My darling 2004 LE has begun throwing code 0442 every day now for the past couple weeks and lites the mil lite aka check engine lite. It was going to the dealer for a freebie air bag ECU recall so I figured I would have them take a look see. Mileage = 145k.
They didn't find anything obvious but said they could smoke test the gas tank and fart around with it until they secured a costly repair bill. I nixed the smoke test and asked what is the most likely culprit since there is clearly a problem. They suggested a new gas cap which they installed. 12 miles later and we are back to code 0442 evap emission small leak. Has anybody been successful finding a root cause and long term solution for this little nuisance?
