  • Fuel level sensor harness is open or shorted
  • Fuel level sensor circuit poor electrical connection

How do I fix code P0462?

  Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

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 persists it may be necessary to replaced the fuel level sensor.

Cost of diagnosing the P0462 code

  The cost of diagnosing the P0462 code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.

When is the code detected

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

Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Incorrect fuel level reading

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.
