TITLE:
Loose Gas Caps and Check Engine Light

APPLIES TO:
All Models

SERVICE TIP:
A gas cap which is not properly tightened after refueling can cause EVAP DTC's and check engine light illumination. If you encounter related EVAP DTC's, check the fuel cap first. Also, very little effort is required on later model vehicles to properly secure the gas cap.
