.5 to 4.5 volts. - Decision Point: Is the voltage in range? If no, the sensor is likely faulty; if yes, proceed to step 3.
- 3Test the steering position sensor by wiggling the connector and observing the voltage output. - Decision Point: Do voltage changes occur with movement? If yes, replace the sensor; if no, check the vehicle control module.
Common causes
- Faulty steering position sensor
- Wiring issues (short circuit)
- Connector damage or corrosion
- Faulty vehicle control module (VCM)
