Automotive,Research,Self Improvement Oh no, your check engine light just came on! When the check engine light comes on, most always, we start to panic in fear that our car is going to shut off right then and there or worry over the thought of how much money it may cost. But no matter what, when a check engine light comes on, it means that there is most definitely something wrong under the hood. Here are the most common issues associated with a check engine light in Davis County. Oxygen Sensor: An oxygen sensor measures the unburned oxygen in your vehicle's exhaust system. The data of which it presents sends information for the regulation of the mixture of air and fuel that enters the cylinders. A bad oxygen sensor can damage spark plugs, the catalytic converter, and burn more fuel.
Loose Gas Cap: If the gas cap is loose or missing, the check engine light will turn on. It is very important to make sure your gas cap is secured tightly so that fumes are not released into the air, which helps to keep the whole system under the correct pressure. It is probably your gas cap if the check engine light turns on right after you put gas in. Catalytic Converter: A catalytic converter helps with converting carbon monoxide into carbon dioxide. If your catalytic converter does not get replaced, your vehicle will not pass emissions, will experience reduced performance and fuel economy, and your car may run at a higher temperature. Mass Airflow Sensor: The mass airflow sensor measures how much air enters the engine to determine how much fuel is needed to run your engine. You may notice that your mass airflow sensor is not working if you are experiencing a rough idle, the car is having trouble starting, and a sudden change in the position of the throttle pedal.
Spark Plugs or Plug Wires: Your spark plugs ignite the air/fuel mixture in the combustion chamber of your vehicle, and the spark plug wires deliver the spark from the ignition coil to the spark plugs to make this happen. If the spark plugs or wires are not replaced, you will notice misfire and the hesitation under heavy acceleration, a possibility of a clogged catalytic converter, damage to ignition coils and O2 sensors.
