How to Diagnose a Check Engine Light?

The check engine light is a significant component of your beloved vehicle. Though many may find it annoying, it is actually very useful. Whenever it comes on, it alerts that something is wrong with your car and you need to troubleshoot it soon with a Check Engine Light Diagnosis. The check engine light indicates serious issues if it flashes and a less significant issue if it lights steadily. In any case, fixing it quickly may not only sort the issue, but also save the money and avoid further damage. Listed below are the issues a check engine light may indicate:

1. Faulty Oxygen (O2) Sensor

The function of the O2 sensor is to measure the amount of fuel burnt in the exhaust system. In case of no replacement, the faulty sensor may consume extra fuel and cost you extra money. It may cause further damage to components, such as spark plugs as well as a catalytic converter.

2. Loose or Damaged Gas Cap

The use of a gas cap is to seal the fuel system and keep the gas pressure intact inside. In case of damage, it lets air pressure evaporate causing overconsumption of the fuel.

3. Bad Catalytic Converter

The catalytic converter protects the health of your vehicle by converting carbon monoxide, which is a harmful gas, to carbon dioxide. It usually happens if a certain issue, such as a fault in the oxygen sensor, remains unresolved. A bad catalytic converter may lead to reduced performance of the vehicle and it is expensive damage.

4. The issue with the Mass Airflow Sensor

The function of the mass airflow sensor is to analyze the amount of air enters the fuel engine and determine the quantity of fuel needed. It needs a quick repair or else it damages other components, such as spark plugs and catalytic converter.

5. Spark Plug Issues

The main aim of spark plugs is to ignite the air/fuel mixture inside the combustion chamber. Faulty spark plugs may give rise to a number of issues related to poor performance and receded fuel economy.
