Far from this regime, the catalytic converter will be unable to break down nitrogen oxides. The NOx sensor detects the level of nitrogen oxide in the exhaust gases. Continental Nox Sensor How To Diagnose AndThis article explains how to diagnose and replace a faulty NOx sensor in an E87 1 series BMW equipped with an N43 engine. It is probably mostly applicable to other similar models, including some 3 series. The sensor is reasonably accessible and so it is suitable for DIY replacement. Modern BMWs are equipped with an on-board computer which controls the operation of the engine. One of the roles of the DME is to reduce emissions of polluting gases and reduce fuel consumption by controling how fuel is injected into the engine. In order to do so, it relies on data supplied by many sensors. Several of these sensors are installed in the exhaust pipe and one of these is the NOx sensor. By controlling the amount of fuel injected into the engine, the DME can vary the ratio of fuel to air. There exists an ideal ratio of air to fuel such that there is just enough air for the fuel to burn completely and no more. We call the air-fuel ratio (Lambda) and define a scale such that 1 is this ideal ratio. If the DME injects less fuel, such that the air-fuel ratio is higher (1), then we say that the mixture is lean. If there is more fuel we say that it is rich; see Air-fuel ratio (Wikipedia). If the fuel mixture is rich, then there will be unburnt fuel present in the exhaust. If the mixture is lean, there will be oxygen present in the exhaust gases and these gases will be cooler. The engine will also deliver less power than when it is running at 1. However, this power is only really useful when the car is accelerating hard or driving on the motorway. When driving is town or queuing in traffic, we only need a fraction of the power that the engine is capable of delivering. It is wasteful and causes unnecessary pollution to keep the engine running at 1 when were not fully utilizing it. Therefore, in order to reduce fuel consumption and emissions, the DME orders a lean fuel mix. Unfortunately, there is a problem caused by running a combustion engine at 1. A side effect of the combustion of the fuel in the engine is that the intense heat causes nitrogen in the air to combine with oxygen to form various unstable compounds of nitrogen and oxygen: nitrogen oxides. Fortunately, as these compounds are unstable, it is easy to break them down into harmless nitrogen and oxygen. However, a catalytic convertor operates most efficiently when the engine is running at 1; see Catalytic converter (wikipedia).
