I keep getting the check engine light with a code o P0442, I have changed gas cap along with the purge valve under the hood, and still keeps throwing the code. I went and had the local dealer do the smoke test and they informed me there was a leak in tank just above the filler hose, I dropped the tank again and pressure tested the tank with air and used soapy water and couldn't find any leaks or small holes, inspected all lines and couldn't find any visible leaks or holes any ideas on what else I could check or what the problem might be? The dealer told me I need to replace the filler pipe and tank at a cost of 1600-2000 dollars. Really appreciate any help.
have the same problem?
