DTC P0463: Fuel Level Sensor (Gauge) Circuit High Input: Condition

DTC is set when Powertrain Control Module (PCM) detects high input voltage from fuel level sensor. This is a continuous monitor. MIL is illuminated when PCM detects malfunction during 2 consecutive drive cycles. Possible causes are:

• Short or open circuit between fuel level sensor, fuel level gauge and PCM.
• Fuel level sensor malfunction.
• PCM malfunction.
