EGR and O2 fault codes
2008 ram 2500 6.7L Cummins. I recently got this truck and really like it. I suspected that it hade some kind of tune on it but wasn’t sure. I hooked up an edge evolution to check everything, and put it into tow mode to see if there was any noticeable difference. Now I’m getting some codes that I cannot clear. I put it back to stock but they still will not clear. I’m getting p0487, p0037, p0031, p2141. So my question is, if there was something hooked up before, how can I go about putting it back the way it was? Do I have to get a tuner with the delete stuff or, if I know someone with a tuner, can I use that on my truck just to put it back?
Did you overwrite the tune that was on the truck? Your programmer should have saved what was in there.......
Do you still have the EGR valve, and associate hardware on there? Is it all hooked up?
P0037 is for the O2 heater control circuit. I *think* that circuit controls the relay that supplies power to the heater circuits. (but, not 100% sure on that.)
P0031 is same problem for another O2 sensor.
P2141 is another EGR code.....
