Help with OBD2 testing and getting "ready"... Sign In

I own a 2001 Accord EX in California and I am having problems with something that causes the TCS light and the CEL light to come on. This problem happens at 55ish+ MPH which leads me to believe it has something to do with the EGR "ready" test since it seems to be the only one based on higher speeds.

There are more obvious problems such as a Transmission that is starting to go bad. At higher speeds the car starts to shake slightly which I assume is related to the TCS light. I need to wait till taxes to get the Trany fixed but my smog is due soon.

My first attempt made in ignorance was to disconnect the battery to reset the light and then take it to the smog shop (duh). I have now found the info on how to set all 5 tests to "ready" thanks to this great forum of helpful people (cheers!!).

My question is... If I manage to "ready" the other 4 checks and the EGR shows "not ready" will the car pass if everything else checks out? I read both that all checks should be "ready" and I also read that 4 of 5 should be "ready" on a 2001 car?

Thanks for your time!!

That is determined by your state. I don't know what CA rules are. It doesn't sound like you have found or repaired the original problem anyway. Clearing the codes doesn't fix anything.
