Top 5 Reasons Your Check Engine Light May Be On

Wilmington luxury car care

The check engine light in your vehicle can indicate a number of issues, big or small, so why wait to address it? It could mean that it is time for a preventative maintenance service if accompanied by a specific service warning light on your dash, or it could be something much worse. More often than not, however, the check engine light comes on because there is something wrong with one of the five things listed below. The Wilmington luxury car care experts at Performance Auto Specialists can run a diagnostic test to see why the check engine warning is on and then fix the problem so you needn’t worry about the warning any longer. Here are the top 5 reasons your check engine light may be on:

Catalytic Converter

Hopefully, your check engine warning isn’t coming on because your catalytic converter is going out. The only reason we say this is that it can be expensive to replace the catalytic converter, and your vehicle cannot run without it. The catalytic converter is part of your vehicle’s exhaust system and if you notice a rotten-egg smell along with the check engine warning, this is probably the problem.

Gas Cap

We can only hope that your check engine warning came on because you didn’t screw on your gas cap tight enough the last time you filled up your car, SUV, or truck. A loose gas cap will cue a check engine warning because there should be a vacuum seal created with the cap once you’ve tightened it. If your cap is loose because you didn’t tighten it, cracked, or if the seal is broken, your check engine warning will come on.

Mass Airflow Sensor

The mass airflow sensor in your vehicle’s engine measures the air coming into the engine to make certain the right amount mixes with fuel. If you aren’t getting the right air/fuel mixture, your engine might stall or refuse to start. When the mass airflow sensor fails, your check engine light will come on because the onboard computer received a signal that there is a problem with the air/fuel mixture in your engine.

Oxygen Sensor

The same holds true for the oxygen sensor. This crucial sensor measures how much unburned oxygen is in your automobile exhaust and if there’s too little or too much, it could damage other engine parts. A faulty oxygen sensor will return a check engine warning every time. In fact, it’s one of the most common reasons why a check engine light comes on while you’re driving your automobile.

Spark Plugs

Finally, worn spark plugs or plug wires will result in a check engine warning. Just about anything wrong with your vehicle’s ignition system will likely cause your check engine light to come on. If you haven’t had your plugs changed and your vehicle has over 100,000 miles on it, it’s time for new plugs and possibly new wires.
