BMW e36 sensors - complete list

The correct operation of the sensors greatly affects the operation of the car. If, for example, the camshaft sensor is out of order, the car will start, but will not respond correctly to pressing the accelerator pedal. But if the bmw e36 crankshaft sensor fails then the car won't work at all although no, it can work depending on the brain using the camshaft sensor information and going into emergency mode with the limit at the top. And then it will take a long time to look for the reason for the speed limit in the fuel system and the air supply system, when the car does not earn more than 3,5 or 4 thousand on the tachometer.

You can even splurge on a new injection pump or coil, or even climb inside the cylinder head, thinking about problems with the mechanics of the hydraulic compensator or cracked valves, but you need to start looking for a problem with the simplest: inspection, a complete check of all sensors, and the easiest way to do this is to do visual inspection of the wires and then go to computer diagnostics.

Sensors that control the operation of the BMW E36 engine

Additional sensors: running gear, comfort and so on

1. The brake pad wear sensor is installed inside the brake pad, it signals the limit of wear of the brake pads through a warning on the panel. It is clear that there are no such sensors on the rear drums.
2. The ABS sensor is located in the caliper of each wheel and monitors the correct operation of the ABS system. If at least one is not in order, the ABS will turn off.
3. The stove fan sensor is installed on the stove fan damper, in the place of air leakage.
4. The fuel level sensor is installed in the fuel tank in the block together with the fuel pump. Allows you to control the fuel level through the control panel.
5. The outside air temperature sensor is installed on the left wheel. It fits into a plastic tunnel attached behind the fender liner. There are far from all 36th.

Finally, one more important point for all these sensors: the ECU can switch the engine to different operating modes in case of problems with one or another sensor. This does not mean that the speed will stop rising above 3,5 thousand with a malfunction of the lambda probe or that the car will drive normally with a malfunction of the camshaft sensor. But in any case, the engine will no longer run according to the standard schedule, which may lead you to think about finding problems and fixing them.

1. The crankshaft sensor is located on the crankshaft pulley, almost under the cooling impeller, part number 22.
   
   There is no camshaft sensor on the M40. Correct me if I am wrong.
2. Idle air valve, also known as idle air control, part number 8 (see link below). It is located under the intake manifold.
   
   Mass air flow sensor, it is also a flow meter part No. 1. Located right after the air filter
3. Throttle position sensor, also known as shock absorber slag angular displacement sensor, part # 2 Located immediately after the rubber corrugation coming out of the flow meter.

And if the speed jumps, then first check for air leaks, check all air (vacuum) hoses for cracks, tears, etc., and then everything else.
