got the 0238 map voltage high and 1689 ecm not communicating with vp. truck runs but feels like it is starving for fuel. any help is appreciated.

 

try replacing your fuel filter. please fill out a signature so everybody knows what truck you have. may help you get a better answer. need the year, engine, tranny, stuff like that.

 

sorry about that, i thought i checked off that box. the things i tried: unplugged and replugged the ecm, reset the apps, unplugged and replugged the plugs going to and from the map and fms, samething for the vp w/no luck so far. i didnt try hooking the oem harness to the map to see if the problem is in the fms, but the fms has been turned off since the first sign of trouble.

i did give the stealer a call and the sensor is $164 and they say i have to by a pigtail for $35 and replace the exsisting flat plug. problem is the fms intercepts the signal from the map and fools the ecm, so i am not going to cut that plug without voiding the warranty from bluechip. i put a call into chip to see if they have some kind of adapter to go from the new round sensor to the exsisting wiring. he should be getting back to me on monday. if worst comes to worst, i will make my own adapter by purchasing the male round pigtail and a flat female pigtail.

i will update on monday
