What code(s) are you getting?

 

i haven't hooked up to a code reader yet but did you have this issue as well? what codes did you get?

 

I had P0420, then I bought the URD emulator.

We really need to know the code(s) and go from there.

 

If ur running longtube headers, its most likely a p0420 and p0430.
But step 1 is FIND OUT whats causing an early xmas.

Then call gadget at urd and find out if they have the fix for 2015 trucks. After a certain year the 02 simulators did not work as well as they should.

Extension #3

 

Ya sorry I am getting both the 0420 An 0430 codes I just received the urd extension for the front sensors idk if that will work my truck is a 15 An I've read it's hit or miss the the urd simulator

 

Mostly miss with the 15
