TONS of SES codes help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!
heres what they are, car ran for under 2mins in park and these are the codes i got on datamaster, the car runs so bad, its not the pcm nor any of the sensers, everything is pointing to the electrical side of things
MALF 78: Fan 2 Fault ,
MALF 16: Lo-Res Fail ,
MALF 67: A/C Press Sensor Degraded ,
MALF 84: 3-2 Downshift Feedback Fault ,
MALF 97: 4000 PPM VSS Circuit Fault ,
MALF 55: Fuel System Lean ,
MALF 24: Output Speed Low ,
MALF 29: EAS Electrical Fault ,
MALF 64: Right O2 Lean ,
MALF 37: Brake Switch Stuck On ,
MALF 52: Oil Temp Low ,
MALF 41: EST Open ,
MALF 27: EGR Electrical Fault ,
MALF 24: Output Speed Low ,
MALF 29: EAS Electrical Fault ,
MALF 13: Left O2 Fail ,
MALF 82: Shift A Solonoid Fault ,
MALF 95: Oil Life Lamp Circuit Fault ,
MALF 37: Brake Switch Stuck On ,
MALF 63: Right O2 Fail ,
MALF 80: Transmission Component Slipping ,
MALF 22: TPS Low ,
MALF 50: System Voltage Low ,
MALF 25: MAT High ,
MALF 71: A/C Evap Sensor Failed ,
MALF 12: No DRP Pulses ,
MALF 64: Right O2 Lean ,
MALF 81: Shift B Solonoid Fault ,
MALF 53: System Voltage High ,
MALF 63: Right O2 Fail ,
MALF 80: Transmission Component Slipping ,
MALF 22: TPS Low ,
MALF 50: System Voltage Low ,
im guessing this is something electrical, any clue?

I hope that there is something wrong electrically for your sake. Otherwise, that is a lot of crap to replace. I just had like 5 or 6 codes show up at once and i thought that was a lot.

Yes, but some of them have nothing to do with electrical...although the sensors send data electrically to the PCM.
I think you might have a major short, or loss or power somewhere after your battery/alternator.
It might be triggering a shitload of sensors, or throwing them off.
Does the car run?
When did it start doing this?
Maybe a rodent got in there deep and chewed some wires?

What year car is this? If it's a 93 you can pull the chip and the car will run in "Limp Mode" which is really, running like TOTAL *** lol Literally, you limp it to where you need to go. I don't know what 94+ can do for close to the same thing

So this happened after you changed the water pump? If you scan the car, do they all come back? For the voltage issue, I have seen a really low battery make a car throw ABS codes because it didnt have enough power to operate the hydraulic unit.

Check the grounds by the coil driver and on the side of the block by the dipstick tube. pull on the wires about an inch back fromt the ring terminal to see if the wire broke in the insulation. If not gm pcm's pull this **** when they frag.

Well, i took the TB off and cleaned the IAC and added a new gasket, when i took the TB gasket off was missing a peace, i can not believe that having a vacuum leak would throw all these codes, anyway after i put it all back i started it and it idled fine and ran great, confused so plugged in my data logger in and started to log, i now get constant a MALF 22: TPS Low code, and i see that my Lterm count is at 134 at idle and when in gear both L,term counts are 142 , 135 and those pretty much stayed the same the whole run, and the S,trem counts are around 108 - 128,

i checked it on the data log, right when i turn the key on with out the engine running it thorws the low TPS code, but it sits at 0.61 volts 0.0% open, and i push the gas and the volts move up and so does the TP % , so whats going on?
