Industry News---Conventional Failure Behavior of Automotive Sensors!

Automotive sensors are very important components, and if they are damaged, they will not work properly. This time, I have sorted out some fault manifestations of conventional sensors, 

and you can use these performances to determine which sensor has a problem.

Air flow sensors

At present, there are two main types of hot wire air flow sensors and hot film air flow sensors, which are generally installed between the air filter and the throttle valve.

Function: Measure the air intake of the engine and input the signal into the ECU as the main control signal for fuel injection and ignition control.

Failure mode: When the air flow meter fails, the ECU cannot detect the true amount of air intake, resulting in an imbalance in the mixture, resulting in unstable engine idling, weak driving 

and black smoke, and sometimes shifting gears and stalling.
