Question, your p0222 diagnosic says on step one, if greater than 4.5 volts, go to next step. If voltage is 5.5 volts or less, go to step 8 . Mine is reading 4.7volts on both pin 2 and pin 6.

 

So I would go to the next step.

 

Ill do that tonight, but drove to wok this morning now I have p0122 p0222 p0236

 

P0236 is basically stating that the MAP sensor is stuck at a high value and not changing. So I would guess the MAP sensor is done or there is a electrical issue.

P0122 and P0222 is pointing to a failed APPS most likely.

All my diagnostics are here...

I understand everything your saying just asking before I go do all the wire chasing is a bad map sensor or bad apps or both combined going to cause no power and all that? Or limp mode as you say

 

I suggest doing the testing and wire chasing before buying any parts. testing is cheap but parts are expensive...

 

Well I took my apps sensor off to check the connections and now it won't read any voltage when I turn the key on hook my dmm to negative and positive to the wire coming out of computer not getting any voltage while turning throttle so it's junk I guess

 

I hope your doing that right because that would mean the ECM is junk because the APPS sensor doesn't create the power the ECM does... Double check what you doing.

 

No what I mean is when you unplug the apps sensor plug i still have voltage going to it on terminal 2 and 6, im saying i plug the apps back in and i still get .0498v or something like that? and doesnt fluctuate when i spin the throttle either. first time i cleaned it i would spin it and at certain spots i would get a reading of like 1.2359v or something then it would stop and go back to some random voltage

Plugged it in again after work.. Now it works fine

Sorry ive been jumping around but I think I figured it out if you could get back to me, forget about the apps yes i know its going bad but its working anyways the no power issue, i found out today if I plug in my map sensor harness just fatory regular old harness it goes into what im calling "limp mode" and wont let it go past 2k rpm's in drive. BUT I tryed this I unplugged the sensor completly? AND it runs shitty but it runs! So does that mean the sensor is stuck open at a high voltage setting the computer into a limp mode or a protection type thing?? What I mean by it runs when its unplugged is i can actually go the speed limit unlike when the sensor plugged in i cant go past around 35mph.
