The oxygen sensor installs in the upstream position on 2000-2002 Honda Accord, 2001-2003 Honda Civic and 2001 Honda Odyssey. It signals whether the exhaust is running rich or lean so the engine computer can trim fuel delivery. A built-in heater brings the element to operating temperature quickly after a cold start.
