The oil pressure sensor in a 2012 Chevy Equinox can be found at the lower a piece of the motor close to the oil channel lodging itself. There are three wires that go to a sensor here and that is why You will look. The oil pressure sensor is intended to do precisely exact thing it seems like it would do</br> measure the oil strain in Your motor. In the event that this is bombing You will see the measure on Your scramble not showing the right oil pressure. This can likewise prompt the ECU not realizing how much oil is traveling through the motor and that can prompt the oil siphon not running as expected too. I suggest supplanting the sensor on the off chance that it begins to come up short.
