Re: P0442: EVAP system small leak detected
Were it my truck, I would inspect the gas filler cap. Look for dirty components such as the end of the filler neck and the seal on the cap. Check that the cap is tightened when it starts to click. The clicker thingy can get weak, and click when the cap is not really tight.
If you have(I don't know when they started) a 'capless filler' system, check on youtube with makuloco about cleaning the capless system. Apparently they can cause a similar code when the gizzards get a buildup of crud.(tech term, I'm sure)
A 'small leak' is generally something like the cap or a vacuum/vapor line that is slightly loose, not a major component. Check the cap, watch some youtube, couldn't hurt...
