Code P0462 1999 Ford F150 Description

The P0462 diagnostic trouble code for a 1999 Ford F150 refers to the Fuel Level Sensor Circuit Low Input. This code indicates that the fuel level sensor is reporting a lower than expected voltage signal to the vehicle's engine control module (ECM) or powertrain control module (PCM). The fuel level sensor is responsible for sending information about the amount of fuel in the tank to the ECM, which then uses this data to calculate fuel consumption, adjust air-fuel ratios, and activate warning lights on the dashboard.

Tech Notes for P0462 1999 Ford F150

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.



The PCM monitors the fuel level input (FLI) circuit for electrical failure. The test fails when the signal moves below the minimum allowable calibrated parameter for a specified fuel fill percentage in the fuel tank

When is the Code Detected?

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