I had the battery out for a couple days while repainting the battery tray. That will set all my emissions monitors to "not ready" won't it?
I have searched and found the drive cycle info, but also found that it can take up to 500 miles for the cat test to set ready.
Illinois allows up to 2 monitors to show not ready and still pass. Does anyone know what two monitors take the longest to set ready, and how much driving I need to do to set all but two to ready? I don't want to drive around with expired tags for any longer than I have to.
Yes, I should have got it tested before the tags expired, but I was planning on selling it to someone in Indiana which doesn't require testing. Now that I'll be keeping the car, I am stuck with expired plates.
Yeah, you are going to have to get the monitors to set to ready. I had a similar problem and it I had my EGR and EVAP systems set to NOT READY for the longest. The cat and other systems set within the first 20 miles of driving. You might have better luck though (especially since you can pass with 2 systems not ready).
Protip: If you don't know what you're doing, don't do it.
