Driver Seat Position Sensor Circuit High Input
The driver seat position sensor is sending high voltage signals to the computer.
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 seat position sensor tracks how far the driver's seat is forward or backward and sends that information to the vehicle's computer. If it sends a voltage higher than 4.5 volts instead of the expected range, it triggers this code.
What the computer is actually seeing
The computer expects a voltage between 0.5 and 4.5 volts from the seat position sensor, but it sees a voltage above 4.5 volts.
What a healthy reading looks like
Expected voltage from seat position sensor: 0.5V to 4.5V; anything above indicates a fault.
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 wiring and connectors for damage or corrosion. Fix any visible issues - if wiring is intact, proceed to next step.
- 22. Measure the voltage at the seat position sensor connector with the ignition on. It should read between 0.5V to 4.5V. If it’s above 4.5V, replace the sensor.
- 33. If the voltage is within range, check for shorts in the harness leading to the seat position module. Test continuity and resistance. If okay, check the module itself.
- 44. If all wiring is good and the sensor is functioning, consider recalibrating or replacing the driver seat module.
Common causes
- Faulty seat position sensor
- Wiring issues or shorts in the harness
- Corroded connectors
- Faulty driver seat module (if equipped)
- Calibration issue or improper installation after repairs

Frequently asked questions
Is it safe to drive with this code?
Yes, it's drivable but may affect driver comfort and seat adjustment functions.
Will this code return after clearing?
It may return if the root cause isn't fixed, like a faulty sensor or wiring issue.
Why does this code pair with other seat-related codes?
Multiple codes may indicate shared wiring or common components failing together.
