What does it mean when the pressure regulating valve 2 is open-circuited and shorted to ground?

MAGOTAN oil pressure regulating valve electrical failure may be due to an electrical converter malfunction. The following are specific explanations of the causes: Introduction to electrical equipment failure: Electrical equipment failure refers to the loss of the original function of the electrical equipment itself, including mechanical damage, burnout of the electrical equipment, breakdown, aging, or performance degradation of electronic components, etc. In actual automotive use and maintenance, electrical equipment failures are often caused by circuit faults. Introduction to electrical circuit faults: Electrical circuit faults include open circuits, short circuits, loose wiring, poor contact or poor insulation, excessive resistance, etc. These types of faults can sometimes create illusions, making fault diagnosis difficult. For example, if a ground wire has poor contact with the vehicle body, it may cause the electrical equipment switch to malfunction and the electrical equipment to operate chaotically. This is because some ground wires are shared by multiple electrical devices. Once the ground wire has poor contact, it connects the working circuits of multiple electrical devices, potentially finding an alternative grounding path through other circuits, resulting in abnormal operation of one or more electrical devices.
