Fuel Fill Door Open Request Sensor or Switch Stuck On
The open-request switch is stuck in the active state - the ECU continuously reads a request to open the fuel fill door. Either the switch is mechanically held closed or the line is shorted to its active level.
Affected components
- Fuel fill door request switch
Common causes
- High likelihood: Switch contact mechanically stuck closed
- Low likelihood: Carbon or debris buildup preventing free movement
- Low likelihood: Component wear with age - mechanical play
