On my 97 Pathfinder the catalyst monitor hasn't gone ready for a while. Maybe over a year and I haven't paid attention to it before that to really know for sure how long its been like that.
But in my state, NY, you can pass emissions with a monitor not ready so ive never bothered with that.
Ive also tried all driving parameters to see if I can get it ready but no luck. Ive decided to ask a nissan tech a while ago and he said the vehicle has to drive long enough to heat up. Didnt believe that explanation too much but decided to try it and drove about 150 miles nonstop highway, even at high speeds and no luck at all with that.
However, now that ive seen others with the issue im curious as to why this monitor doesn't go in ready state.
And while were speaking of emissions, and I dont mean to digress from the issue at hand, but I do have a pesky p1441 code that appears every so often. Changed charcoal canister, vent valve, vacuum cut valve solenoid, bypass valve, smoke tested, new gas cap, and purge solenoid under hood. No luck, comes back every so often.
