I'm in trouble guys. MAF TB AAP ECM>>
I'm in trouble guys. MAF TB AAP ECM>>Let me start off by say thank you face.. I have faith this might help me out..
Just got an 02 max auto ( I'm learning there wasn't too many variations this year,,, well except for mine )
I couldn't turn it down. 125k, mint in and out. But the engine compartment was never washed. So i washed it. Like I did with so many cars before it.
And this is where the fun starts.
Moments after the wash I decided to add a lb.of 134a. Had my buddy jump in the front seat to get the low side down and he says " I GOT NO PEDAL"
Huh?
First it threw codes for TB. Replaced it.
Then it threw MAFS. Replaced it.
Then it threw codes for APP. (both 1 and 2)
Still nothing.. Keep in mind this hole time Im doing the pedal dance. Dead shorting terminals You name it,, I tried it.. At this point I'm like " F**k all this s**t. I'm getting a new ECM and sending all this stuff back" 2nd ECM comes (and with the new parts still on) I get No codes and I'm still locked at 1300rpm. Cant reset the ECM and it don't even flinch when I smash the pedal.
Well now I'm pissed..This thing ant gonna win.
Bring on the values.
I got 5v.at the TB. Solid ground but no pedal flip flop variation in voltage. At the APP I got my 2.5v at (64) and my 5v at my (111) solid ground and pass thru the sensors seems to be fine.
Which leads me to why I'm leaving this post. I appear to have a different harness then whats in the 800 PAGE.ENGINE CONTROL SYSTEM MANUAL.
I checked the 01 02 03 04 and nothing matches up,, colors,, values,,.Nothing..This is preventing me from checking continuity and values at the ECM. I hit a wall
I will drive (push) this thing off a cliff before I rip the dash out and make my own wire harness..
!st Q: ignoring the fact that my colors don't match do I need to keep the ECM plunged in and back pined to get these values?. I only get the values at the APP and TB with it plugged in. and even with it unplugged I'm getting 13.5 volts(%200) at 74. I know that ant suposta be there..
Please help.. Ive got to be missing something...and I'm sorry this is a hard question. Hoping someones up to the challenge.
