The powertrain control module (PCM) continuously monitors the fuel level and retains the last updated value prior to the ignition switch being placed in the OFF position. After the ignition switch is placed in the ON position a new fuel level is taken and compared to the level recorded at ignition off. If the fuel level has increased, a flag is set in the PCM indicating the vehicle was refueled. If the evaporative emission (EVAP) monitor detects a gross leak while the refueling flag is set, a loose fuel filler cap or an incorrectly sealed fuel tank filler pipe (if equipped) is suspected and the DTC is set. On most vehicles when the DTC sets, either the check fuel cap indicator illuminates or a message on the instrument cluster displays to instruct the driver to check the fuel cap or capless fuel tank filler pipe (if equipped).
