[QUOTE="appst8design, post: 462638, member: 23545"] 2015 JK Wrangler 3.6L with P0456 small EVAP leak. Started out with just the P0456 code but now has gas cap warning as well. -Tried erasing code with OBD scanner (CEL came back on) -Replaced gas cap, cleared CEL, CEL came back on. -Replaced Vapor Purge Valve, cleared CEL, CEL came back on. -Took to mechanic to have EVAP system smoked (didn't have any leaks) and replaced Evaporator System Integrity Module Detector, cleared CEL, CEL came back on. -Mechanic suggested there was a TSB for this exact problem (I can't find it) but it required reflashing PCM by dealership. Dealership says they don't reflash used PCM's. Would just resetting the PCM clear the permanent gas cap and CEL code that I just can't seem to get rid of? Any other suggestions on how to fix? Appreciate any help on this issue. [/QUOTE]
