How can I test my oil pump?
How to Test an Oil Pump
- Check if the low oil pressure light is on or the oil pressure gauge reading is lower than usual.

What does the oil pressure low stop engine message mean?
The Oil Pressure Low – Stop Engine message appears when the oil pressure switch, which is located on the engine, has detected low oil pressure.
When does the low oil pressure warning light come on?
Assuming no other issues you should be good to go. If the oil pump were starting to go, one symptom would be oil pressure warnings when the engine is fully warmed (oil thins out) and engine speeds are low (like idling below 700 RPM). Oil pressure normally would be lowest at these speeds.
What should I do if my oil pressure is low?
Loss of engine oil pressure is a serious yet common matter with diesel engines. It should be noted that ignoring a low oil pressure warning could result in serious damage to your engine. The best way to keep your engine running is to regularly change the oil and keep the internal parts properly lubricated.
Can a high engine speed cause low oil pressure?
High engine speeds can cause faster than normal wear on crankshaft bearings, especially if combined with low-quality engine oils and longer than specified intervals in between oil changes.
The Oil Pressure Low – Stop Engine message appears when the oil pressure switch, which is located on the engine, has detected low oil pressure.
What to do when your oil pressure is low?
A faulty oil pressure switch/circuit or a bad oil pressure gauge could also be to blame. When this warning appears, the first thing to do is pull off to the side of the road to a safe location and shut the engine off. Next, open the hood and check the oil level on the dip stick. If the level is low, top it off.
What does the oil pressure warning light mean?
Last week I had a car come in with the complaint of oil pressure gauge goes to 0 and warning light comes on at idle. Instead of just replacing the switch for $50 labor, I removed the switch, installed a gauge, ran the engine and verified good oil pressure, and then installed a new switch for $100 labor.
