dougall42 Posted January 12, 2012 Share Posted January 12, 2012 My OBD reader tells me that I have "Evaporative Emission Control system leak (small leak). P0442 Anyone else had to trouble shoot this? Link to comment Share on other sites More sharing options...
Autoevo Posted January 12, 2012 Share Posted January 12, 2012 Have you checked your gas cap? I can't remember if there was a specific code for gas cap but in years pass a bad gas cap or a gas cap that wasn't tightened all the way could throw that code.

chutrain Posted January 12, 2012 Share Posted January 12, 2012 The most common is the gas cap. The vacuum leak has happened to me as well on another car. Link to comment Share on other sites More sharing options...
dougall42 Posted January 13, 2012 Author Share Posted January 13, 2012 Thanks for the feedback. I thought of the gas cap, it is tight but I've got 312,000km on the car and maybe its time for a new cap. Failing that I'll start going through the vacuum lines.
