hello i finally got to scan my truck after putting the comp box on and the codes that popped up were 1690, 1682 0122 0238 0234 what happens if your map sensor voltage is too high because 0238 is that one? im worried about the code 1690 because it says fuel injection pump ckp sensor does not agree with ecm ckp sensor would the chip make it throw these codes the very first time i unplug everything and plug the wires for the comp box the first time?

 

Double Check All your connections.

 

what would cause the 1690 code?

would my connection being loose at where i tapped the pump would that effect anything? i got a stealth plate? but the nut seems to get loose? where it connects

at where i plug in the map sensor the plug in is a little loose where the edge connection snap in deal comes with is a little loose but its all the way in and has a little pop on deal.

what would also cause the apps code voltage to low?

 

Bad APPS
