The answer to the question, "Does the check engine lamp have to be on to receive codes?" It all depends on the problem. To pull codes, the check engine lamp is sufficient to identify non-emissions problems, such low oil pressure. However, you won't need the check engine lamp to pull codes if the engine isn't firing.
For non-emissions related issues, you don't need a lit check motor light to pull codes
OBD codes are not able to diagnose all problems. These diagnostic codes are a general indicator of the problem that's causing the Check Engine Light to come on. These codes contain a variety of numbers and letters that indicate problems with the vehicle’s emissions system. Some codes have a single digit, such as "0300", while others contain pairs of numbers ranging from 00 up to 99.
The good news? You can check these codes easily yourself. Many vehicle models include an onboard computer that stores fault codes. A simple Bluetooth-powered device or a handy app can help you read and interpret these codes. This information will save you time, money and effort. If you're unsure of what these codes mean, consult your local mechanic or auto parts store.
Low oil pressure
Your vehicle's low oil pressure warning light is illuminated when it is moving. If your oil pressure is less than 5 or 10 PSI at idle, you may hear a knocking sound. This means that there is an issue with your oil pressure sensor. You could end up with expensive engine damage if you continue to drive your vehicle at low oil pressure. When your vehicle's engine oil pressure reaches dangerously low levels, you should stop driving it and take it to the mechanic.
First, check the oil level in your vehicle to determine what's causing this 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 verify that your engine is at the right oil pressure, you can access your mechanical oil pressure gauge. You also need to check the wiring and connections.
Engine misfiring
A misfiring engine code indicates that your car is experiencing issues with the combustion process. It could be that your car is jerking when you drive it. It could be caused, for example, by malfunctions in the oxygen sensor and mass airflow sensors. Another cause could be a malfunctioning fuel delivery system. This is the good news: there's a way to quickly diagnose it. The diagnostic trouble code reader will help you pinpoint the exact problem.
Incorrect fuel/air mixtures are often the cause of misfiring problems. A malfunctioning oxygen sensor or inefficient single injector can cause misfiring. An engine compartment inspection is required to determine the exact cause. Common symptoms include minor backfires and inconsistent engine revs.
