Here are some common things that might cause your check engine light to turn on:

Loose or Old Gas Cap

A loose gas cap is one of the most common reasons why a car’s check engine light switches on. Often the gas cap has to be replaced, but it's not a crisis that will hit your wallet hard.

Oxygen Sensor Failure

The oxygen sensor tests the amount of unburnt oxygen in the car exhaust system and sends the data to the vehicle's computer. The engine will still work even if the O2 sensor needs to be replaced, it will cause your care to burn more fuel than usual.

Catalytic Converter Failure

The catalytic converter is built into the vehicle's exhaust system, and its failure can often be avoided. Performing routine maintenance is crucial to keeping your car's catalytic converter in working order.

Ignition Coil Issues

The ignition coil produces the electricity needed by the spark plugs to ignite the fuel and air mixture. A malfunctioning ignition coil would almost certainly cause the engine light to turn on.

Bad Spark Plugs

A spark plug passes electricity from the ignition coil to the spark plug, and without them, the combination of fuel and air in the cylinders will not be ignited. Symptoms of bad spark plug wires include rough idleness, a significant drop in engine output, and lower gas mileage.

ass Airflow Sensor Failure

The mass airflow sensor controls how much air enters the engine and is part of the engine management system. Symptoms of a mass airflow sensor failure include extreme idleness, difficulty starting, and abrupt change in the direction of the gas pedal.

Aftermarket Alarm Issues

An aftermarket alarm can cause havoc on your car if it's not installed correctly. If you are experiencing any electrical issues and have an aftermarket alarm system installed in your vehicle, that may be the cause.

Vacuum Leak

Every car has a vacuum system that performs a broad range of functions. If your vehicle idle starts to surge or settle at an extremely high RPM, a vacuum leak could be the cause.

Exhaust Gas Recirculation Valve Failure

The exhaust gas recirculation valve decreases the amount of nitrogen oxide that comes out of the car engine and allows it to operate more effectively. Luckily, replacing the valve is something you can do at home, or you can schedule a service appointment to have a mechanic do it for you.
