Help/Advice on Diagnosing Error Code P0442

[BigRogers]

Hey guys,
Long story short I had some work done this time last year as my CEL, VSC & Trac Lights were on (Code P0440). I ended up replacing my PCV Valve, VSV (Vacuum Switching Valve), charcoal canister, and pressure relief valve (gas tank). Some of the work I did, some of it the shop did, but it worked no and more CEL/idiot lights.

Drove the truck for roughly a year and now the CEL, TRAC & VSC lights are back on :rant: (Code P0442). I need help/advice on how to locate any leaks in the system. I was going to give soapy water in a spray bottle a shot, but beyond that I am pretty well stumped. PLEASE HELP!!

Make sure your gas cap is tight. Might try buying a new one if yours is really old.

Checked that out as soon as the lights came on. And it was the first thing I replaced when the lights came on last year, it was original to the runner.

Here's the link to the FSM. It gives steps of what to check. I have no idea if the steps are in the best order for the most common failures. I haven't dealt with this before. Maybe someone else will chime in.

Getting this code popping up every so often.
