Driver's Seat Position Sensor Circuit Malfunction

There's a problem with the driver's seat position sensor signaling the computer.

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 seat position sensor helps adjust your seat to the right position. If it's malfunctioning, the seat might not move as it should, or the system may not know where the seat is positioned, which affects safety features like airbags.

What the computer is actually seeing

The computer sees an unexpected voltage or resistance from the seat position sensor, which should typically send a consistent signal when adjusting.

What a healthy reading looks like

The seat position sensor should normally output between 0.5V to 4.5V as per its position; anything outside this range indicates a fault.

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. Visually inspect the wiring and connector at the driver's seat for damage or corrosion. If there is damage, repair or replace as necessary.
  2. 22. Check for any blown fuses related to the seat adjustment system. Replace if needed and retest.
  3. 33. Measure the voltage at the seat position sensor connector while adjusting the seat. Expect 0.5V to 4.5V. If values are outside this range, proceed to the next step.
  4. 44. If the voltage is correct, test the seat position sensor with a multimeter for resistance. Confirm it varies according to the seat position as specified by the manufacturer. If not, the sensor is likely faulty and should be replaced.
  5. 55. If the sensor is fine, check the body control module for faults. Ensure it's communicating correctly with the seat sensor.

Common causes

  • Damaged wiring or connector to the seat position sensor
  • Faulty seat position sensor
  • Corroded or dirty connections
  • Faulty body control module (BCM)
  • Software or calibration issue in the BCM

Frequently asked questions

Is it safe to drive with this code?

Yes, it's generally safe to drive, but some safety features may be affected, particularly if the seat position adjustment is linked to airbag settings.

Will this code come back after a reset?

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

Why does this code pair with other codes?

It's common for multiple codes to show up when there's a shared system, like the seat adjustment and airbag systems.
