Fuel Filler Cap: Description and Operation
Fuel Filler Cap
NOTE: If a fuel tank filler cap requires replacement, use only a fuel tank filler cap with the same features. Failure to use the correct fuel tank filler cap
can result in a serious malfunction of the fuel and EVAP system.
The fuel fill pipe has a tethered fuel filler cap.
A torque-limiting device prevents the cap from being over-tightened.
To install the cap, turn the cap clockwise until you hear audible clicks. This indicates that the cap is correctly torqued and fully seated.
A fuel filler cap that is not fully seated may cause a malfunction in the emission system.
