Hello! I have an Isuzu NPR 2006, and I want to turn off my check engine light, but have no idea how. I checked my check engine and it said that my cool system wasn't working properly but when I checked my cooling system it was fine, it good. And now I'm a bit confused. Thank You to anyone who can answer my question!

Hello,

It sounds like the engine is over heating causing the check engine light to come on. The most popular reason for this problem is a coolant leak. I would do a pressure test to see what you can find. Here are a few guides that can help you with the problem and get it fixed.
