What to Do If the Vehicle Fails the Environmental Inspection?

The new traffic laws stipulate that in urban restricted areas, any vehicle without an environmental label or subject to environmental restrictions will be prohibited from entering restricted road sections. Below are the methods to address a vehicle failing the environmental inspection: 1. Conduct maintenance on the engine; 2. Clean and revive or replace the poisoned three-way catalytic converter. Below is additional information on vehicle environmental inspections: 1. For small cars, blue-license vans, and new vehicles, inspections are required every two years for the first six years after registration; after six years, inspections are required annually; after fifteen years, inspections are required twice a year; 2. For trucks, inspections are required annually after registration; after ten years, inspections are required twice a year; 3. The documents required for the annual vehicle inspection include: the vehicle's registration certificate, a valid compulsory insurance policy, and the vehicle and vessel usage tax; 4. If the engine reaches its service life or the vehicle's design does not meet current environmental standards, it must be taken out of service.
My car failed the environmental test during the annual inspection, which was quite a headache at the time. But I immediately went to a local repair shop. The mechanic checked the exhaust system and found that severe engine carbon buildup and aging spark plugs caused the excessive emissions. We replaced the spark plugs, cleaned the engine, and added some fuel additives, costing a few hundred yuan. It passed the retest in one go, and the cost was much lower than expected. Now I pay more attention to car maintenance, changing the oil and air filter every six months to keep the engine clean. I’ve also adjusted my driving habits—avoiding sudden braking and driving smoothly to reduce pollution. If you encounter similar issues, don’t panic. Find a trusted repair shop to check small components; environmental problems can be easily solved and even save fuel costs. Prevention is key—don’t wait until the annual inspection to address issues.
When my car failed the emissions test, I decided to troubleshoot it myself, starting with the simplest steps. I removed the air filter and found it clogged with black debris—replacing it improved the test readings slightly. Next, I checked the oxygen sensor data, which showed abnormal readings, so I installed an affordable universal replacement. I then added a bottle of catalytic converter cleaner to the fuel tank and drove a few hundred kilometers to clear carbon buildup. Along the way, I picked up some DIY tips, like regularly checking tire pressure to ensure optimal combustion efficiency. The entire fix cost less than 500 yuan, and the retest passed. My advice: keep basic tools like an OBD scanner to read trouble codes, avoid rushing into expensive part replacements, and leverage online tutorials—it saves money and feels rewarding. Never overlook small details; even older cars can meet standards with proper care.
Vehicle failing environmental standards harms air quality, which I take very seriously. When my car didn't pass the test, I immediately consulted the environmental hotline and followed their advice to upgrade my vehicle. First, I cleaned the intake tract and replaced it with a high-efficiency three-way catalytic converter to reduce nitrogen oxide emissions. I usually drive in eco-mode, maintaining a steady speed to save fuel. After the repairs, not only did it pass inspection, but the exhaust became cleaner, contributing to emission reduction. I recommend everyone choose low-emission vehicle models to protect our planet – small actions accumulate into great benefits.
The emissions test failed, so I took a cost-effective approach. Starting with the cheapest fix: replacing the oil filter cost 80 yuan, then adding fuel additive to clean the injectors, which only cost a few dozen yuan. After no improvement, I replaced the aging spark plugs. The total cost was kept under 300 yuan, saving a lot by avoiding the dealership. Comparing repair costs versus a new car, fixing it once can last several years, making it more economical. My advice: don’t rush into major repairs—test small fixes first and compare quotes from multiple shops to save money and hassle.
