Front Passenger Seat Occupancy Sensor Circuit Fault
A fault in the front passenger seat occupancy sensor circuit has been detected.
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 has a sensor that tells if someone is sitting in the front passenger seat. If that sensor fails, the car might not know there's a passenger, which could affect airbags and seat belt warnings.
What the computer is actually seeing
The airbag control module sees an out-of-range or improper signal from the seat occupancy sensor, likely indicating it is not detecting a properly seated passenger when it should.
What a healthy reading looks like
Voltage should be between 0.5V (no weight) and 4.5V (weight detected).
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 passenger seat occupancy sensor connector for physical damage or corrosion.
- 22. Check the wiring for shorts, breaks, or frays.
- 33. Measure voltage at the sensor connector: should be 0.5V to 4.5V. If out of range, replace the sensor.
- 44. Verify the airbag control module is functioning—check for other codes.
- 55. If applicable, ensure the seat was recalibrated after any repairs.
- 66. Clear the code and see if it returns after driving the vehicle.
Common causes
- Faulty seat occupancy sensor
- Damaged wiring or connectors
- Failed airbag control module
- Moisture intrusion in connector
- Calibration issue after repairs

Will the code come back after clearing?
It may if the underlying issue isn't fixed.
Why might this pair with other codes?
Issues in the same circuit can trigger multiple fault codes.
