CHECK ENGINE LIGHT

Let's Tell You Why Your Check Engine Light Is On.

It can be concerning that while driving, your CHECK ENGINE LIGHT comes on. In most cases it may be fine to continue to drive as long as nothing appears to change in your cars operating performance. You should schedule a professional service call to avoid damage and a larger problem. A blinking light, or red illuminated light instead of yellow or orange indicates there is an IMMEDIATE problem that needs attention.

Common Reasons Why Your Check Engine Light Is ON

1. It could be your CATALYTIC CONVERTER is going out. This can be an expensive repair and your vehicle can not run without it. It’s part of your vehicles exhaust system and may create a ‘rotten egg’ smell.

2. It could be because your GAS CAP might not have been closed correctly or tightly enough the last time you were getting fuel. There should be a vacuum seal when done correctly or the check engine light may come on.

3. The MASS AIRFLOW SENSOR measures air coming into your engine to make certain there is the right amount of mix with fuel. This might cause your car to stall or not start.

4. Similar is your OXYGEN SENSOR. It measures unburned oxygen is in your auto exhaust. If not correct it can impact other engine parts. It is one of the most common reasons the check engine light comes on.

5. WORN SPARK PLUGS OR PUG WIRES will also cause the check engine light to illuminate. Just about anything to do with the ignition system will cause it to come on. If you have 100,000 miles on your vehicle, it’s probably time for new plugs and possible new wires. Car stalling is another indicator or this problem.
