Fuel Level Sensor

Fuel level sensor is located in fuel tank. Sensor sends a signal to PCM and fuel gauge in instrument cluster. PCM uses fuel level sensor signal as one of the monitoring conditions for detecting EVAP control system DTCs. PCM also uses fuel level sensor input to control EVAP tank pressure control solenoid vacuum valve. If fuel level is greater than specified, PCM will operate EVAP tank pressure control solenoid vacuum valve to prevent fuel from flowing into EVAP charcoal canister from fuel tank.
