Power Seat Position Sensor Circuit Range/Performance Problem
The power seat position sensor is reporting a range or performance issue.
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 power seat isn't moving correctly or reporting its position properly, which can lead to it not working or being stuck in one place.
What the computer is actually seeing
The power seat control module expects to see a position signal that varies as the seat moves. If it receives signals outside of normal operation (like stuck readings or impossible ranges), it sets this code.
What a healthy reading looks like
The seat position signal should vary between 0.5V (full rear) to 4.5V (full front) as the seat adjusts. If the voltage stays constant or is out of this range, there's an issue.
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 power seat wiring harness for cuts, shorts, or corrosion. Repair if necessary. Decision: Is wiring intact? Yes -> Go to step 2; No -> Repair wiring and retest.
- 22. Check the power seat position sensor connector for proper engagement and pin damage. Decision: Is connector good? Yes -> Go to step 3; No -> Repair or replace the connector and retest.
- 33. Measure the voltage at the power seat position sensor while moving the seat through its entire range. Decision: Do voltages vary between 0.5V to 4.5V? Yes -> Replace power seat position sensor; No -> Go to step 4.
- 44. Check for mechanical binding in the power seat assembly. Ensure there are no obstructions. Decision: Is the mechanism free? Yes -> Replace power seat module; No -> Free the binding and retest.
Common causes
- Faulty power seat position sensor
- Wiring issues (broken, shorted, or corroded wires)
- Faulty power seat module
- Mechanical binding in the seat mechanism
Typical repair cost
$$ - $$$

Frequently asked questions
Is it safe to drive with this code?
Yes, but the power seat won't adjust properly, which can affect comfort and driving position.
Will this code come back after repairs?
If all issues are addressed properly, the code shouldn't return.
Why do I see this code with B1433?
These codes often appear together since they both relate to the power seat position sensor and can point to similar faults.
