Possible causes

– Faulty fuel level sensor
– Fuel level sensor harness is open or shorted
– Fuel level sensor circuit poor electrical connection

Tech notes

Low fuel level can trigger this code. Before replacing any parts try filling up the fuel tank and erasing the engine code. If the problem persist it may be necessary to replaced the fuel level sensor.

When is the code detected?

An excessively low voltage is sent from the sensor is sent to Engine Control Module (ECM).

Symptoms

P0462 Description

The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the Engine Control Module (ECM). The fuel level sensor consists of two parts, one is mechanical float and the other side is variable resistor. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.
