P0442 small evap leak
P0442 small evap leak
The car failed the emissions test with 3 monitors incomplete and a P0442 evap small leak. The gas cap checked out ok. Not having access to a smoke machine here, has anyone noticed a common evap problem with these cars. Also the fault shows as permanate and will not clear.

Not sure about the 9C1, but that's a common code on '07-'14 Tahoes. The fix, if tightening/replacing the gas cap, is to replace the purge solenoid, harness & hoses.

Re: P0442 small evap leak
On another note. The car also has consumed 3/4 of a tank of fuel in 70 miles. I did jump on it a few times but mostly cruising. Its at the dealer now as I have limited diagnostic abilities here. Fingers crossed its a warranty issue.

Re: P0442 small evap leak
I had mine in for this exact problem 4x. First was the gas cap which didnt even make it home and the CEL came back, 2nd was the cannister being replaced and this last 3 days. 3rd trip was a purge valve which lasted about a month. Not sure what they did 4th time but they repaired a leak in a line and that has kept it off for a while now. EVAP LEAK=EVAP money from your wallet. Sad thing is mine was taken to the dealer to fix and still need 4x to fix!

Wow how many stories are you going to tell us about your "great" dealership working you over? Guess they make back that "Courtesy discount" on the parts with you on a regular basis...ejf2461 wrote:I had mine in for this exact problem 4x.
