What can be the reason behind failed emission test?

There can be several factors behind failed emission tests. However, some of the most common reasons can range from the quality converter to damaged fuel injectors. 

Issues with a faulty exhaust system due to wear and tear and extreme weather conditions can result in poor fuel efficiency, engine noise, or excessive vibration. If you can recognize the cause of failed emission tests, you can have a smoother and quieter ride with better efficiency. Most importantly you can reduce harmful effects on the surroundings. 

  • Oxygen sensor malfunction: The oxygen sensor is present in all types of exhaust systems and measures the quantity of oxygen gas in the exhaust. Oxygen sensor malfunction is very common and can happen due to various reasons. The oxygen sensor is not able to measure the amount of oxygen gas due to leakage. It results in harmful fumes passing through. The condition is likely to prevent your car from passing the emission test. You may also find a problem on the dashboard or through an onboard diagnostic test.  A failed oxygen sensor can result in engine overheating, loss of power, and toxic fumes from the exhaust. 
  • Damaged exhaust system: The catalytic converter is responsible for converting harmful hydrocarbons into cleaner gases. Check the catalytic converter for damage to make certain that the metals are intact. These are responsible for converting toxic gases into clean emissions. If the catalytic converter is damaged, your car will not pass the emission test.
  • Issues with the ignition system: Vehicles often fail in emission tests due to the presence of high volumes of toxic hydrocarbon in the fumes. This can be a result of a faulty ignition system. The ignition mechanism in your car comprises fuel injectors, spark plugs, ignition timing belts, and other components. If the car does not get proper maintenance, it is most likely to develop problems with the ignition system. You need to check for worn-out spark plugs, High tension spark plug leads, advanced ignition timing, or dirty injectors. 
  • Overdue for an oil change: Your car may not pass the emission test because the oil has not been changed at the right interval. The owner’s manual specifies the period to change the engine oil. If it is not done at the right time, your car will fail the emission test. Dirty oil inside the engine crankcase can cause additional pollutants in the exhaust system. Fresh oil reduces the number of contaminants, raw gas vapors, and hydrocarbons. 

These are some of the reasons that your vehicle failed the emission test. It is also a signal that the car engine is emitting more pollutants into the environment. Consult with a service technician at Mysyara to have a better idea of what components to replace or repair.
