Passenger Seat Position Sensor Circuit Range/Performance Problem
There’s an issue with the passenger seat position sensor not reading correctly.
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 computer can't tell how far the passenger seat is moved forward or back, usually due to a bad sensor or wiring. It expects readings like 0 volts (fully back) to 5 volts (fully forward).
What the computer is actually seeing
The passenger seat position sensor should signal a specific range of voltages corresponding to its position. If it sees values outside of that (like a short circuit or an open circuit), it triggers this code.
What a healthy reading looks like
Expected voltage range is 0 to 5 volts. Voltage should change smoothly as the seat moves.
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 harness to the passenger seat position sensor for damage, frays, or corrosion. Fix any issues found.
- 22. Inspect the connector for the seat position sensor. Ensure it’s fully seated and free of corrosion.
- 33. Measure the voltage at the sensor connector while moving the seat. Look for a smooth voltage change between 0 to 5 volts as the seat moves. If voltage isn’t changing, the sensor might be bad.
- 44. If the sensor shows the correct voltage, check the seat position sensor's ground connection; it must be stable and less than 0.1 ohms to ground. If it fails, repair the ground.
- 55. If all above tests are good, replace the passenger seat position sensor.
Common causes
- Faulty passenger seat position sensor
- Wiring issues such as breaks or shorts in the circuit
- Poor connector contact at the sensor or the module
- Calibration issue after part replacement

Frequently asked questions
Is it safe to drive with this code?
Yes, but without a functioning seat sensor, the airbags may not deploy properly in a crash.
Will this code come back after clearing it?
If the issue isn’t resolved, this code will return.
Why does this code sometimes pair with B0034?
Both codes relate to seat position circuits, indicating similar issues but possibly in different circuits.
