While i was driving to work this morning my truck compltetly shut off and went into fail safe mode. Could my programmer cause this??? My programmer causes my check engine light to come on but no codes are thrown. I have a DAS DAQ programmer. After about a hour and a half i was able to start the vehicle and drive it to the dealership. While driving to the dealership the truck drove fine. The dealship advised me to run tyhe truck without the programmer plugged in. Did that for about 50 mi with no issues besides just having stock performance. I am new to the diesel world and any advice or help would be greatly appreciated!!!!!

 

My guess would be an EGT sensor detected it was getting hot. What kind of programmer?

 

I have no clue. I have a DAS DAQ screen. My gauges were reading good. I bought the truck with the programmer on it. The programmer always throws a check engine light. But when I check it. Nothing comes up. What u think might be the issue????

 

what kind of programmer?

 

Spartan I'm guessing. I bumped up my program to 125 and it threw the P041D code.

 

And is it common the more horsepower u put on the higher u idle???

 

you need to call spartan with your vin and find out what is going on.

 

Also according to my egt gauge I'm idling at 800 deg.

 

That is not normal
