Common Reasons Your Check Engine Light May Be On


One of the most common reasons for a check engine light to turn on is a loose gas cap. Check to make sure your fuel cap is secured and not damaged or in need of replacement. If the check engine light illuminates when you are towing a heavy trailer or payload, try reducing the weight to see if the light turns off.

If neither the fuel cap nor your towing capacity is the issue, there are other problems that may need to be addressed within your engine. The following are some of the most common reasons your check engine light may have turned on:

Ignition Coils and Spark Plugs

Ignition coils use electricity generated from the battery, allowing your spark plugs to fire. Spark plugs are essential for allowing your engine to run correctly, so if either of these components is old or compromised you may have engine issues and may not even be able to start your car.

Oxygen Sensor

An oxygen sensor monitors exhaust as it exits the engine and measures fuel mixture. A damaged oxygen sensor can affect your exhaust system and engine timing.

Catalytic Converters

Catalytic converters reduce your car’s emissions. If a catalytic converter is not functioning properly, you may be producing high emissions and even affecting your own health by contaminating air quality within the cabin.Honda Service Miami


Your car’s thermostat is vital for regulating the flow of coolant to the engine. Coolant aids in maintaining the internal temperature of your engine so it is not too hot or too cold which can result in decreased fuel efficiency, loss of power, and increased wear and tear.

If your check engine light turns on, the best course of action is to take your vehicle to a service center to be inspected by an experienced technician. Ignoring a check engine light can cause damage to your engine over time, so it is important to have your car inspected as soon as possible.
