Abstract
With the development of modern electronic technology,automotive electronics and the increasingly high,vehicle sensors automotive electronic control systems e an ponent parts,automotive electronics technology is also on one of the core technology,the use of sensor technology and the number of decision Hyundai Motor control system performance,some of the basic vehicle technical performance are directly or indirectly,with the engine sensors linked to the performance. The performance of the car to have a direct impact on the momentum of the economy, reliability,safety and emissions purification fort.
This paper mon control engine sensor fault of their impact on the operation of the first sensor on the development of domestic and international status and development trend,on mon electronic control engine sensor installation location, function and working principle,the main aerobic Sensors,knock sensors,air flow sensors, throttle position sensor,crankshaft position sensor,temperature sensor. This was followed by a detailed analysis of sensor failure of the electrical control engine operation in the impact of sensors to detect and diagnosis,the use of multimeter measured value of the corresponding voltage and resistance,the sensors to determine whether the good working condition. And to study specific examples of that sensor failures to the engine electronic control the operation of a serious impact.
