P0464 Fuel Level Sensor - General Information

Component Location





General Description

PCM monitors the voltage output signals of the Fuel Level Sensor (FLS) (#1) and the Fuel Sub Sender (#2). The combined resistance of the two sensors in series enables the fuel gage to determine fuel tank level. PCM also uses values from both sensors to determine condition of the EVAP system for leak detection. PCM monitors both fuel level sensors for the conditions of being stuck high or low, and differences between voltages of fuel level sensors. PCM will calculate if voltage deviation of fuel level sensors has exceeded a limit value while driving. This would be interpreted by the PCM as a fault.

DTC Description

PCM monitors output signals from the FLS's, if difference between previous and current Fuel Level Signal is higher than 10%, the PCM sets a P0464 DTC. The Malfunction Indicator Lamp (MIL) turns on when the malfunction lasts consecutive 2 driving cycles.
