Okay, here is where it is at, I still have the O2 sensor code. I have cleared it a couple of times and it always comes back. I haven't gotten the rich/lean code today.

I tested the new sensor and got a around 0.57 volts, so based on that, the sensor seems to be alright.

I tested the connection to the ECU. With the sensor connected, I am not getting continuity. The Bentley book says I should. When I tested the wire from where the sensor connects to the ECU I do have continuity so its not in the harness. There is a good ground from the Cat and at the body of the O2 sensor.

Is it a bad sensor? I am getting the correct voltage reading with the engine running but not continuity.

help please.

Thanks
