Fuel System - EVAP DTC's & Check Engine Light

SOURCE: Mitsubishi Tech Talk Article November 2004

TITLE: Loose Gas Caps & Check Engine Light

APPLIES TO: All models

SERVICE TIP:

A gas cap which is not properly tightened after refueling can cause EVAP DTCs and check engine light illumination. If you encounter related EVAP DTCs, check the cap first. Remember, a loose gas cap is not a warranty repair. Also, very little effort is required on later model vehicles to properly secure the gas cap.
