Known in most quarters as the malfunction indicator light (MIL), it is meant to give you the warning that the engine computer, through its electronic control unit has detected a problem within the engine.
Other cars are fitted with another light called the service required light calling for oil replacement on the engine.
What may be different is the onboard diagnostic scanner in use as the Honda car may have its manufacture fitted OBD scanner, or it may be one of the custom tools which work across most of the cars.
The ominous fear of this could be making you to panic is common in most scenarios when drivers start sweating profusely on sighting this. You don’t need to worry, take heart, you only need to look at the error codes to understand them and get into the act of correcting the car engine fault.
You may not be in the category of those who panic because you have some knowledge on the check engine light illumination light. However, you need some tips to help guide you as you how to go about it so that this manual will help you a lot. Read on;
What it means when check engine light is on or flashing
So your Honda check engine light is on, and the butterflies are all over your bowels as to what it means. It could be that you are facing a case of the light which is on continuously or just flashing.
It means that the onboard diagnostic scan system has detected some fault on the car engine.
The check engine light on your Honda car being on doesn’t mean anything so severe at times because it could just mean that the gas cap is loose or may mean that your engine has developed a very serious fault.
Flashing check engine light means that the fault on the car engine is serious, manageable and need urgent corrective measure but can last the course.
You may, however, need to note that just like in all cases, the check engine light warning whether it lights on or just flashes, does not need to be assumed entirely.
If you have knowledge in car repairs, then you have the responsibility to pull at the nearest stop and fix the fault if it’s a simple one or makes a date with a mechanic help with the fixing.
Reasons why check engine light is on
There can be several reasons as to why your Honda car has the check engine light being on. These usually range from the rather simple reasons to other dangerous ones which if not sorted out may lead to the breakdown of your Honda car entirely.
Before going further, you need to ascertain issues pertaining to the healthy operations of your Honda car as to whether you could be having any leaks on your car engine, whether you have some new installations on your Honda car, the period when your car was used last or whether you took the car for fueling any time preceding the light being on.
When you have looked at all these, you may find that either the check engine light on your Honda car may have been due to some water puddle you went through recently that splashed on the engine.

1) Damaged oxygen sensors – when the oxygen sensor on the car engine fails, the exhaust system is bound to fail and so making the overall objective of the emission control, which is why the car is fitted with an OBD scanner goes to naught. The additional risk is that the car may consume much fuel than the anticipated.
2) Issues with the gas cap – the gas cap, which at times may even be forgotten after fueling may be what it is all about. Fixing this is as easy as just parking and getting to check if the cap is loose or is even missing, fix it and the light will just be off.

Because these spark plugs are that important, they are usually made to vary on the diverse Honda brands. The spark plug fault needs to be repaired immediately as the malady may spread to other areas of the Honda car engine.

6) The check engine light on the Honda will be cleared with n risk of having to lose the radio stations.
Just like disconnecting the battery with lots of benefits, you get your light removed.
