The answer to the question, "Does the check engine lamp have to be on to receive codes?" Depends on the issue. For non-emissions related issues, such as Low oil pressure, you don't need the check engine light to pull codes. You don't also need the check engine light to pull codes if your engine is not firing properly.
To pull codes for non-emissions problems, a lit check engine lamp is not required
OBD codes cannot diagnose every problem. These codes can be used to identify the cause of the Check Engine Light coming on. These codes consist of a number of letters and numbers that indicate an issue with the vehicle's emission system. Some codes can be single digits like "0300", and others can include a combination of numbers between 00 and 99.
The good news? You can check these codes easily yourself. The fault codes are stored on most vehicle models. These codes can be read and interpreted using a simple Bluetooth-powered device, or an app. Having this information in hand can save you a lot of time and money. You can ask your mechanic or local auto parts shop for clarification if you are unsure what these codes mean.
Low oil pressure
Your vehicle's low oil pressure warning light is illuminated when it is moving. If your oil pressure is lower than 5-10 PSI at idle, it may make a loud clicking sound. This indicates a problem with your oil pressure sensor. Driving your vehicle with low oil pressure could cause costly engine damage. If your vehicle's oil pressure drops to dangerous levels, it is best to stop driving it and bring 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. Also, it is possible to check the maintenance history for your vehicle to determine if there are any problems. To check the oil pressure in your engine, you can also access the mechanical oil pressure gauge. It is also important to check the wiring, connectors and other components.
Engine not starting
An engine code that is failing to fire means that your car has problems with the combustion process. Your car might jerk if it has a misfire. It could be caused, for example, by malfunctions in the oxygen sensor and mass airflow sensors. Another possible cause is a malfunction in the fuel delivery system. It is possible to diagnose this problem cheaply. The best way to determine the exact cause of the problem is to use a diagnostic troublecode reader.
Misfiring can often be caused by incorrect fuel/air mixture. A malfunctioning oxygen sensor or inefficient single injector can cause misfiring. A thorough inspection in the engine compartment is essential to identify the exact cause. Some common physical symptoms are minor backfires, inconsistent engine revs, and unusual sounds coming from the engine bay.
FAQ
What is the difference in a mechanic and an auto technician?

An automotive technician needs to be more technically skilled than a mechanic. They need to be able use tools such drills and wrenches, and read blueprints.
They must be able and competent to safely perform complicated procedures. They need to be familiar with various types of engines and electrical system.
They should also be able understand how different parts interact.
A mechanic typically earns less than an automotive technician. Both careers have many options.
Can I work as an auto mechanic without a degree? Can I study part time?
While a degree is not required, it does help. Most employers prefer candidates who have studied for a full degree rather than those who haven't. It shows that you've put the effort in and have done everything possible to succeed.
But, this doesn't mean you have to stop working while studying. Some universities let students complete their coursework in the summer and then continue their studies during the school year. Other universities permit students to take classes part-time during the school year.
What qualifications do I need to become a mechanic?
You will need to pass several exams in order to become a mechanic. These include:
-
A general knowledge exam
-
A practical examination
-
An apprenticeship test
These tests are meant to help you grasp the fundamentals of mechanical engineering and physics, before you begin your journey as a mechanic.
These tests will allow you to be a mechanic once you have passed them. But, you will still need an apprenticeship. This will involve trade training.
To be able to repair vehicles, you'll need classes or workshops. It will be necessary to work alongside experienced mechanics.
