Question about 1999 Nissan Altima
I have a 99 altima and it had several codes, after I had 3 different mechanics look at it we decided to replace the intake manifold gasket. That fo=ixed everything except the knock sensor code. I was told by the emissions office it would not fail for just that code, however after 100 miles of driving over 5 days of city and highway the egr monitor has not reset. Until it will pass a monitor ready test I can't get a waiver if there are any more problems. Is there a specific drive sequence needed for this and if so where can I find it?
Hi Sandy, I'm glad to help!
Sandy just a week ago I fixed a Mitsubishi with the same problem. The EGR Monitor would not set, it turns out the vacuum solenoid that goes to the EGR Valve was bad. I replaced for the lady and it fixed the problem. NOTE: I can't say that is what's keeping your monitor from running. BUT, its a real cheap fix and worth a try, don't you think. Hope this helps and have an awesome day Sandy!

Putting miles on them wont reset the computer. It is how many times you cycle the key on and off. And they will only reset if the problem was fixed. I don't know how many times yours has to be cycled, but some vehicles are up to 100 times. Hope this helps.
