When a vehicle’s PCM (Powertrain Control Module) logs a P0462 trouble code, it’s because its fuel level sensor is no longer taking correct readings.
What does P0462 mean?
OBD-II Code P0462 is defined as a Fuel Level Sensor “A” Circuit Low. The Fuel Level Sensor tells the engine control module (PCM) how much fuel is in the fuel tank. When the PCM detects an irrational signal from the fuel level sensor, it will set code P0462. The Fuel Level Sensor may be part of the fuel pump.
