Understanding Why Your Check Engine Light is On

check engine lightHave you recently noticed the check engine light on your dashboard? Unfortunately, it’s not always easy to identify the cause of this warning light on your own. You’ll need to take your vehicle to a professional auto technician so he can identify why the light has activated. Do not continue to use your car when this light is activated. Sometimes the issue is minor, but this isn’t always the case. Driving your vehicle when there’s a mechanical issue can make the problem worse, resulting in more expensive repairs. While an auto repair specialist can run an engine diagnostic to determine the exact cause, here are several possible reasons the light may have activated.

Damaged or Missing Gas Cap

One possible reason that the check engine light has activated on your car is that you have a damaged or missing gas cap. This is a very minor issue and can be dealt with quickly at an auto service shop.

Broken Spark Plug

Broken spark plugs can also cause your check engine light to activate. This will generally result in issues starting your vehicle. If this is something you’ve noticed, take your car in for auto repair right away.

Malfunctioning Mass Air Flow Sensor

Your engine uses fuel and oxygen to function. The mass air flow (MAF) sensor determines the proper ratio. These can break, be knocked loose, or become too dirty to work. You’ll need professional car maintenance to fix this problem.
