What Causes the Check Engine Light To Light Up?

The Check Engine Light turns on when the ECU, or Engine Control Unit, notices that something is not as it should be. The ECU is a computer that relies on several sensors to keep an eye on engine and emissions functions. When one of these sensors gives the ECU an abnormal reading, the ECU will store a code and turn on the Check Engine Light. Below, you will find some of the more common reasons the Check Engine Light may come on; however, there are many more possibilities.

Loose, Damaged or Missing Fuel Cap
Oxygen (O2) Sensor Failure
Damaged Catalytic Converter
Faulty Mass Air Flow (MAF) Sensor
Spark Plug Trouble
Exhaust Gas Recirculation (EGR) Valve Failure
Battery Trouble

Check Engine Light Diagnostic Service at Tate Chrysler Jeep® Dodge Frederick

When the Check Engine Light turns on, the ECU will store a code pointing to the faulty system or component. The technicians at Tate Chrysler Jeep® Dodge Frederick can hook your vehicle up to a code reader, which will let them know where to look.

How To React When the Check Engine Light Turns On

If the Check Engine Light is solid and illuminated, you should make your appointment as soon as possible. After all, it does mean that there is an issue that may affect your vehicle's performance, fuel efficiency, or emissions. However, it's likely not an emergency, and you can finish your drive before making your appointment.

A flashing Check Engine Light, on the other hand, generally means that the engine is misfiring, which can cause extensive damage to the catalytic converter. In cases like these, you should pull over and call for a tow truck as soon as you can safely do so.
