I've only had the truck a few days but I am getting the infamous P0440 and SES light. New gas cap, reset ECM and got light back after 100 miles or so. Reading, I suspect it may be the vent valve or the vent valve solenoid. I found the thing above the tank and under the bed. My hands are way too big to try to do anything with it there.
Is there a "how to" on the test and or the replacement of this thing? I am assuming raising or removing the bed may be the best answer?
Thanks,
