When a check engine light pops on while you are on the road, it may be due to something as simple as low window washer fluid, or something as major as a dying car battery. When the check engine light comes on it helps alert the driver that there is a problem detected. It is strongly recommended to investigate the check engine light when it is on even if the problem poses no problem to your vehicle operating system. Citywide Towing Service would like to share some of the reasons why a check engine light will come on and why it is important to seek maintenance or repair before you continue to drive on the road.
Oxygen Sensor Failure
The oxygen sensor or also known as the O2 sensors, help manage the emissions. It is important to manage the emissions the vehicle produces to help keep the engine running and running efficiently. For the engine to run at maximum efficiency, the engine requires an exact ratio of air and fuel. If the sensor fails, the engine efficiency will be compromised and prevent the vehicle from running at all. When the O2 sensor begins to fail or has failed, the check engine light will come on.
Ignition Coil Issues
The ignition coil is designed to ignite the spark plug that will then start up the engine. The ignition coil controls the electrical current from the car’s battery to the spark plug making sure the proper amount of electricity is sent to the spark plug. The ignition coil will develop wear and tear over the year and will need to be replaced. When the ignition coil shows signs of wear, often that will trigger the check engine light.
Spark Plug or Wiring Issues
The spark plug or the electrical wiring that helps start up the vehicle’s engine can wear down and corrode. If the engine has been sluggish, takes time starting and your check engine light has come on, it may the spark plug or the wiring has been damaged and or compromised. If left alone, you may soon find you are unable to start your vehicle.
Mass Airflow Sensor Failure
The vehicle’s mass airflow sensor measures all of air that come into the vehicle’s engine and also calculates how much fuel to add to the mix. If this sensor goes out the Engine Control Unit cannot maintain the perfect balance of air and fuel. As a result, your engine will lose efficiency and develop other problems. When the sensor goes out, the check engine light will come on.
Dying Battery and Charging System Failures
Most modern vehicles will use a computer system to monitor the voltage that is in a battery as well as the electrical system. When the battery and the electrical system begin to deplete its voltage, the check engine light will pop on. The light will help warn you that you will either want to recharge your battery or replace it. If the battery is over four to five years old, you may be looking into a new battery for your vehicle.
