Where Is the Oil Pressure Sensor Located?

According to Repair Pal, the oil pressure sensor is normally found between the oil filter and the oil pan on the right side of an engine, close to the bottom. The placement of the oil pressure sensor, commonly referred to as the oil pressure switch or sender, varies depending on the make of a vehicle.

According to Autos.com, the oil pressure sensor measures the pressure at which the oil pump is dispensing engine oil. Between 20 and 40 pounds per square inch are the operating pressures of an oil pump in excellent condition.

If the pressure falls below this range, severe and long-lasting engine damage results. Electrical and mechanical oil pressure gauges are incorporated into the dashboards of certain vehicles, while signal lights are on in others. The driver is informed of problems through the oil pressure warning system of the car.

According to AutoZone, a damaged oil pressure sensor is frequently the root of a low oil pressure indication. If the oil pressure sensor detects low oil pressure even when the main gallery’s oil pressure is not low, the sensor is probably broken and needs to be replaced. The sensor can be examined by a mechanic for damaged or loose connections. A mechanic can search for indications of an oil leak if the oil level is low.
