Hey Thanks! I ran the codes again, having just replaced the purge valve and vacuum detection pump at the evap canister, and there are no evap codes.... just P0420 "threshold bank 1" Could an O2 sensor cause the "GasCap" dash code? My other worry is that I did not use Mopar parts and it now can't see the new parts. I have a new Mopar gas cap...

You mentioned exhaust, how would that effect the "gascap" dash code?

Hey Jeep Guy!

Need some help. I have ordered a new catalytic converter and want to know how to order the "correct" 02 sensors? First, I know it takes two on the 3.5, one before and after the converter. However, my concern is I will order two online only to find out they are not considered OEM and thus not recognized by the Pacifica's PCM.

Is this even an issue as I have heard before? Or if it is, how can I be sure I have ordered 02 Sensors that will function properly and clear the P0420 code and then the "Check Engine" light on the dash?

Thanks, open to ALL SUGESTIONS!
