What is the function of the oil pressure sensor?

• A. 24 volt, used to start diesel engine
• B. Provides operator with indication of the amount of the engine oil pressure
• C. Removes solid contaminants from air entering the turbo-charger
• D. Used to deliver fuel from the tank to the ejectors

Answer: (B)

An oil pressure sensor is part of the lubrication system that measures the oil pressure in the engine and sends a signal to the instrument cluster or engine control. Its job is to provide the operator with a reading of how much oil pressure the engine has, so you can monitor lubrication health and get warnings if pressure drops. It does not supply starting power, it doesn’t filter air for the turbocharger, and it doesn’t deliver fuel to the injectors—those are different systems.
