Left Front Seat Position Sensor Circuit Failure
There’s a problem with the left front seat 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 seat position sensor checks how far the seat is pushed back or forward, and if it's broken, the computer doesn't know where the seat is.
What the computer is actually seeing
An electrical signal that should fluctuate between 0.5V to 4.5V based on seat position is stuck or shows an incorrect value (e.g., 0V or above 5V).
What a healthy reading looks like
The voltage from the sensor should be between 0.5V (fully back) and 4.5V (fully forward).
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. Check the wiring and connectors at the left front seat for damage or corrosion. Repair as necessary. Decision Point: Are the connectors and wires in good condition?
- 22. Using a multimeter, measure the voltage at the seat position sensor's connector. Expected voltage should be between 0.5V and 4.5V. Decision Point: Is the voltage within the expected range?
- 33. If not, replace the seat position sensor. Decision Point: Did replacing the sensor resolve the code?
- 44. If the voltage is correct, check for fault codes in the ECM/BCM that might indicate a communication issue. Decision Point: Are there other fault codes present?
Common causes
- Faulty seat position sensor
- Wiring issues or broken connectors
- Faulty ECM/BCM interference

Frequently asked questions
Is it safe to drive with this code?
Yes, the vehicle is drivable but the seat adjustment may not function properly.
Will the code come back after clearing it?
It may come back if the underlying issue isn't fixed.
Why does it pair with other codes?
Sensor circuits often share wiring and can have overlapping issues, especially if there's a wiring problem.
