What If You Don't Pass the Vehicle Emission Test? Here Are the Causes and Solutions!
Many people wonder what happens if they fail the emission test? So, what actually causes this failure and what are the solutions? Well, to find out, let's look at the explanation below.
Causes of Failing Vehicle Emission Tests
Here are various reasons why vehicles fail the emission test.
1. Incorrect Oil Product or Late Change
The first reason for failing is that the vehicle's oil does not meet recommendations. To see the recommended oil, you can check here.
Additionally, this mistake can also occur because the owner has performed routine oil changes, resulting in poor engine quality.
Basically, oil has its own viscosity level, so it needs to be matched to the vehicle manufacturer. Incorrect oil can lead to incomplete combustion, resulting in high emission residues.
2. Careless Fuel Use
In addition to oil issues, incomplete combustion is usually caused by carelessness in choosing fuel. It is important to note that fuel with an incompatible compression ratio can increase HC, CO, and NOx emissions.
This means that the choice of fuel must match the engine compression to produce environmentally friendly emissions. One of the best recommendations is fuel with a sulfur content of less than 50 ppm and compliant with EURO 4 standards.
3. Clogged Injector
A clogged injector is also a reason why emission tests fail. This component plays a crucial role in spraying fuel into the combustion chamber. When it is clogged with dirt, the engine's performance can be affected.
Often, such clogs can also make the vehicle consume more fuel. This can be seen by the appearance of black smoke, indicating that the vehicle's emissions are not perfect.
4. Leaking Exhaust
Another reason a vehicle fails the test is due to issues with the exhaust. As is known, the exhaust is the outlet for the remnants of combustion in the engine or engine roof.
Therefore, when the exhaust leaks, the vehicle may experience problems with emission disposal. Essentially, the exhaust is one of the components that is quite vulnerable to leaks and corrosion.
Such conditions can reduce the pressure of the exhaust gas circulation. As a result, the engine performance that should run smoothly becomes disrupted. Ultimately, the emissions from the exhaust gases will increase drastically.
5. Neglecting Maintenance
Finally, one reason for high emissions from exhaust gases is that vehicle owners are lazy or rarely perform routine checks or maintenance. In fact, this habit is important to ensure the vehicle remains in optimal condition.
During maintenance, technicians will conduct a thorough inspection of the vehicle's condition. If there are any issues, replacements or repairs will be made immediately.
Therefore, when maintenance is infrequent, the condition and performance of the vehicle will be suboptimal. As a result, the exhaust gases produced will have high emission levels, leading to failure in the emission test.

What If the Vehicle Fails the Emission Test?
After knowing the causes, what should be done if the emission test fails? The easiest solution to address this is to perform maintenance.
This step can make a vehicle that previously had suboptimal combustion processes perform well again. Maintenance can be done at places like official Daihatsu workshops to ensure optimal results.
Those are some things to know about what to do if you fail the emission test and the various causes of failure. Pay attention to these matters so you can continue to drive comfortably without causing air pollution.
