机油压力指示灯闪亮时,表明不是机油压力低,就是机油压力指示灯系统本身发生故障。因此,发生此故障时,首先应当检查润滑系统,是否机油压力过低,当排除润滑系统故障,使机油压力达到正常值时,机油压力指示灯仍然闪亮,表明机油压力指示系统本身发生故障。本文以桑塔纳轿车为例,对其机油压力指示灯系统本身发生故障时如何进行检查和排除作一介绍。 一、机油压力指示灯电路 图1为上海桑塔纳轿车电路图中的机油压力指示灯部分电路。位于图中的左侧,电路始端接于“15”线,这条线是
When the oil pressure indicator is flashing, it indicates that the oil pressure is not low, that is, the oil pressure indicator system itself has failed. Therefore, when this occurs, first check the lubrication system if the oil pressure is too low and the oil pressure indicator will flash to indicate that the oil pressure has failed to indicate the system itself when troubleshooting the lubrication system to bring the oil pressure to a normal level. In this paper, Santana sedan as an example, its oil pressure indicator light system failure itself how to check and eliminate an introduction. First, the oil pressure indicator circuit Figure 1 Shanghai Santana car circuit diagram of the oil pressure light part of the circuit. Located on the left side of the figure, the circuit begins with the “15” line, which is the line
