Clearing CEL codes

[The LASER Shop]

If i'm getting a lit check engine light from something like a loose gas
cap, can I clear or reset the code by disconnecting the battery for a
short while?

If it was the gas cap the CEL will go off after 10-20 start cycles. eddie

But if it was something else, can one clear the CEL by taking voltage off
the system for a short while, Eddie?

I'm not Eddie but I know you can take the voltage off to clean the CEL. Your
car's engine computer - ECU - will take sometime to figure out the correct
parameters to run efficiently, those parameters are cleared as well.

If there's something wrong, your CEL will come back again. This time go to
find someone read the error code for you.
