I have an '04 S Blazer 4 door with 47,000 miles that sets DTC 0455. I've changed the gas cap with 2 new caps (Stant locking type) code still sets. Short of pulling the canister out and inspecting "everything" what is the "usual" trouble found?? I was going to inspect the vent valve first, then the purge solenoid on the intake manifold, then the canister. One other thing, a year ago the vehicle was hit in the left rear side. The body shop replaced the left rear door and the left rear quarter panel. I don't think the canister was involved, but the filler pipe may have been. Sooooo.... what do you pros see as the most likley failure piece in the EVAP system??? I find it hard to believe a loose hose in the left rear (canister / fill pipe) area took a year to show itself.
