Typical repair cost: $100 – $800
Severity Level 1 — Low
This code indicates a minor issue that is unlikely to cause immediate driveability problems. You can typically continue driving but should have the vehicle inspected at your earliest convenience.
Common Symptoms
- Power seats working sometimes, failing other times
- Seat memory settings not saving or recalling correctly
- Power seat won't move in one or more directions
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Seat motor/module failing — output signal drifts outside expected range, common with age (80k-120k miles)
- Wiring or connector with intermittent high resistance — causes signal to fluctuate, especially with temperature or vibration
- Mechanical issue with the power seat system causing the sensor/actuator to operate outside its designed range
- Contamination or debris affecting seat motor/module operation — dirt, oil, or moisture interfering with readings
- Software/calibration issue in the control module — may need reprogramming rather than parts replacement
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($44-90 at shop, free at auto parts store for basic scan)
- Visually inspect the power seat system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $138 diagnostic fee at shop)
- Replace seat motor/module — slow degradation over time is the most common cause of range/performance codes, especially on vehicles with 100k+ miles ($100-800)
- Check for vacuum leaks, exhaust leaks, or mechanical issues that could be causing the power seat system to see out-of-range conditions ($81 diagnostic smoke test + repair)
- Update control module software/firmware — some range/performance codes are fixed by a PCM reflash from the dealer ($168 at dealer)
