I cannot get my xj to pass smog. can anyone tell me which are the primary catalytic converter & the secondary catalytic converter on a 2001 jeep xj? I know there are 2 catalytic converters under the hood in the engine compartment. 1 converter for 3 cylinders hence the 2 under the hood 1 converter for 3 cylinders. but is the secondary converter the one right before the muffler? I thought that was a resonator?? Any help is appreciated.

Primaries under the hood, secondary in front of the muffler. there should be an O2 sensor right after the cats. So you will have 3 O2 sensors. If you have a resonator it would look like a small Muffler, and be placed between the Cat and muffler or after the muffler.
