Oil pressure sensor is broken, the most obvious reflection is;
1, the oil alarm light will always be on, can not know the real-time situation of the oil, can not remind the owner in time.
2, if you continue to drive in the case of too high pressure or lack of oil, it will certainly have a great impact on the engine, and even may be scrapped directly.
3, if the short-circuit display is normal, it means that the sensor is normally open switch output.
4. There are only two states of switching quantity. If there is oil in the chassis, but the sensor still does not output, the sensor is damaged.
