Default Emissions test... P0442 p0445

READ ALL TO UNDERSTAND

So this post is a FYI for smog/emission purposes...hope it helps someone.

Over the past year I have gotten the annoying "fuel filler cap-open loose" and dtc P0445(large Evap Leak) code. Smog time came so I changed fuel cap because thats what I thought it was....CEL still came on.....after reading about the code I checked the purge valve on the radiator(It didn't click when power was applied)replaced it, cleared code and drove awhile....CEL came back on after a day or so..new code was P0442(Small evap leak).........looked for cracked lines and found nothing.

I was so worried it wouldn't pass the emissions test....I read and read online..For those of you that have code readers, check out your reader.......if it has the function that tells you about the "System monitors" check those out.......here comes the good part.....here in California(Strict emissions)your vehicle only has to have 5 of these monitors as ready....what does that mean? Well, it means that you can clear your P0442 code and still pass the test........I cleared my code, drove until I had 5 of the monitors ready, then went and got my smog test......PASSED WITH FLYING COLORS.

Bad part is I still have to figure out why its coming on, but hey, at least i have my sticker to drive still. My suggestion for anyone is to call a Local smog station and ask how many monitors have to be ready...thats what I did.
