2005 Sportsman 800

I’ve owned this atv for about two weeks. I’ve rode it for less than 3 miles. The wrench and the check engine always come and blink at start up, but disappears once the engine is running. I figured out how to check codes. I’m receiving a 42 code. The question I have is once I fix and clear the code will the wrench and check engine always display at start up or will I only see that when there’s an issue?
