Front Left Seat Position Sensor Circuit Failure
The seat position sensor is sending incorrect signals.
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 seat is moved forward or back. If it's faulty or has a bad connection, it won't tell the computer where the seat is, which can affect safety features like airbags.
What the computer is actually seeing
The vehicle's body control module sees an unexpected voltage level or a complete lack of signal from the seat position sensor, which should normally send a range from 0.5V (fully back) to 4.5V (fully forward).
What a healthy reading looks like
Expected voltage from seat position sensor should range between 0.5V and 4.5V depending on the seat's position. Any signal outside this range or a consistent 0V 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 the seat position sensor wiring for damage or wear. Look for frayed wires or corrosion on connectors.
- 22. Check the seat position sensor connector to ensure it is seated properly and clean. Reconnect if necessary.
- 33. Using a multimeter, measure the voltage at the seat position sensor while moving the seat through its range. Verify it fluctuates between 0.5V and 4.5V.
- 44. If the voltage is not within the expected range, replace the seat position sensor. If the voltage is correct, check the body control module for error codes.
Common causes
- Broken or damaged wiring to the seat position sensor
- Corroded or loose connector at the sensor
- Faulty seat position sensor
- Issues with the body control module

Will this code come back after I clear it?
If the underlying issue isn't fixed, the code is likely to return after some use.
Why does this code pair with other codes?
Other seat-related codes often indicate a problem in the same circuit or system affecting multiple sensors.
