Ok fellas here what I got. Its throwing codes for MAP sensor, TPS, and ECT sensor too low/hi. I start checking around and what do I find? 43 volts on my voltage reference wire. What the hell happened?

I checked it at the pin and sure enough, 43 volts. Ive never seen an EEC fail and read high, all the junk ones I've ever seen read low. Am I missing something?

when you're reading the 43volts is it with the engine running or just koeo?

do you have a capacitor or some other power source somewhere on your truck? i'm trying to grab some theories on how you could get more than 12v.

Thats what was blowing my mind. I know voltage is regulated in the computer but I was unaware it had the ability to increase voltage. The only thing I can think of is shit being all corroded and somehow criss-crossing itself to create extra voltage? 12+12+12+12=48 right? I'm stumped.
