General Information

General Description

The Fuel Level Sensor (FLS) measures the fuel level in fuel tank and its information is used to supply the ECM with information regarding the monitoring condition of the EVAP canister purge system for leak detection. If the fuel level sensor is monitored for high or low stuck or difference between voltage of fuel level sensor and voltage deviation of fuel level sensor is exceeds limited value while driving, this is interpreted by the ECM as a fault

DTC Description

Checking output signals of fuel level sender under detecting condition, if the fuel level sender's signal is low than 3%, PCM sets P0462. MIL (Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
