Oil pressure switches are notorious for leaking as they age. When that happens, they send erroneous data to the computer, and you end up with a glowing “oil” light. First, perform a visual check of the switch. If you see fresh oil on it (and it’s not leaking from another component above it), it’s toast.
And here’s the answer you’re looking for. A collection of related questions and answers you may need from time to time.

Do oil sending unit leak? – Frequently asked questions
-
How do I know if my oil sending unit is leaking?
If your vehicle has an oil leak, the engine oil pressure inside of your vehicle will decrease. The oil pressure sensor will detect this reduction of pressure, which it will use to trigger the oil pressure light. Nonetheless, a bad oil pressure sensor may result in this dashboard light being constantly illuminated -
Can a oil pressure switch leak oil?
Oil pressure switches can develop external leaks (that is, they can leak oil onto the engine) and/or the switch can fail internally such that the switch either fails to warn of low oil pressure or the switch goes off prematurely and illuminates the oil pressure warning light when in fact nothing is wrong -
How do I stop my oil pressure sensor from leaking?
When your oil pressure sensor is about to fail, the Low Oil light will blink on and off. This can be quite frightening to a car owner since low oil could cause significant damage to an engine. Continually checking your engine oil is not only time consuming but also stressful -
What happens when an oil sending unit fails?
The average oil pressure sensor replacement cost is between $50 and $250, depending on the car model and labor costs. An oil pressure sensor costs $30 to $100, and the labor costs $20 to $150. -
How much does it cost to replace an oil sending unit?
