gas cap
#21
The test software (if this applies to the region) would read which OBD monitors are supported by the PCM, and which of those are Complete (aka set aka ready aka passed). Some regions allow 2 or 1 not to be, but many require all those supported to be complete (as well as no codes).
Currently it's a pathetic visual check of MIL here, with tailpipe gases tested.

Jagman, the smoke test was the 1st thing I had done but my mechanic said they could not find a leak. He suggested starting with the gas cap as it is a replacement, not OEM.
Tbird6, I've checked the canister but no hissing noise. I went so far as too take it off and visually inspect it. I saw no cracks or sticky dried gas. Hoses are in good shape as well.

There must be a leak, have it smoked again! Try and do it on nearly empty tank of gas. In my experience smoke testing when done properly is a reliable test. The Cannister Close Valve has to be commanded closed with a scanner, and then watch the flow rate on the smoke machine gauge to gauge the size of the leak. (A 0.040 leak is significant). A bad cap will show up with smoke. If there is no flow then the purge valve becomes suspect (depending on how and where the smoke is being introduced). I believe your car has a port for testing.
Good luck!

If you cant find it in the glove box then try under that ginormous pile of stuffed animals sitting on the rear package shelf ...
