What is the reason for the electrical failure of the oil pressure regulator valve?

Here are the reasons for the failure of the electrical converter: 1. Inaccurate zero point and range; 2. Due to inaccurate installation and debugging or on-site vibration, temperature changes, etc., the zero point and range of the converter's output signal are inaccurate, resulting in the regulating valve not being able to fully open or close, with large leaks and limited flow. Below is additional information about the electrical converter: 1. The electrical converter is a direct-acting (non-feedback) instrument that can obtain high-power pneumatic output signals; 2. The electrical converter uses open-loop control and small mass magnets to achieve precise pneumatic control at a relatively economical cost, unaffected by position and resistant to RFI/EMI interference.
I had this issue with my old car before. The electrical failure of the oil pressure regulating valve mainly refers to problems with the wiring or circuits, such as coil short circuits or poor contact at the terminals. Back then, the car kept triggering the oil pressure warning light. I suspected it was the electronic part of the valve acting up—maybe unstable voltage damaged the coil, or the wiring was corroded and short-circuited due to aging. This component controls oil pressure, and if the electronic control fails, the oil pressure fluctuates unpredictably, potentially causing engine overheating or wear damage. At best, it increases fuel consumption; at worst, it could lead to a major engine overhaul. First, I checked the fuse to see if it was blown, then used a multimeter to test the coil's conductivity. Turns out, the coil's resistance was off, so I replaced the entire valve assembly. When driving, it's best to keep an eye on the dashboard lights—if they flash, pull over and check immediately. Don’t delay—it saves money and keeps you safe.
