Left Front Seat Position Sensor Circuit Range/Performance Problem
Issues detected with the left front seat position sensor data.
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 left front seat position sensor isn't giving the right info to the computer. It’s supposed to send values between 0-5 volts based on the seat's position, but it’s either out of range or not working at all.
What the computer is actually seeing
The computer expects the left front seat position sensor to report a voltage between 0.5V to 4.5V. If it reports below 0.5V or above 4.5V, or there's a total failure, the fault code triggers.
What a healthy reading looks like
Voltage from the left front seat position sensor should range between 0.5V and 4.5V based on the 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.
- 11. Inspect the wiring and connectors for damage or corrosion. Repair as needed. (Decision: if repair is made, clear codes and retest)
- 22. Check the seat position sensor reading with a multimeter while adjusting the seat. Expect voltage between 0.5V and 4.5V. (Decision: if out of range, replace the sensor)
- 33. If the sensor checks good, inspect the seat track movement for any physical obstruction that may affect sensor performance. (Decision: if obstruction found, clear it and retest for codes)
Common causes
- Faulty left front seat position sensor
- Wiring damage or open circuit
- Corroded connectors at the sensor
- Seat adjustment mechanism interference

Frequently asked questions
Is it safe to drive with this code?
Yes, but you may not have proper seat positioning adjustments, so fix it soon.
Will this code come back after clearing?
If the underlying issue isn't fixed, it will likely return.
Why does this code pair with other seat sensor codes?
The system monitors multiple sensors, so issues in one can trigger related codes.
