I just took out my edge comp box and replaced the vp44 on my 2001, now its throwing codes. These are the codes P1475, P0343, P1286, P0123, and P1693. They all seem to be related to high voltage, did I miss anything that comes to mind for anyone. Any help greatly appreciated.

High voltage codes mean open circuits. The pcm will send out a regulated voltage of usually 5 or 8 volts to the various sensors then monitors the drop with an internal volt meter. When a circuit is open or a sensor is unplugged the supply voltage is not used up by the sensor so the voltage is "high". Turning the key on without everything plugged in will set this type of fault.
