Anyhow... code reemerged. Smoke test planned... by June 22025.  |
Hey Starter986, I've been having this same recurring issue with my 986 (same year as yours
). I've replaced the fuel pump, that seal ring you were talking about, the bleeder valve on the filler neck, changed out the gas cap, even the regen valve on the throttle body, and I've also done a smoke test.
Nothing. The CEL for P0455 still comes back every time after a little while. Smoke test came up empty.
Did you ever get a chance to do a smoke test? Or were you ever able to solve the issue?
