    Thanks in advance to any suggestions.

    2013 Tundra SR 5.7 4x4, 75k miles.

    I'll try to make this short. I had to replace the wires for the crankshaft position sensor (rodent got to it). Ran fine but a couple months later started to shut off on me. Found a broken wire at one of my crimps, replaced it, but still had issues with a small 2 inch piece of wire coming from the ecm connector D74. The slightest wiggle of that wire (pin 110 on the D74 ecm connector) would cause it to stall out. I pulled the pin, replaced it with a new pin and new wire. Truck will now start and run (not drive) but I get about 18 codes for high voltage on pretty much every sensor you could think of. Any suggestions?

    Had voltage codes once on. Toyota Tacoma. Doesn’t seem to be the same issue.

    Someone with a bigger brain than me will chime in. But my first thought is are you sure you put the pin in the right spot, or is that pin shorting out somewhere? If that pin is the 5V output for the sensors and maybe it's picking up 12V from something else I would think it would do what you're saying.
