Evap System Integrity Module Detector

The Mopar Evap Integrity Module is attached to your Jeep's vapor canister to regularly check the vapor canister and EGR system and make sure that it is functioning properly. If there is an issue at the module then you may get a "Check Engine" light on your dash pointing to your emissions system. If the module is bad, it is simple to snap a new one into the charcoal canister and plug in the factory connections. This is a genuine part from the factory so it is guaranteed to fit and perform like the original part.
