CEL P0430 fix that worked for me
 
Over the course of about 4 or 5 months, I kept tripping a CEL P0430 about every 3 or 4 weeks, especially after taking it on a longer trip (over 100 miles). I'd clear the code and sure enough it would come back.

After looking at nearly every post about this code, I found one that suggested that you check the gas cap and check for cracks in the rubber O-ring. Yep, mine had about 10 - 12 cracks in it

I got a new one from Pelican Parts for $15.50 including the pop rivet. (There are threads about how to remove the old pop rivet and for installing the new one.)

1000+ miles later and I haven't tripped the P0430 code once. Sometimes the problem isn't a big one or an expensive one. If I trip this code again soon, I'll be looking to replace some O2 sensors. Until then...

:cheers:

Good call! A fresh gas cap is the #1 cure for P0430. If you get the code again, look to gas tank venting and evap system. It will never be tripped by faulty O2 sensors.

Thanks for the info! I thought I read somewhere about the O2 sensors being an issue but I guess I was wrong.

Digging up this old thread doing a search. My 02 keeps tripping the 0430 code as well. And I am having problems with fueling my car, the pump clicks off and I have to reseat the nozzle a lot to reseat it. Can the vent system now be faulty giving me the code?

There is a post somewhere discussing the tank vent system creating problems with fueling and hot starts. I do not recall if it mentioned a CEL. A search for hot start issues might turn up the posts.

Don't know about the error code, but some CA gas pumps would click off instantly when I filled up because of their fume recovery sealing fill nozzles and the short fill tube and tight bends in the cars fill line. Took forever to get 1/2 tank even. Never happened since I drove it to UT.
