Catalyst monitoring and EGR will not test

nissannut · Dec 18th, 2003, 11:17 AM

I cleared my DTC codes after changing a bad o2 sensor. Now my EGR and Catalyst monitoring tests will not complete. I need these to complete for emissions testing to pass.

I have driven over 300 miles, 15 days.

Any ideas.. 96 Pathfinder 3.3.

it's not always how far you drive to readapt the car, but how you drive it. i can't remember the drive cycle off the top of my head, but i know that you have to go over 50mph for more than 1 minute with no load, and at operating temperatures. i'll read on and keep posting.

Thanks,

I just went back to the emissions place and with egr and catalyst still not ready it passed!!!!!!!! The big one is the O2sensor testing.

The guy said these 2 are not that important... At least I am legal again..
