Emissions are really pissing me off....

So the check engine light was on in my step daughters car. The body is junk but it runs like a top (teal 96 Intrepid), has about 180K on it.

I had the car for a week, replaced cradle bushings, LCA and strut bushings, bought new tires and had it aligned. While I was at it I replaced the B1P2 O2 sensor and cleared the codes. Fast forward about 1500 miles and 3 weeks, the car has now been to emissions 3 times and won't pass because it says ODB NOt Ready, I have no clue what to do next.

Anyone have this trouble? Ideas are welcome

She will keep driving it but it is dangerous because the plates are expired, its a catch 22. How can I tell when its ready so we don't take it back and fail?

If memory serves, thee was a flash update for the engine controller, (PCM) to fix this issue. If you have the controller number I can check this for you. Seems the OBDII counter was forgetting to log ignition counts so, even if you did manage to get all the monitors to run, you would lose them at the next key cycle. Basically starting over at every key cycle.

What's the controller number? Is this on the ECM?

The TSB I looked up was 18-005-01. for the 1996 LH Intrepid 3.5L

There are four controller numbers that all the others superceed to, and there are quite a number of them. All I can do at this point is give you info as you will need to have this PCM programmed to fix this issue.

The four updated numbers are:

4606453
4606355
5012676
5012677

In most cases I've seen, it is best to have the controller number read by a scan tool as the label on the outside is just the original number. If at any time the controller was updated there was a label that was supposed to be attached to the PCM and the body underhood. Many times the label for the PCM was neglected.
