Inspect for a split purge valve vapor hose.

This bulletin applies to 2015 Jeep Grand Cherokee vehicles. P0455 (system large leak) or P0456 (system small leak) may be set in the PCM. The evaporative purge valve hose may be split that prevents the EVAP system from sealing. Specifically, this applies to vehicles built on or after November 16, 2014. 

If a split hose is found, replace the hose. For vehicles equipped with a 5.7L engine, use P/N 68189065AD. For a 3.5L engine, use P/N 68189075AE.
