That’s FANTASTIC! Now if we can get an alternate source for the DEF heater/ pump it’ll be great.
Now, that Dorman sensor- did it come with a module? Or was it just the sensor like you’d get a gas engine O2 sensor?
I would be a little more excited if he was able to clear the count down timer and move on. That's the real test. The one I couldn't get by when my DEF injector went TU.
