An air flow meter sensor fault simulation detection joint and its use method

Abstract

The invention discloses an air flowmeter sensor fault simulation detection joint and its use method. There is a horizontally penetrating installation channel between the middle part of the housing and the interface at the left end of the housing, and the top surface of the middle part of the housing is vertically provided with a channel communicating with the installation channel. Hole, the first pin with a bent portion located in the interface at the left end of the housing; the second pin with a bent portion located in the interface at the right end of the housing, which can perform fault simulation and failure on the connecting plug Detection; an on-off switch for controlling the on-off relationship between the first pin and the second pin; by moving the on-off switch up and down to switch the state between the first pin and the second pin, the fault can be quickly performed Simulation and testing, the training has a high degree of fidelity and has a good training effect.

Description

technical field [0001] The invention relates to the related technical field of sensor fault simulation detection, in particular to an air flow meter sensor fault simulation detection joint and a use method thereof. Background technique [0002] Automobile fault diagnosis training is a very important course in vocational colleges. In automobile fault diagnosis training, air flow meters are generally used to measure the flow of gas, which is conducive to the detection of flow as an important control parameter (instructions attached figure 1 As shown), the currently commonly used fault diagnosis bench method uses the circuit diagram plus panel detection port method on the bench panel. Since the detection process does not touch the actual vehicle sensor, it is impossible to obtain the real detection environment of the vehicle fault diagnosis. The training effect is not ideal, and the power plug needs to be unplugged during the detection process to cause the circuit to be disconn...

[0002] Automobile fault diagnosis training is a very important course in vocational colleges. In automobile fault diagnosis training, air flow meters are generally used to measure the flow of gas, which is conducive to the detection of flow as an important control parameter (instructions attached figure 1 As shown), the currently commonly used fault diagnosis bench method uses the circuit diagram plus panel detection port method on the bench panel. Since the detection process does not touch the actual vehicle sensor, it is impossible to obtain the real detection environment of the vehicle fault diagnosis. The training effect is not ideal, and the power plug needs to be unplugged during the detection process to cause the circuit to be disconnected

[0003] In the prior art, this kind of charged detection usually needs to be detected after breaking the wire. Therefore, we propose an air flow meter sensor fault simulation detection joint and its use method. The present invention does not need to break the wire for detection. A fault diagnosis detection joint is installed between the connection plugs, which has fault setting and detection functions to solve the above problems
