Seat Heater Sensor Circuit Short to Ground
There's a short in the seat heater sensor circuit.
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 computer is seeing less resistance in the seat heater circuit than it should due to a short, which can prevent the heater from working properly.
What the computer is actually seeing
The seat heater control module expects a resistance value of around 10-15 ohms from the sensor. If it sees 0 ohms, that's a direct short to ground.
What a healthy reading looks like
Expected resistance at the seat heater sensor should be 10-15 ohms.
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. Check the seat heater sensor connector for any signs of damage or corrosion. Repair as necessary.
- 22. Inspect the wiring between the connector and the seat heater element for fraying or breaks. Fix any issues found.
- 33. Measure the resistance of the seat heater element. It should be within 10-15 ohms. Replace if it's below 9 ohms or above 16 ohms.
- 44. If the wiring and element are good, check for shorts to ground by disconnecting the connector and measuring resistance from the pin to the ground. Any reading below 5 ohms indicates a short to ground elsewhere. Clear the code and retest.
Common causes
- Wiring damaged or frayed near the seat
- Faulty seat heater element
- Water or moisture intrusion causing a short
- Connector corrosion or loose connections

Will this code come back after clearing?
It can if the underlying issue isn't resolved, like a short or bad element.
Why does this code pair with other seat heater codes?
These codes often reflect similar issues in the seat heater circuit.
