Engine Oil Pressure Switch
Mitsubishi FUSO®

The Engine Oil Pressure Switch (part number QC000476) is a small but critical component of a truck's engine. It is responsible for monitoring the oil pressure in the engine and sending signals to the vehicle's computer system if the pressure drops below a certain level. This helps to prevent damage to the engine by alerting the driver to any potential issues before they become serious. The switch works by using a spring-loaded piston that responds to changes in oil pressure, opening or closing an electrical circuit as needed. It is typically located near the oil filter or on the engine block itself, and can be easily replaced if it fails. Overall, this simple but important part plays a crucial role in keeping a truck's engine running smoothly and preventing costly damage over time.
