Where is the BMW E60 AUC sensor

Replacing the AUC (Air Cleanliness) Sensor
The AUC system sensor is built into the engine compartment. The AUC sensor registers the following harmful substances in the exhaust gases of gasoline and diesel engines:
- hydrocarbons (HC)
- carbon monoxide (CO)
- nitrogen oxides (nitrous oxide NO, nitrogen dioxide NO 2)
Even when buying a car, there was an error due to a malfunction of the AUC sensor. In the BMW e60, it is not collapsible, that is, it will not work to change the gas analyzer element itself. Removing it from disassembly is also not an option, because it is not suitable for 9/10 cars. It only comes in the original.
For a long time I tried to order the original for $ 60, but still the wish won that “Schaub did not turn on a single beetle” and “Schaub automatically turned on air circulation if KAMAZ was driving.
The catalog lists items 1 and 2, both of which are an AUC sensor. The second, as I understand it, for cars with the “S534A Automatic Air Conditioning System” is my case.
Got the sensor and installed it. It changes elementarily near the right cabin filter, next to it is the hood limit switch.
After the replacement, the error disappeared, but the smell in the cabin still comes from KAMAZ. I connected the input to see the command to close the dampers, opened the hood and pulled gas from the igniter to the AUC sensor; flaps closed immediately. So he gives the right command to control. But in real cases, when the exhaust gases go forward, for some reason it does not work.
Maybe I ordered the wrong position? It can be seen in people, it does not affect air quality. I'm going to fix this.

Where to connect the hood switch? something I did not see there a place to connect
the manufacturer realized that it was enough to measure the air quality in front of the filter itself, and not in the entire engine compartment. Well, the temperature of the filters is different, and there are no microparticles flying at a speed that would destroy the sensor. Live longer at rest.

The crankshaft position sensor (CKP or CPS sensor) is one of several sensors. This keeps your engine running smoothly. It measures the position of the crankshaft (which is why it is sometimes called a crank angle sensor or CAS). As well as the crankshaft speed (which is why it is sometimes called the engine speed sensor. ESS or speed sensor). The crankshaft position sensor transmits this information to the vehicle's on-board computer. Engine control unit (ECU). The ECU uses this information, along with input from other sensors, to control these systems. For example, ignition timing and fuel injection.
Thanks to this, all parts of the engine are well synchronized and work in harmony. The crankshaft position sensor is essential for proper engine operation.
How does a crank sensor work
There are several configurations of crankshaft sensors, but mostly they are. They work on the principles of magnetism. Many crankshaft position sensors are an electronic sensor. Known as a Hall effect sensor. The Hall sensor produces electricity internally when exposed to a magnetic field.
The crankshaft position sensor has a gear that rotates with the crankshaft. Interrupt the magnetic field. This creates an on/off circuit for the Hall effect sensor. What the ECU can interpret as crankshaft speed. The faster the sensor turns on and off, the faster the crankshaft rotates.
Whereas these Hall sensors give a digital signal. Some crankshaft position sensors provide an analog signal. However, they still act on magnetism. The sensor generates electrical voltage based on magnetic field fluctuations.
Vibrations are caused by the movement of metal pins in the crankshaft. Faster rotation means more oscillation and more tension. The ECU can convert this voltage into engine speed.
In any case, the timing elements, pins or teeth on the wheel must be located at the same distance from each other. To ensure accurate speed measurement. However, there is usually a corresponding gap. When the piston is at top dead center. This space allows the sensor to detect. Where is the crankshaft located, how does it rotate, as well as its speed.
Where is the crankshaft position sensor located?
The location of the crankshaft position sensor can vary from vehicle to vehicle. Obviously, it should be closer to the crankshaft. Therefore, it is most often located in the front lower part of the engine. It can usually be found mounted on the timing cover. Sometimes it can be installed behind or to the side of the engine. Sometimes the crankshaft position sensor measures the rotational speed of the clutch flywheel. Determine the speed of rotation of the crankshaft. In these cases, the sensor is fixed on the gearbox bell.
Like most details. Crankshaft position sensors can fail over time for various reasons. For more information on these reasons, check out this article on why crankshaft position sensors fail from the experts at 1A Auto!
