Driver's Seat Position Sensor Circuit Malfunction
The seat position sensor is not providing a valid signal to the module.
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 driver's seat has a sensor that tells the computer where the seat is. If it stops working properly, the computer can't adjust the airbag deployment correctly.
What the computer is actually seeing
The seat position sensor data is out of range or missing. This usually happens if the voltage or resistance changes unexpectedly when the seat moves.
What a healthy reading looks like
Voltage from the seat position sensor should be between 0.5V to 4.5V depending on the 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 wiring and connectors related to the seat position sensor for damage or corrosion. If found, repair or replace as necessary. Decision: If wiring is fine, proceed to step 2. If damaged, fix it and recheck code.
- 22. Check the resistance and voltage of the seat position sensor with a multimeter. Ensure it reads within the expected values. Decision: If readings are correct, proceed to step 3. If incorrect, replace the sensor and recheck code.
- 33. Verify the functionality of the seat control module by checking for any stored DTCs and performing a self-test. Decision: If no other codes appear and the module functions properly, the fault may be environmental or intermittent. If other codes or failures occur, replace the seat control module.
Common causes
- Damaged or corroded wiring
- Faulty seat position sensor
- Loose connector at the sensor or module
- Faulty seat control module

Frequently asked questions
Is it safe to drive with this code active?
Yes, but be aware that the airbag deployment may not function correctly in an accident.
Will this code clear itself?
Not usually; you'll need to fix the underlying issue and clear the code manually.
Why does this issue sometimes accompany a B0062 or B0065?
Those codes relate to other seat position sensors; if there's a wiring issue, multiple sensors may report faults.
