Driver Seat Position Sensor Circuit Malfunction
The system detects a malfunction in the driver seat position sensor circuit.
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 tells the computer where the driver's seat is located. If this sensor isn't working right, it can't tell if the seat is in the right position, which can impact airbag deployment.
What the computer is actually seeing
The computer is looking for a voltage signal typically between 0.5V (full rear) to 4.5V (full forward) from the seat position sensor. If it gets a signal below 0.1V or above 4.9V or if it doesn’t get any signal at all, it throws this code.
What a healthy reading looks like
Voltage should range from 0.5V to 4.5V depending on seat 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.
- 1Check for any visible damage or corrosion on the seat position sensor connector and wiring. Repair if necessary.
- 2Using a multimeter, measure the voltage at the seat position sensor connector.
- 3- If voltage is within 0.5V to 4.5V, proceed to test the sensor itself for functionality. - If voltage is not within specs, check wiring continuity to the PCM (Powertrain Control Module).
- 4Test the seat position sensor by removing it and checking its resistance and operation according to the manufacturer's specifications. - If the sensor fails, replace it. - If the sensor is good, investigate further into the PCM or wiring issues.
Common causes
- Faulty driver seat position sensor
- Damaged wiring or connectors
- Corroded connections
- Faulty occupant classification system

Frequently asked questions
Is it safe to drive with this code?
Yes, it is drivable but fix it soon. It affects airbag deployment.
Will this code come back after I've cleared it?
If the root issue isn't fixed, the code will likely return.
Why am I seeing this code along with other airbag codes?
Malfunctions in the seat position sensor can affect airbag function, triggering multiple related codes.
