    I've read around and found out the info about the false loose gas cap CEL, and see that there is a TSB on it which shows the fix as relocating and replacing the EVAP sensor near the gas cap. Has anyone had success with cleaning the existing sensor or even replacing it with the original part (it's about $50 as opposed to the $400 the TSB fix cost)

    with 160k on my 1500 I doubt the dealer will relocate and replace everything for nothing.

    Could you share this TSB with us? What year is your truck? What is the specific code? There are several EVAP codes. Thanks.
