How to disassemble and assemble Volkswagen Santana sensor

Bian Xiao sorted out the related contents of "How to disassemble and assemble the Volkswagen Santana sensor" that people often pay attention to, as shown in the following figure. Different sensors are installed in different locations.

The disassembly of Volkswagen Santana sensor can be carried out according to the relevant maintenance manual. There are different sensors in the vehicle, which have different functions and are installed in different positions. If the sensor is damaged, it needs to be replaced in time, otherwise it will affect the driving safety of the vehicle. The types and functions of sensors are as follows:

1. Intake pressure sensor: it reflects the change of absolute pressure in the intake manifold and provides a reference signal for ecu (Engine Electronic Control Unit) to calculate the fuel injection duration;

2. Throttle position sensor: measures the throttle opening and provides it to ecu as a reference signal for fuel cut-off, air-fuel ratio control and ignition advance angle correction;

3. Air temperature sensor: detects the intake air temperature and provides it to ecu to calculate the air density; Coolant temperature sensor: detects the temperature of coolant and provides engine temperature information to ecu;

4. Crankshaft position sensor: detects the rotating speed of crankshaft and engine, and provides it to ecu as reference signal to determine ignition timing and working sequence;

5. Oxygen sensor: detect the oxygen concentration in the exhaust gas and provide it to ecu as a reference signal to control the air-fuel ratio near the optimal value (theoretical value); Knock sensor: installed on the cylinder block to detect the knock of the engine and provide it to ecu to adjust the ignition advance angle according to the signal.
