What Does Emission System Malfunction Mean?
1 Answers
An emission system malfunction refers to issues in the fuel supply system, ignition system, etc., causing engine overheating or backfire, which leads to sintering and peeling of the three-way catalytic converter substrate, increased exhaust resistance, and other problems. Here are some precautions for vehicle emission testing: 1. Use higher-quality fuel in advance: Before the emission test, try to use up the existing fuel in the tank and refill with higher-grade fuel from a reputable gas station. This can help improve emission test results. 2. Inspect and replace the exhaust pipe if necessary: If the vehicle has been used for a long time and the exhaust pipe shows signs of corrosion, it is advisable to inspect and repair it promptly or replace it if needed. A severely corroded exhaust pipe often makes it difficult to pass the emission test. 3. Utilize insurance company assistance for emission testing: Many insurance companies offer vehicle inspection cards as part of their policies, which can help with emission testing and other inspection processes, making it more convenient. Special channels provided by insurers can also facilitate a smoother emission test. Be sure to check with your insurance company in advance to confirm if they assist with emission testing.
