I didn't know if I should post this in the "Help section". I'm not on the side of the road, my truck is still running, It's just the check engine light. There are 2 codes, I'll erase them and the check engine light will stay off until I really step on it, "WOW", then the light comes back on, Erase and the truck drives OK, the light will stay off until I hit it hard, even towed my 5er last weekend and the light stayed off, checked for codes and nothing, went to work Monday and put my big foot into it and the light came back on, same 2 codes again.

I'd say first to check connections at the map sensor on the intake manifold. Check the related wiring as well. IIRC the Commander plugs in there and could have a poor connection. Also make sure that the XZT is plugged in to the right side so you are getting boost fooling. SHould have the commander plugged into map, then xzt plugged into the factory plug, and the other side of cammander should go to the other side of xzt. Did that make sense? Lot of plugs!

 

Unless of course you have yours wire tapped. Then all you have is the xzt plugs at the map sensor.

 

OK, now I 'm really confused. I did have the XZT out when this all started last week, had it updated, just put in back in last night.

 

Unplug the Quad stuff and see if the code comes back.
Also could be a bad connection on the MAP sensor or the MAP sensor itself.

I know this isn't the place to ask this question, has nothing to do with the codes, or maybe it does, when I plugged in the updated XZT and set the Commander setting I set the Commander for Xzillaraider XZT, because th is no setting for ether updated Xzillaraider XZT or Xzillaraider XZT 2. Oh yes, now I 'm really confused.

 

This sensor is on the intake manifold held in with two small torque screws. Remove the plug and check out the first pin on the right. (black/orange). There is a defect in the plastic that did not allow the pin receptacle to go all the way into the plug. Therefore the receptacle is “sitting” on top of the sensor pin. I had to cut the plastic defect out to get the pin receptacle to seat. Did not affect the plug seal. All better! No more codes and back to hauling butt!
