Every car owner or driver fears having a check engine light blink on their dashboard. A check engine warning light makes it impossible for a driver to drive. When he looks at the dashboard, he feels dark.
A simple trick to turn off check engine light that you can perform is turning your engine on and off.
Make sure your gas cap is tight since a loose cap can cause your check engine light turn to come on. If the gas cap is tightened, the check engine warning light may go on without disconnecting the battery.
You can turn off your car’s check engine light by removing the engine control unit’s fuse and reinstalling it. Older cars may benefit from this, but newer ones will not. It’s easy to try. Your repair manual will tell you where the fuse is.
