My car is FWD and I don't know what kind of sensor I have change but tel me about both
Expert:  Joe replied 8 years ago.
OK. There are two sensors, one under the hood in the exhaust manifold(upstream) and one under the car in the catalytic converter(downstream). They are both simple to replace. You need to unplug the connector and use a 7/8" wrench or more likely an oxygen sensor socket turn them counterclockwise to remove themThe downstream one may take a little longer to replace due to the fact that the plug for it usually goes up into the floor-board, and you need to pull back the carpet on the passenger side front to unplug it.graphicgraphicgraphic
