Hello all, I recently bought a g35 that was wrecked as a project car. I have scanned it and the codes that appear are(in order) p2122, p2138, p0643, p0183, p0447. I already know that there is a short/open circuit and I wasnt sure where exactly to start. I have researched all the codes and p2122, p2138, p0643 all have to do with either the accelerator pedal sensor not working or there being a shorted harness or a circuit with poor electrical condition. Should I replace the accelerator pedal sensor or start by checking the circuits? Thanks.

Grab a multimeter and a notebook and have fun. Spend some time checking the wires, keep track of your steps. Then if you find nothing, you could then replace the sensor. Just my opinion though.
