Jeep Wrangler PCM and module repair and replacement

Smog readiness test showing pass then incomplete

There was a servide bulletin out on o2 sensors. Find a smog shop that knows their stuff and you'll be fine.

Dang. California should really get Leno's law on the books. Theres no need for strict emission controls on a 25 plus year old car.

I agree! There are a lot of cars I would love to build that I could never get to pass smog. And my Jeep would probably pass the sniff test it's just the damn readiness checks.
 
So my O2 sensor heater and the O2 sensor itself have been showing good for a few days now. It has fooled me before so I am not super excited, but all i need right now is for the CAT to be ready and I will go directly to a smog shop. 🤞

Well crap... The O2 sensor readiness dropped out. The O2 heater is still completed though. This is seriously annoying. lol
Anyone know what its looking for to set the O2 ready?
