In the event that the oil pressure switch has tripped halfway, it is best to park the car in a safe place and wait for the tow truck to arrive, as if you continue on your way, it may end up with a more complex malfunction.
Modern cars are equipped with a variety of sensors that help us detect a possible malfunction before it's too late. Some are tasked with overseeing more complex systems than others, but they are all certainly important.
The oil pressure gauge is one of the most important, and it's imperative that it's working properly to know when the pressure isn't adequate.
What is an oil pressure sensor?
An oil pressure sensor is a device used to measure the oil pressure in an engine.
The sensor is responsible for sending pressure information to the control unit (ECU). Its operation has an electromechanical principle, giving a signal to the instrument panel and thus indicating whether everything is going well or something is no longer working.
How does the oil pressure sensor work?
Its work is carried out due to atmospheric pressure, if the air flow creates some force, it is converted into voltage, etc., which leads to reading. In this device, you can also find a cam and a coil of resistance wire.
The severity of the problem can also be indicated by the color of the symbol on the instrument panel, if it is activated. If the control lamp is yellow, the oil level is below the minimum, and if red, it means that it is not enough.
How is the oil pressure sensor activated?
This oil pressure switch activates when the required pressure is not available, activating the oil pressure check icon on the dashboard. It is important to pay attention, and if this is activated, you should take it to the workshop as soon as possible so that the oil works properly, if this is not paid attention, the problem can become very serious for your car.
It is also important to note that this sensor can fail and result in poor readings and lights, in which case it will need to be replaced.
How to check the oil pressure sensor?
The test is usually done with an electrical test tool called a multimeter. Like all tests, it must be performed by someone who is appropriately qualified and competent to administer the test.
