The answer to "Does a check engine light have t be on in order to generate codes?" is no. depends on what the problem is. The check engine light is not required to pull codes for issues that aren't emission related, such as low oil pressure. If your engine is having problems, you don’t need to have the CEL lit in order to pull codes.
Non-emissions related problems do not require a lit check engine light to pull codes
OBD codes cannot diagnose every problem. These codes provide a general indication of the problem that is causing the Check Engine Lights to turn on. These codes consist of a number of letters and numbers that indicate an issue with the vehicle's emission system. Some codes are single digits, like "0300," while others are pairs of numbers from 00 to 99.
The good news? You can check these codes easily yourself. Most vehicles have an onboard computer which stores fault codes. You can read and interpret these codes using either a Bluetooth-powered phone or an app. This information is invaluable and can save you time and money. Consult your local mechanic or auto part store if you have any questions.
Low oil pressure
The low oil pressure check engine light illuminates while your vehicle is in motion. You may hear a clicking sound if your oil pressure is below 5 or 10 PSI while the vehicle is in motion. This means that there is an issue with your oil pressure sensor. If your vehicle's oil pressure is low, it can lead to expensive engine damage. When your vehicle's engine oil pressure reaches dangerously low levels, you should stop driving it and take it to the mechanic.
Check the oil level to find out what is causing the engine to display the error code. You should inspect the oil level if the oil doesn't look dirty. You can also check your vehicle's maintenance history to determine if there is a problem. To verify that your engine is at the right oil pressure, you can access your mechanical oil pressure gauge. You should also check the wiring and connectors.
Engine misfiring
An engine code that is failing to fire means that your car has problems with the combustion process. Your car may jerk when it misfires. It could be caused either by malfunctioning in the oxygen sensor (or the mass-airflow sensor). A malfunction in fuel delivery could also be a possible cause. There is an easy way to diagnose the problem. Using a diagnostic trouble code reader can help you determine the exact problem.
Misfiring is often caused by an incorrect mixture of fuel and air. It can be caused by a malfunctioning oxygen sensor, an ineffective single injector, or even a vacuum leak. It is important to inspect the engine compartment thoroughly in order to find the cause. A few common symptoms include small backfires, irregular engine revs, or unusual sounds coming out of the engine bay.
FAQ

What information do I need about car mechanics
For an auto mechanic job, you don’t have to be an expert in cars. The only thing you need is the ability to fix them. Most people begin by changing brake pads and tires, before moving on to more complicated repairs.
It is important to be able to read and understand diagrams as well as written instructions. Also, you will need to know how to tell if parts require replacing or repair.
You should not attempt to fix vehicles without proper training and guidance. This is especially true if you deal with expensive components such as engines or transmissions.
Although you won't have to know much about automobiles, you must be familiar with the basics of mechanical engineering as well as physics. This is how you understand the mechanisms behind engines and brakes.
Noting that all situations are possible, it is important to be prepared. For instance, you might find yourself in charge of a vehicle that has been in a serious accident. Experience with accidents and breakdowns is also a must.
It is important to be open to learning new skills quickly. Not only will you need to be capable of diagnosing problems, but you also need to be able perform simple maintenance tasks like tightening nuts.
What is the distinction between a mechanic or an automotive technician?
These two jobs are very similar but not identical. A mechanic repairs cars while an automotive technician does maintenance on them.
A mechanic must be skilled in manual dexterity and able to complete simple tasks quickly. They should be able to accurately diagnose problems and repair them efficiently.
An automotive technician must be more technically proficient than a mechanic. They need to be able use tools such drills and wrenches, and read blueprints.
They should also be capable of safely performing complex procedures. They must also be familiarized in different types and electrical systems.
They must also be able to understand how various parts interact with each other.
The result is that a mechanic often earns less than an auto technician. Both jobs offer many possibilities.
