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 from FLS under detecting condition, if Difference between previous and current Fuel Level Signal is high than 10%, ECM sets P0464. MIL (Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
