What Are The Most Common Reasons Your Check Engine Light Is On?
Don’t know why your check engine light is on? Before you panic, know that there are a lot of reasons behind this. That’s why it’s important to know each and every cause – so that you know what to do in case it happens.
Here are several reasons why your check engine light is on:
Engine Issues
Engine problems, of course, would trigger this sensor. When this happens, the control module has detected something faulty in the engine operation. As such, it will alert you of this event right away.
Transmission Issues
Your car’s transmission manipulates your engine power and channels it to your wheels. The two work together which means that transmission problems cause engine issues. Expectedly, this problem will turn your check engine light on.
Ignition System Problems
The ignition system includes coil packs, spark plugs, and other devices that help ignite your engine. Problems in any of these parts will cause the control module to alert you right away.
Air & Fuel Delivery Concerns
A car needs the right mix of air and fuel to perform well. Too much (or too little) of any will alert the control module, which will then inform you by turning on the check engine light.
Emission Equipment Problems
If you drive a new vehicle, then it most probably has emission devices such as the catalytic converter, the evaporative emission system, and the exhaust gas recirculation system, to name a few.
That said, a failure in any of these will need checking – which is why your car turned its check engine light on.
The most common emission related issue is from a loose gas cap. So check that first.
Electronic Powertrain Control Issues
Powertrains function with the help of several sensors and controls. Should these parts trip, your car will alert you to the problem through the check engine light.
What To Do When The Check Engine Light Flashes?
If your check engine light is solid in color, then it means that you have some time before you need to take your car to the auto repair shop.
But if it’s flashing, then you should seek out professional help immediately. Don’t try to drive it as this may lead to an accident.
