Driver Seat Position Sensor Fault

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

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 monitors how far the driver's seat is adjusted forward or backward. If it's faulty, the computer can't tell the seat's position, which can affect airbag deployment.

What the computer is actually seeing

The computer expects the driver's seat position to provide a voltage signal between 0.5V and 4.5V as it moves. If the signal is outside this range or missing, it triggers the fault code.

What a healthy reading looks like

0.5V to 4.5V based on seat position adjustment.

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 harness under the driver's seat for any visible damage, pinches, or wear. Repair as necessary. DECISION: No damage = go to step 2; Damage found = fix and retest.
  2. 22. Check the connector for the seat position sensor for corrosion or looseness. Clean and secure if needed. DECISION: No issues = go to step 3; Issues found = repair and retest.
  3. 33. Use a multimeter to measure the voltage at the seat position sensor while adjusting the seat. Check for 0.5V to 4.5V during movement. DECISION: Voltage within range = sensor good, look for software update; Out of range = replace sensor and retest.

Common causes

  • Faulty seat position sensor
  • Wiring issues in the seat position circuit
  • Connector corroded or loose
  • Software glitch in the body control module

Typical repair cost

Frequently asked questions

Is it safe to drive with this code?

Yes, but be cautious as seat positioning can affect airbag deployment.

Will this code reset itself?

It may clear if the issue is resolved, but a manual reset may be necessary after repairs.

How does this impact the vehicle?

If the seat position isn't accurately tracked, it can pose a risk for airbag deployment during a crash.
