Here is a more detailed list of the most common causes of an oil pressure light on your dashboard:
- Low Engine Oil Level.
- Faulty Oil Pressure Sensor.
- Faulty Oil Pressure Sensor Wirings.
- Faulty Oil Pump.
- Clogged Oil Pickup Tube.
- Clogged Oil filter.
- Faulty Instrument Cluster.
- Internal Oil Leak.
How long should oil pressure light stay on?
It should have 10w40 for an Auto. 5 seconds is a long time for the light to go out, but it could be the switch at fault. Change the switch first and if that makes no difference consider taking the engine out, checking/changing the bearings, fitting a new high-capacity oil pump and inspecting the crankshaft journals.
What are the signs of a bad oil pressure sensor?
Symptoms of a bad or failing oil pressure sensor
- The Oil Pressure Light is on. The oil pressure gauge inside your car will give you a good indication as to the condition of the engine’s oil levels.
- The Oil Pressure Light blinks constantly.
- Oil pressure gauge is at zero.
What does low oil pressure sound like?
When you have low oil volume or low oil pressure, you’ll commonly hear a “clattering noise” coming from the engine’s valves. This can come not only from not enough oil, but from the oil getting too old and starting to break down or foam.
What does a low oil pressure light mean?
Most modern vehicles, though, have done away with the oil pressure gauge, replacing it with a simple low oil pressure warning light, which illuminates when oil pressure drops below 5 to 7 psi. Generally-speaking, if your vehicle is equipped with an oil pressure gauge, it should never dip into the red zone at the bottom of the gauge.
How long does it take for an oil light to come on?

When to do an oil change for low oil pressure?
If you’re experiencing low oil pressure problems after an oil change or seasonal change, an oil change with the correct oil viscosity might remedy the situation. Some vehicles may specify different Summer and Winter oil blends. Be sure to complete any oil change services with the proper oil before the season changes.
