There are many emotions experienced when the check engine light illuminates. The light is an indication of a varying issues ranging from minor to major. Abnormal sounds coming from the engine, getting lost, or even a challenging blind spot can contribute to feeling overwhelmed when the light comes on. Today, we at Highway 30 Garage would like to share the common reasons as to why the check engine light may come on.
 

Bad Ignition Coil

The source to the check engine light can be ignition coil issues. Ignition coils ignite the spark plugs with the use of an electric current from the car’s battery. In the event there is any impedance with the ignition coil the electric current running through the car is disrupted. The entire electrical system can be impacted if this is the cause and you need professional care.
 

Oxygen Sensor Fail

In order for a vehicle’s engine to operate at maximum performance, the oxygen emissions levels need to be managed. The oxygen sensors gauge the gasses that leave the engine in order to make sure that the correct ratio of oxygen and fuel are being pumped through the engine. When the ratio is imperfect, the fuel economy of the vehicle drops, causing the engine light to pop on.
 

Mass Air Flow Sensor Problems

The check engine light to switch on when the mass airflow sensor experiencing problems. The job of the mass airflow sensor is to measure the correct amount of the air that enters an engine. When the mass airflow sensor is not working properly the engine’s performance significantly drops, and the fuel efficiency can be greatly reduced.
 

Evaporative Emission Control System Leak

The Evaporative Emission Control system (or EVAP) is in place to monitor that the gasoline vapor does not exit the gas time and fuel system as well as releasing into the air. Faulty gas caps can be the cause as well as broken valves or leaking vacuum hoses and vents. The check engine-light will come on to notify you there is an issue, and it will need to be serviced.
 

Spark Plugs & Wires

The electrical problems that sets off the check-engine light from spark plugs and wires not effectively functioning. Permanent damage to a vehicle’s catalytic converter can be the result ignoring problems with spark plugs as they are a vital element to the vehicle’s electrical system. Erratic engine performance like power losses and surges, rough engine idling, and engine misses or pings are produced. To prevent expensive repairs, be sure to get the vehicle checked as soon as possible.
