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 fuel level change under detecting condition, if the fuel level difference between current and previous is lower than 3.5% while odometer difference between present and previous is higher than 125km, ECM sets P0461. MIL (Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
