03 WJ O2 sensor prob
I have an issue with the upstream oxygen sensor. I took it to a mechanic and he ohmed out the sensor said that it was not bad and checked the power to the sensor and said it was good. He suspects that the wire from the sensor to the computer has a short in it. Causing the check engine light to come on and the fuse under the hood keeps blowing any suggestions?????
