Can a Car Still Show Codes If the Engine Light Is Off?
The answer is yes, a car can still show codes even if the engine light is off. This is because the engine light is only triggered when a certain threshold of severity is reached. There are many other less severe codes that can be stored in the car’s computer even if the engine light is not on.
How to Check for Codes
There are a few ways to check for codes on a car even if the engine light is off. One way is to use an OBD-II scanner. This is a small device that plugs into the car’s diagnostic port and can be used to read codes from the car’s computer. Another way to check for codes is to take the car to a mechanic and have them use their diagnostic equipment to read the codes.
What to Do If You Find Codes
If you find codes on your car, it is important to take them seriously. Even if the engine light is not on, the codes could indicate a potential problem that needs to be addressed. It is best to take the car to a mechanic and have them diagnose the problem and make any necessary repairs.
Conclusion
So, to answer the original question, yes, a car can still show codes even if the engine light is off. It is important to be aware of this and to take any codes that you find seriously. By doing so, you can help to keep your car running smoothly and safely.
