From the Instruments and Controls chapter of the Nissan Altima owner’s manual:
While the engine is operating, if this warning light illuminates continuously or flashes, it can be a sign of a potential emission control issue. The fuel filler cap may be loose or missing, or the car may run out of fuel, which will also cause the malfunction indicator light to stay on continuously. Verify that the vehicle has at least 3 gallons (11.4 liters) of fuel in the tank and that the fuel-filler cap is installed and snugly closed.
If no other possible emission control system issue occurs, the light ought to go out after a few drives.
The vehicle is not prepared for an emission control system inspection or maintenance test if this indicator light illuminates steadily for 20 seconds and then blinks for 10 seconds without the engine running. See “Readiness
for the “Technical and Consumer Information” section for the inspection/maintenance (I/M) test “part of this guide.
One of two things will cause the Malfunction Indicator Light to illuminate:

The meaning of the malfunction warning
The Malfunction Indicator lamp (MIL), often known as the Check Engine Light, is a very important warning system, regardless of how you refer to it. It is intended to activate when your emissions system experiences a problem. Simple mistakes like leaving the gas cap off could cause the problem, or it could be something more significant like a broken oxygen sensor, catalytic converter, or another component. When you start the automobile, the Malfunction Indicator lamp should turn on, and it should quickly turn off once you perform a self-test. If it stays on or activates while you’re driving, the computer has to have a code examined.

Why does my automobile display a malfunction warning?
Flashes from time to time are an indication of momentary engine issues. In this situation, it is wise to be aware of potential concerns that may arise in the future and subsequently develop into more serious ones.
The indicator light staying on continuously is the most typical scenario. It suggests a more serious issue that needs to be addressed; the sooner the better. However, occasionally minor problems might still have an impact on a vehicle’s emissions, for instance.

Note: When you start the engine, the light will shine for a brief period of time. But if the engine is running, it ought to shut off.
What could lead to an engine problem?
- a lack of lubrication
- defective oil pump.
