VEMO Oil Pressure Switch V15-99-1995

VEMO Oil Pressure Switch V15-99-1995

The VEMO Oil Pressure Switch V15-99-1995 is a precision‑engineered component designed to monitor and regulate engine oil pressure in a wide range of automotive powertrains. This switch plays a critical role in safeguarding the engine by ensuring that oil pressure remains within safe operating limits, thereby preventing potential damage caused by low or high pressure conditions.

Core Functionality

The switch operates as an oil pressure sensor and relay combined. It continuously measures the pressure of circulating engine oil and triggers a signal to the vehicle’s electronic control unit (ECU) when pressure deviates from predefined thresholds. This real‑time feedback allows the ECU to adjust fuel injection, ignition timing, or activate warning indicators, ensuring optimal performance and protection.
