Fuel level sensor short circuit to ground.
â–¶ How to fix
• Check wiring (to fuel level sensor) • Check connectors (to fuel level sensor) • Check fuel level sensor • Check the mechanical function of the fuel level sensor. • Measure the sensor voltage between signal and ground.
What you'll see
No driver-visible symptom recorded.
System reaction
Fuel level gauge shows empty fuel tank (as long as the fault is present).
Diagnostic depth
Detection
Impermissible signal from the main fuel level sensor (located close to the middle of the fuel tank). The sensor voltage level is too low. The fuel level sensor is short-circuited to ground.
Possible cause
• Defect wiring (short circuit to ground) • Defect connectors • Defect fuel level sensor
