Hi guys, I hope this gets answered here. Bought my Ram 1500 2004 hemi couple months ago. At the time I was told the EGR was bad so they replaced it (dealership I bought it from). Code went away, but after a couple weeks got the check engine light again. Took it back, and the guy checked it and said it was the gas cap ( i think he was wrong as I saw a PO406 code on his reader). Replaced it. Couple weeks back again.
So I get a code reader and it is the PO456. EGR issues I guess. Weird since they said they replaced it. Maybe they didn't install it right. It actually shows two codes. This is what the reader says:
PO456 cnf mod10 (very small leak)
PO456 pnd mod10 (very small leak)
Truck doesn't have any symptoms, other than not great gas mileage around town. According to the OBD comp it is around 12.8mpg highway and street.
Does anyone know what the difference is in those 456 codes? I read the EGR can throw at least 4 different codes. Hoping to fix this on my own as I don't really trust this dealer anymore and I do everything myself anyways. Don't want to just start throwing money at it and replacing the egr before I know what these two 456 codes mean. thanks for the help!
