Right Heated O2 Sensor Harness Location?
Hey guys,
While under the car today, I noticed that my right heated o2 sensor cable was just hanging to the side (lol, that explains the repeated cases of CEL and 8mpg). Anyways, I spent a good hour trying to find where the sensor plugs in to, and I was not successful. Where is the plug in located?

Mine comes off the ignition coil which is located in front of the passenger head or just under neath front of the valve cover. Basically the heated O2s need a unswitched 14v source of power. Maybe try following the wires up from the driver side O2 to see were they go. There are other power sources to use, so yours maybe be using something different. Try looking down past the exhaust manifold for the wire harness on passenger side. Its got to be there. It should have a plastic adapter coupling at the end of it to attach the O2 end to.
