[QUOTE="Mark Price 2, post: 1018973, member: 70403"] Easiest thing to do first is to visually check wiring for corrosion or frayed wiring. Common for O2 sensor wires to rub threw the insulation and short to the frame. Also common, if it has been replaced before, that the "spliced in" wiring on a aftermarket sensor has corroded or rubbed through(or poor work). Listen for an exhaust leak as well while your under there. Around the flex pipe. Very common for that pipe to get damaged. My wife used to hit it on boulders or something all the time in our old honda.:) Be safe. Jack and jack stands required!!!!!!!!!! Cross your fingers way: replace it yourself and hope that was the issue. Best way: diagnose with a scan tool that reads live data. [/QUOTE]
