How to deal with error code?

What should you do if there is an error in the car's dashboard? The video describes what I want to do. Recently, I have experienced that the engine almost coughed like there was a misfire and several errors was shown in the dashboard. It was closed to get the car home despite the fact that the engine in a shorter time could not take the gas. The next day I checked the oil level and it was okay. I started the engine and it ran ok and only one fault remained. Then I used my BlueDriver OBD II scanner and cleared an error. It might have been bad fuel or an intermittent fault somewhere in the cars system.
There are many different censors in the car. And if one of them falls outside the normal range, a yellow warning light comes on. My experience is that error codes can occur if the engine briefly runs poorly or there is another short-term error somewhere in the car's system. My advice would therefore be to try to erase the error with a good OBD II scanner (avoid the very cheap scanners which are not really worth anything). And see if the error comes again. My experience is that the error often does not come back. When the lamp lights up yellow, it means that there is or has been an error. But that it does not damage the car to use it until the fault has been found and fixed. If a red light starts to light up, the car must be switched off immediately.
But now the car shows no errors and runs okay. If the same error occurs again, I will of course investigate what the error is and have the car repaired. And I will search for the error on youtube and the internet. But for now the problem is solved. A good OBD II scanner has paid for itself after being used a few times. I have experienced giving 100 dollars for an OBD II scan.

Difficulty: 2/5

Tools: Good OBD II scanner like BlueDriver (good for DIY people). It is easy to use with Android phone.
