Classification of sensors in the car and the impact of the broken sensor
Mainly have the following sensors：
There are vehicle speed sensor, temperature sensor, shaft speed sensor, pressure sensor, etc., angle sensor, torque sensor, hydraulic sensor; vehicle speed sensor, acceleration sensor, body height sensor, roll angle sensor, angle sensor, etc.
Classification of sensor operating principles：
Physical sensors use physical effects such as piezoelectric effects, magnetostriction, ionization, polarization, thermoelectric, optoelectronic, magnetoelectric and other effects. Minor changes in the measured semaphore will be converted into electrical signals.
Chemical sensors include those that cause a causal relationship between chemical adsorption, electrochemical reactions, etc., and small changes in the measured signal volume are also converted into electrical signals. Some sensors can neither be classified into physical classes nor classified into chemical classes.
The impact of the broken sensor
Water temperature sensor is bad - water temperature meter is not normal
Crankshaft position sensor, camshaft position sensor is bad - the car can not start
Intake pressure sensor, intake air temperature sensor ---- injection volume is not normal, may lead to oil truck
Knock sensor - is the engine combustion produces knock, damage the engine
Vehicle speed sensor, speed sensor----tachometer or speedometer display fault.
