How long does it take to clear all the OBD 2 monitors?
 

Need my 3.0 to pass emissions in GA and I get a random o2 sensor code that keeps it from passing. I reset the code and reset the (starts with the letter “a” can’t recall what it was. ) I’ve now driven 250+ miles, and at hiway speeds and the catalyst monitor hasn’t completed the cycle.

How much more time do I need to give it?

Well crap- I’m way past that. Hmm.

Doesn't matter how far you drive, if some of the conditions above aren't met. The readiness states requires a mix of driving modes in order to complete the checks.

Thanks, I’ve done all of the above multiple times. I’ll be getting it up to about 70mph today, maybe that’ll do it.

Drove another 100 miles today various speeds. Still missing one monitor. May swap 1 o2 tomorrow since Bank one pre-catalyst ocassionally throws a code.
