Definition
Evaporative Emission System Leak Detected Fuel Cap Loose or Off
Description
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  This DTC sets if the evaporative emission EVAP monitor detects a gross leak while the refueling flag is set and a loose fuel filler cap or an incorrectly sealed fuel tank filler pipe if equipped is suspected  On most vehicles when the DTC sets,  either the check fuel cap indicator illuminates or a message on the instrument panel cluster IPC displays to instruct the driver to check the fuel cap or capless fuel tank filler pipe if equipped
Cause
Damaged,  missing,  or loosely installed fuel filler capCapless fuel tank filler pipe damaged or not sealed correctly if equipped
Diagnosis
Check for a missing fuel filler cap or the integrity of the cap Verify the capless fuel tank filler pipe is sealed correctly if equipped Install and remove the supplemental fueling adapter five times in the capless fuel tank filler pipe to clear debris on the seal If OK, clear the continuous memory DTCs and test the system for correct operation
Failure Type
Circuit Open
This sub type is used for failures, where the control module determines an open circuit via lack of bias voltage, low current flow, no change in the state of an input in response to an output, etc
