Can Car Still Show Code If Engine Light Off [Explained]

Yes, a car can still show codes even if the check engine light is off. The check engine light is a warning light that indicates that there is a problem with the engine. However, there are many other codes that can be stored in the car’s computer that do not trigger the check engine light. These codes can be related to emissions, transmission, or other systems in the car. If you are having problems with your car, it is a good idea to have it scanned for codes even if the check engine light is not on.

So Can Car Still Show Code If Engine Light Off?

However, there are many other problems that can occur with a car that will not trigger the check engine light, such as a bad alternator or a misfiring spark plug. If you are having problems with your car, even if the check engine light is off, it is still a good idea to have it checked out by a qualified technician.

In some cases, the CEL may come on for a short period of time and then turn off again. This is usually because the problem that caused the CEL to come on has been fixed.

However, if the CEL comes on and then turns off, it is still a good idea to have your vehicle checked by a mechanic. This is because there may be a problem with your vehicle that is not causing the CEL to come on, but could still cause problems down the road.

Once you have a scan tool, you can connect it to your vehicle’s OBD-II port. The OBD-II port is a standardized port that is located under the dashboard of most vehicles. Once you have connected the scan tool, you can read the codes stored in your vehicle’s computer.

What to Do If Your Car Still Has a Code

You can have your car fixed by a mechanic. Your mechanic will be able to diagnose the problem and fix it.
