Steering Wheel Position Sensor Circuit Malfunction

There's a problem with 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 steering wheel position sensor tells the computer how much you're turning the wheel. If it doesn't work, the computer can't adjust things like power steering properly.

What the computer is actually seeing

The computer expects a variable voltage signal between 0.5V and 4.5V, representing the steering angle. If the signal is outside this range or constant, the code is triggered.

What a healthy reading looks like

Normal steering wheel angle voltage should fluctuate between 0.5V (full left) and 4.5V (full right) depending on the steering wheel position.

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.

  1. 1Step 1: Inspect the wiring and connectors for the steering wheel position sensor. Check for damage or corrosion.
  2. 2Step 2: With the ignition on, use a multimeter to measure the voltage on the sensor connector. It should fluctuate between 0.5V and 4.5V when the wheel is turned.
  3. 3Step 3: If the voltage is static or outside specified range, replace the steering wheel position sensor. If it's within the range, proceed to the next step.
  4. 4Step 4: Check for any mechanical binding in the steering column that may affect the sensor's readings. Ensure the sensor is aligned properly.
  5. 5Step 5: Clear the code and test drive the vehicle. If the code returns, consider checking the vehicle's ECU for faults.

Common causes

  • Faulty steering wheel position sensor
  • Wiring issues or damaged connectors
  • Steering column misalignment or obstruction
  • Faulty ECU (less common)
