1.Direct installation is OK, as long as the timing is right, the installation of the sensor does not need to be marked. The crankshaft position sensor of this car is not very easy to install.
2.There are three types of crankshaft position sensors: electromagnetic pulse crankshaft position sensor, Hall effect crankshaft position sensor (Santana 2000 sedan and Beijing Cherokee), and photoelectric effect crankshaft position sensor.
The vehicle sensor is the input device of the automobile computer system, which converts the information of various working conditions in the operation of the car, such as vehicle speed, temperature of various media, engine operating conditions, etc., into telecommunication signals and transmits them to the computer, so that the engine is in the best working condition. There are many sensors in automobiles, and when judging the failure of the sensor, it is necessary to consider not only the sensor itself, but also the entire circuit where the fault occurred. Therefore, when looking for faults, in addition to the sensor, it is also necessary to check the wiring harness, the connector, and the relevant circuitry between the sensor and the electronic control unit.
The intake pressure sensor can measure the absolute pressure in the intake manifold according to the load state of the engine, and convert it into an electrical signal and a speed signal and send it to the computer together as the basis for determining the basic fuel injection volume of the injector.

Automotive oxygen sensors are mounted on the engine exhaust pipe.
The automotive oxygen sensor is the key feedback sensor in the EFI engine control system, and is the key component to control automobile exhaust emissions, reduce environmental pollution of automobiles, and improve the fuel combustion quality of automobile engines.
1. The function of the camshaft position sensor is to collect the camshaft moving angle signal and input it into the electronic control unit (ECU) in order to determine the ignition time and fuel injection time, so there are both intake and exhaust;
2. So as to carry out sequential fuel injection control, ignition time control and deflagration control. In addition, the camshaft position signal is used to identify the first moment of ignition when the engine is started. Because the camshaft position sensor is able to identify which cylinder piston is about to reach the top dead center, it is called a cylinder recognition sensor.
The development trend of automotive oxygen sensors:
For the automotive oxygen sensor, its working environment is very harsh, working at a high temperature of 500 800, usually to withstand the influence of about 30 climate temperature. Therefore, expanding its working temperature range, especially the working stability and durability in the commercial temperature zone, has become a direction for material improvement.

The crankshaft position sensor is installed on the transmission clutch housing, located behind the left side of the engine block, the crankshaft position sensor is fastened with two bolts, and the underside of the crankshaft position sensor is padded with adhesive tape or cardboard pads to adjust the depth of the sensor, once the engine is started (after the crankshaft position sensor is installed), the excess part of the paper pad should be cut off.
The new spare sensor will carry this pad, and if the original crankshaft position sensor is reinstalled, or if the transmission and clutch housings are replaced, a new gasket must be installed.

How the crankshaft position sensor works:
There are three main types: magnetoelectric induction, Hall effect, and photoelectric. The three types work on the following principles:
1. Magnetoelectric induction:
The magnetoelectric inductive speed sensor and the crankshaft position sensor are installed in the distributor in two layers. The sensor consists of a permanent magnet induction detection coil and a rotor (timing rotor and speed rotor) that rotates with the distributor shaft. Timing rotor has.
One, two, or four teeth, etc., the speed rotor is 24 teeth. The permanent magnet induction detection coil is fixed on the distributor body. If the speed sensor signal and the crankshaft position sensor signal are known, as well as the working sequence of each cylinder, the crankshaft position of each cylinder can be known.
Rotor signal panels for magnetoelectric inductive speed sensors and crankshaft position sensors can also be mounted on crankshafts or camshafts.
2. Hall effect:
Hall-effect speed sensors and crankshaft position sensors are signal generators that utilize the Hall effect. The Hall signal generator is installed in the distributor, coaxial with the distributor head, and is fixed on the distributor panel by the encapsulated Hall chip and a permanent magnet. The number of notches on the trigger impeller is the same as the number of engine cylinders.
When the blade on the trigger impeller enters between the permanent magnet and the Hall element, the magnetic field of the Hall trigger is bypassed by the blade, and the Hall voltage is not generated, and the sensor has no output signal; When the notched part on the trigger impeller enters between the permanent magnet and the Hall element, the magnetic field lines enter the Hall element, the Hall voltage rises, and the sensor outputs a voltage signal.
3. Photoelectric type:
Photoelectric crankshaft position sensors are generally installed in distributors and consist of a signal generator and a signal disc with light holes. The signal panel rotates together with the distributor shaft photoelectric type, and there are 360 lithography gaps in the outer ring of the signal panel, which produces a signal with a crankshaft rotation angle of 1 °; Slightly inward, there are 6 orifices evenly spaced 60 ° apart, generating a signal of a 120° angle of rotation of the crankshaft, one of which is wider to generate a signal relative to the top dead center of the 1st cylinder. The signal generator is mounted on a distributor housing and consists of two light-emitting diodes, two photodiodes and a circuit.
The light-emitting diode is facing the photodiode. The signal disk is located between the light-emitting diode and the photodiode, and because there is a light hole on the signal disk, the phenomenon of alternating light transmission and shading occurs. When the beam of the light-emitting diode hits the photodiode, the photodiode generates a voltage; When the LED beam is blocked, the photodiode voltage is 0.
These voltage signals are amplified by the partial shaping of the circuit and are transmitted to the electronic control unit (ECU) at 1° and 120° crankshaft rotation angles, which calculates the engine speed and crankshaft position based on these signals.
Crankshaft position sensors are usually installed in distributors and are one of the most important sensors in control systems. Its functions are: detecting engine speed, so it is also called speed sensor; Detecting the position of the piston top dead center, so it is also called an top dead center sensor, which includes the detection of the top dead center signal of each cylinder used to control the ignition, and the top dead center signal of the first cylinder used to control the sequential fuel injection.

The function of the crankshaft position sensor is to determine the position of the crankshaft, i.e. the angle of rotation of the crankshaft. It usually works in conjunction with a camshaft position sensor – to determine the basic ignition moment. We all know that the engine starts igniting at the end of the compression stroke, so how does the engine computer know which cylinder is due to ignite?
It is calculated by the signal of the crankshaft position sensor and the camshaft position sensor, through the crankshaft position sensor, you can know which cylinder piston is at the top dead center, and through the camshaft position sensor, you can know which cylinder piston is in the compression stroke. In this way, the engine computer knows which cylinder to fire when to fire.

Different sensors are installed in different locations. The location of the Volkswagen Santana sensor is as follows:
1.Oxygen sensor: The oxygen sensor is installed on the exhaust pipe to monitor the gas celestry after combustion, and judge whether the engine combustion is sufficient, and the mixture is too thin or too thick;
2.Wheel speed sensor: The wheel speed sensor is usually located inside the front brake disc and mainly collects the speed of the car to determine if the car has signs of skidding.
It is suspected that there is a sensor that collects the wheel speed of the car to complete this work, which is generally installed on the hub of each wheel, and once the sensor is damaged, the ABS will fail;
3.Water temperature sensor: The water temperature sensor is installed next to the thermostat bending group, which converts the temperature of the cooling water into an electrical signal, increases the amount of fuel injection or ignition advance angle at low temperature, prevents ** at high temperature, and delays the ignition advance angle;
4.Intake pressure sensor: Generally installed at the throttle, the intake pressure sensor, as the name suggests, senses a series of resistance and pressure changes when the engine speed load is different, and converts it into a voltage signal for ECU to correct the amount of fuel injected and the ignition timing angle.
If something goes wrong, it will cause problems such as ignition difficulties, unstable idling, and weak acceleration.
Different sensors have different locations and mounting methods.
