Hey guys, first time posting and i need some help, Im working on troubleshooting a buddies 2016 ST and its throwing P08AA and sometimes some other low voltage codes as well. He already replaced all three clutch sensors, slave cylinder and I bled the system. I've checked grounds, traced all the wiring to the sensor, which is the one behind the battery box and all three wires wind up at the PCM. I checked continuity through all three and they all show 0.0 ohms and I have 0.1 v of voltage drop. As soon as i plug the PCM in and follow the pinpoint test i have voltage on the CPP wire when it says I'm supposed to have none, and i have nowhere near the specified resistance on all three wires. (2600 ohms) workshop said it should be 10k or more for this test. When i checked reference voltage it asked for 4.5 to 5.5 volts and I got exactly 5.
As far as PCM condition goes from a visual side, its corroded, the CPP wire enters at the spot with a ton of corrosion, the box its stored in is not sealed anymore and the fender liner is missing. I'm pretty certain that that is my problem but i wanted to ask for more opinions as all my tech friends wont even touch the thing or offer any advice and i need to come up with a solution soon.
this car has also had some other work done to it, and it just had a stock motor put back in after being big turbo tuned and built, and its having some other quirks here and there that also lead me to think that maybe the tune was never completely erased.
Questions, Comments, I'll be waiting for them!
