my 2002 california 7.3 through a P0475 when I started it after being parked and ignored a couple weeks :-/
it seemed to run just fine, but I only went down and back up the mile hill I live on twice, once down and up with my trailer, and again down and up without it.
I gather this error is something about an Exhaust Backpressure Regulator aka Exhaust Pressure Release Valve, and that valve is somewhere on the turbo pillar. It was too hot under the hood to investigate so its cooling off now. While I've had some rodent wiring damage in the past, I didn't see any fresh signs (no piles of branches or acorns or poops.)
