Driver's Seat Position Sensor Circuit Range/Performance Problem

Issue with the driver's seat position sensor not operating properly.

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 position sensor tells the computer how far the seat is from a base position, and if it's out of range, it can't adjust the seat correctly.

What the computer is actually seeing

The seat position sensor is supposed to send a voltage signal between 0.5V to 4.5V depending on the seat position. If the voltage is outside this range or inconsistent, the code triggers.

What a healthy reading looks like

Voltage 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.

  1. 11. Inspect the wiring and connectors for the seat position sensor; look for any damaged wires or poor connections. If found, repair or replace as needed.
  2. 22. Measure the voltage at the seat position sensor connector with the seat in various positions. The voltage should change smoothly between 0.5V and 4.5V. If not, replace the sensor.
  3. 33. Check for proper ground at the seat position sensor; if you have a ground issue, repair as needed.
  4. 44. Clear the code and road test the vehicle. If the code returns, consider programming issues or a faulty body control module.

Common causes

Frequently asked questions

Is it safe to drive with this code active?

It's moderate severity; the vehicle is drivable but fix it soon to avoid comfort and safety issues.

Will this problem come back if I clear the code?

If the underlying issue isn't fixed, yes, it will likely return.

Why does this code pair with B2208?

B2208 also relates to seat position; they often trigger together if there’s a common fault.
