About this part

This replacement gas cap seals the fuel filler neck and keeps fuel vapor inside the evaporative system. A cracked seal or a lost cap often sets an EVAP code and turns on the check engine light. The cap is non-locking and has a tether, which keeps it attached to the vehicle so it does not get left on a pump. It is a simple replacement for a worn or missing cap.

Installation notes

Check the filler neck for damage or rust before fitting the cap. Attach the tether as the old one was attached. Tighten the cap until it clicks, and allow some drive cycles for a stored EVAP code to clear.
