BMW E4. 6 Oxygen Sensor Replacement BMW 3. BMW 3. 25. Xi 2. BMW 3. Ci 2. BMW 3. 25ti 2. Oxygen sensors are used to monitor the oxygen content of the engine exhaust. That information is used by the engine control module to fine tune the amount of fuel supplied to the fuel injectors. In the BMW E4. 6 6 cylinder engine, a pair of oxygen sensors is installed in the exhaust manifolds just ahead of the catalytic converters and another pair is in the pipes just after the converters. Once the engine reaches operating temperature, output from the precatalyst pair of sensors settles into a steady wave pattern between 0 and 1 volt. The lower limit indicates a lean fuel mixture extra oxygen in the exhaust, which the ECM corrects for by increasing the fuel supply. This leads to a richer mixture low oxygen content in the exhaust and a higher voltage produced by the oxygen sensor the ECM then reduces the fuel amount and the cycle continues in this fashion, producing what is called closed loop operation. Matt Comments I have a 2004 BMW 330CI. I am getting fault codes 2716 oxygen sensor heater after cat conv bank 1 activation, 2882 fuel trim bank 1, and 2883 fuel. The post catalyst pair of oxygen sensors ideally detects a steady and unvarying amount of oxygen exiting the catalytic converters. The ECM uses this information to monitor catalytic converter efficiency. Oxygen sensors should be replaced every 1. In a perfect world that would be it, wait until a specified mileage and replace the sensor. However, these sensors fail prematurely, set off oxygen sensor fault codes and reduce fuel economy. In this article, I will show you how to identify the location of all four oxygen sensors and how to replace them. You will need an oxygen sensor socket to remove the sensors. Remember to always work with a cool exhaust. Oxygen sensors are fragile. Do not drop one or damage may occur. Also, keep the sensor tip clean when reinstalling. Oxygen sensors are laid out in banks, which refer to cylinders and in sensor numbers referring to before or after the catalytic converter. Bank 1 or B1 refers to cylinders 1 3. Bank 2 or B2 refers to cylinders 4 6. Sensor 1 or S1 refers to the sensor before the catalytic converter. Sensor 2 or S2 refers to the sensor after the catalytic converter. Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches.
