Average rating from 104 customers who received a Oil Pressure Light is on Inspection. The oil pressure in a vehicle engine plays an important role in making sure that lubricants reach the areas they need to, including the camshaft, main, and balance shaft bearings.

Why does my oil pump have no pressure?

Another possibility if you haven’t actually checked the oil pressure with a mechanical gauge is that the sensor is gummed up and sticks for a bit on the first cold start before it begins measuring properly. Thought all oil pumps had relief valve for cold starts? Cold oil is thick, high viscosity.

When does the oil pressure come back up?

After the engine has been running for about a minute or so the oil pressure finally comes up but not to normal. Once the engine has warmed up the oil pressure returns to what could be considered “normal”.

Is there a check valve in the oil pump?

There is no check valve in the oil pressure system. But, for many cars, there is a back flow valve in the oil filter to keep the oil from running out as it sits overnight. It could take several seconds for an oil pump to refill a side-mounted oil filter that is empty. I notice it all the time during oil changes.

What to do if your car has no oil pressure?

Once the engine has warmed up the oil pressure returns to what could be considered “normal”. After the cold start, no oil pressure problem, the engine and the oil pressure is fine for the rest of the day. Let it even set overnight though and I have a repeat no oil pressure with start up.

When checking the oil pressure gauge, keep in mind that the pressure reads higher in cold weather due to the higher thickness (also known as viscosity) of the oil. The inner workings of an oil pressure gauge depends in large part on the type: electric or mechanical.
