Engine light came on but truck is running fine any suggestions

 

You check for codes yet?

 

Yup! First step is see what the code is

 

ok so i got 3 codes. and an egr delete kit for starters.
code#1
p0401-was told insuficient egr air flow.
code#2
p0404- egr feed back out of range?
code#3
p0181- fueltemp signal out of range?
i was told eger delete kit should solve the first 2 but what is the 3rd one? one guy told me i need to have gm flash my ecm to clear the code. but why would my fuel temp signal b out of range? stock d-max just under60k in mileage. let me know what u think.

 

there is a tsb for the p0181 code iirc, i know the ecm flash wil fix it.

egr delete and tuning will take care of all three
