How long do oil pressure sending units last?
Like all of the other sensors and switches on a car, the oil pressure sensor is built to last just as long as the car does. Generally, this will not be the case due to the wear and harsh conditions that the sensor is exposed to, it will usually become damaged and will have to be replaced.
How does an oil pressure sending unit work?
An oil pressure sending unit controls either the oil pressure light or gauge in your dashboard. When it detects oil pressure in the vehicle, a switch trips and either the light shuts off, or the gauge becomes active.
Is there a way to test an oil sending unit?
The indicator tells the driver of any problems with the oil pressure. Low oil pressure can lead to engine damage, but you can test the sending unit if you believe it isn’t accurate. You can buy or rent an oil pressure testing gauge at most auto parts stores.
