Electrical Issues

[yekrahs]

Alright well my buddy has an issue with his car and I was just trying to get some input to see if anyone has had this issue before. He was messing around with his rear o2 wires and they sparked (must have shorted) and his car started running like shit. If you look in a diagram two of those wires are connected to various things such as crank position sensor, cam angle sensor, etc. We have tested the cas with buying a new sensor and we are going to try to eliminate the coolant temperature sensor today. My question is before we have to test the crank positioning sensor is there anyway to test everythign else that comes into contact with the rear o2 wires? Let me know thanks!

Some of the Rear o2 wires touched, probley positive and negative, or heater + positive, this results in a trace being blown in on the ECU, give it a look, the blown trace was as clear as daylight.
Hope this helps.
