Anyone come across this condition (02 Sensor Bank 1 Sensor 3 No Voltage Detected)? I read this value on my Torque app. This seems to point to the O2 sensor on the aft portion of the cat. This is a California vehicle if that matters. The reason I was looking for errors is that I hear what I can best describe as pinging when accelerating through about 45 mph. Its not too bad, but its new for sure (not to mention annoying). No noticeable loss of power or any loud noises to go with it. I don't have any codes though, and based on a few searches, it should throw a code P0146.

Its got a fresh oil change right now. 100,000 miles mark just passed. I don't know if the spark plugs have ever been changed, so that's a job I'm trying to pump myself up for.

Any ideas or past experiences would be appreciated.

Thanks,
Bob-
