Everything you need to know about Oxygen Sensor! http://www.bmwe36blog.com/2007/07/02/everything... The Oxygen Sensor is usually to blame for problems in the car performance and gas consumption. It s stunning to discover that it s hard to fail. I can count many of my friends who went to mechanics for car checkups and ended up changing the Oxygen Sensor.
The reason why the engine needs the oxygen sensor is because the amount of oxygen that the engine can pull in depends on all sorts of things, such as the altitude, the temperature of the air, the temperature of the engine, the barometric pressure, the load on the engine.--------smithsanUsed Cars+REPLY?
