Top Reasons Why Your “Check Engine Light” Has Turned On

While you might believe that the ‘check engine light is a stern indicator of a mechanical issue with the vehicle’s engine, sometimes it can be even more than that. The warning light can also pop up due to a minor glitch in the electrical system of the car. The ‘check engine light is triggered when the vehicle’s ECU detects any error from one or more than one sensor present inside your vehicle.

In this comprehensive guide, we’ll be sharing some of the major reasons why the ‘check engine’ light turns on and how the same can be fixed. 

Reasons Why The Check Engine Light Has Been Triggered And The Ways To Fix The Same

  1. The Car Engine Is Suffering From Lubrication Issues

According to a reliable mobile car mechanic in Sydney, the engine needs oil to be able to keep all its moving parts running smoothly. However, when the engine oil gets dirty or depleted, the oil pressure reduces, and the friction between the engine’s mechanical parts increases. As a result, the ‘check engine light turns on. 

In case you’re unaware then you must know that an unlubricated engine can easily heat up and thereby cause internal damages. Thus, it’s essential to get them checked by a professional mechanic, so that you can enhance the longevity of your vehicle engine.

  1. The Mass Air Flow Sensor Has Been Damaged

The mass airflow sensor inside your car engine is responsible for mixing the correct amount of air & fuel so that a proper combustion process can take place. It’s responsible for maintaining efficient & clean combustion inside the engine. 

So, if in any case the mass airflow sensor malfunctions or gets damaged, it will send a signal to the ECU and thus the ‘check engine’ turns on, letting you know that the sensor must be replaced or repaired. 

Some of the other signs of the mass airflow sensor failing are:

  • Engine stalls just after it has started.
  • Engine hesitating to accelerate.
  • Engine not running smoothly.

The easiest way to fix such a problem is to get your vehicle inspected by a skillful mechanic. The mechanic will be able to determine whether the mass airflow sensor needs to be cleaned or replaced. 

  1. Problems With The Ignition Coil Or Spark Plug

Just like the name suggests, the spark plug is responsible for transferring electrical energy from the coil to the spark plug. Without the spark plug, the fuel & air mix inside the engine will not ignite. Thus, a malfunctioning spark plug will easily trigger the ‘check engine light. The best way to solve this problem is to replace the spark plug.
