    After a mouse had chewed though my 3 crankshaft sensors, i was able to reconnect the wires. It ran for a couple months, it shut off on me, I found a break in one of my wires, repaired it and now it still will not start. Ive removed all crimps and used solder sleeves to prevent any future breaking. Long story short, I'm now left with these 4 codes.

    P0338 Code: Crankshaft Position Sensor “A” Circuit High Input

    P0343 - Camshaft Position Sensor “A” Circuit High Bank 1 or Single Sensor

    p0348 - Camshaft Position Sensor ‘A’ Circuit High Bank 2.”

    p0368 - Camshaft Position Sensor “B” Circuit High (Bank 1)

    I'm no expert and mostly everything I've checked was based on Google searches, but I'm stumped right now.

    Reference voltage is at 5.05V.
    All signal and ground wires have less than 1 ohms.
    Crankshaft sensor has been replaced.

    Continuity has been checked bewteen ecm connector and sensors.

    Welcome to the club.. I'm trying to solve a similar issue, except no mouse ate my wires... So it's either heat soak from somewhere or a legit broken wire inbetween the ECU and all 6 sensors, yes 5, the crankshaft position sensor. I've swapped this one out and still has the same issue. Mine turned to a P0010 now.

    The only 3 wires that were chewed were the three from the crankshaft position sensor. As of now everything Is as close as possible to original. But all I get is a crank/no start.

    What throws me off the most is that it ran for some months after I originally fixed it, and then stopped running after repairing one of my broken crimp. I narrowed it down to the signal wire (pin 110 on the ecm), wiggling the first 2 inches coming out of the connector would make it start/shut off. I put in a new pin/wire from the ecm and out several inches, but now only cranks and won't start.

    Originally I didn't have any codes at all. The crankshaft sensor code came up recently after I unplugged it and the camshaft sensor codes came up after disconnecting the ecm connector.
