What causes the electrical failure of the Magotan oil pressure regulating valve?
2 Answers
Magotan oil pressure regulating valve electrical failure may be caused by an electrical converter malfunction. Below are the detailed explanations of the causes: Introduction to electrical equipment failure in electrical faults: 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. In actual automotive use and maintenance, electrical equipment failures are often caused by circuit faults. Introduction to electrical circuit failure in electrical faults: Electrical circuit failures include open circuits, short circuits, loose connections, poor contact or insulation, excessive resistance, etc. This type of fault can sometimes create illusions, making fault diagnosis difficult. For example, poor contact between a ground wire and the vehicle body may cause uncontrolled switching of electrical equipment and operational chaos. 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 leading to abnormal operation of one or more electrical devices through other circuits seeking grounding paths.
The electrical fault in the Magotan's oil pressure regulating valve is usually caused by electrical connection issues. I've encountered similar situations, simply put, it's due to poor wire contact leading to signal interruption, which prevents normal control of oil pressure. Possible causes include loose connector plugs that disconnect when the vehicle bumps; aging, corroded, or damaged wires that prevent current from passing; internal sensor failure in the regulating valve, resulting in abnormal output voltage; or the body control unit falsely reporting signals, which requires a diagnostic tool to read the error code for confirmation. When this occurs, the dashboard warning light will illuminate, and even the engine may run unevenly with insufficient power. It is recommended to immediately check the wire connections and clean any oxidation layers. If the fault persists, it's best to take the vehicle to a service station to replace the valve to prevent low oil pressure from damaging the engine's core components. The repair cost is not high, but delaying it could lead to major repairs.
