This is a Chrysler Town and Country 2008, 3.8L, 103 thousand miles. I just replace the engine 5 months ago.
I am able to use an ODB scanner to read the code and it says 7 emission tests are ready or something to that extend. When I bring it to a inspection station, they say they can't read the emission from the ODB interface. I said I just did it before driving there. They said this is not a scanner, but it's an emission computer. The guy also said maybe the cigarette plugs fail and he uses a light tool to test it. It wasn't on when the car is running. I take it home, use a volt meter and measure it. It's 14VDC. Which is a bit high. Is it unusual for this voltage? Apparently he didn't test the cigarette plugs correctly. What should I do? Bring it to a dealer? Could some car shop be able to diagnose and fix this type of problem? I don't have a good experience with this dealer, and the next Chrysler dealer is 45 minutes away.
Please help.
