Checking an O2 sensor
My mileage has dropped off recently and have seen you guys point to the O2 sensor in the past. Is there any way to check this with a voltmeter? What kind of voltage reading is too high/too low? :confused:

Best thing to do is to just replace them, as they are cheap. I replaced all 3 of mine at 80,000 miles and saw an instant increase of 2 MPG on average. The old ones were coated with build-up. I have read to replace them at around 60K-80K miles.

Oh my god man, you don't listen do you? Replace the foolish thing. It costs $30, and if it hasn't been done in a long time, it should be done anyways. Go to autozone, borrow the O2 sensor socket, put on the new one (which already has the sealent on you), and return the socket.
