its the o2 sensor before the catalytic converter on the drivers side I believe


It's the oxygen sensor before the catalytic converter on the side of the engine that has the number two cylinder on it. It's the side closest to the front of the vehicle. Standing on the driver's side facing the vehicle it's the left side of the engine. Hope that helps! Jim
