Just hit 500 hours on my rebuilt 6.7 Powerstroke without a single check engine light, which is wild because the last one I did threw a code at 80.

Congrats on the clean run. My last rebuild made it about 300 before a sensor got weird. Some builds just come together right.

Honestly, that "sensor got weird" thing is the worst. Was it giving you random readings or did it just die completely? I had a MAP sensor start reading like 5 psi low for no reason, took me forever to track it down. Makes you wonder if it's a bad part or something in the wiring harness.

I had an IAT sensor die around 250 miles on one of my builds, but it was just that one sensor (a cheap Bosch unit). I don't think it's always the wiring though, sometimes you just get a bad batch from the factory. The sensor that went weird on me was giving random spikes, like -10 one minute then 180 the next, which made no sense for a 70 degree day. I'd say check the ground and the pin seating before you blame the harness, it's usually the little stuff that bites you.
