Dave,
I was told to do a test last night to check the heater on the sensor to see if it was heating properly. I turned the key to the "run" position for at least 30 seconds, and I was told to touch the body of the sensor for some heat. I did that and the sensor was still as cool as it was when I moved the key, even after about a minute with the key in that position. I made this test twice with the same result, so I pulled the sensor. The sensor does have carbon on it, but like yours, the holes are not covered and it can wipe off.



Note: I do not have any power on check routine unless it is built into the FAST system. I run unleaded pump gas and the sensor is plugged in full time. I may have just gotten a bad sensor.

Thanks for the reply.

UPDATE:
I talked with FAST tech support and I need to ship them the unit back for full inspection. It looks like I am out of the O2 game for a while.
