Of course, it's inspection time & an error code pops up.Sure, why not now, the month I have to go to inspection.
It's a p0440, but we all know how to fix that one.
But the question is: After I use my scanner to clear the code; "How long do i have to wait before the system is "happy"? I can't clear the codes and go to inspection the next day, as they will fail me for clearing the computer. So what is the "age" time? 50 starts, 5 driving cycles, 30 days?
It's impossible to give you a concrete answer. You are supposed to be able to get it to reset by doing the OBDII drive cycle for GM (easily found online), but I've had a hell of a time getting the EGR and EVAP systems to set to ready in the past. On on occasion it took me more than 500 miles of driving to get it to set... it sucked.
Protip: If you don't know what you're doing, don't do it.
I'm going to wait about 3 weeks before I go. If they fail me, I can get an "ERF", Emission Repair Form. You take it & the car to an approved facility and they do the repairs "or you can do it yourself". If you do it yourself, all you have to do is show them the bills for the materials used in the repair. So I'll go buy a purge solenoid and do the repair, clear the code and show them the receipts. That would get me out of the "you cleared the codes" issue.
The code only sets about once a year, so I'm not even sure it's the solenoid, but it's a cheap enough repair. The problem is it chose to set itself this month.
