How to deal with the exhaust emission fault warning of Hongqi HS5?

Clean the throttle body. There is accumulated carbon deposit, so engine carbon cleaning is required. It will become relatively stable as long as the temperature drops to a certain level without fluctuation.
The Hongqi HS5 has encountered an exhaust emission malfunction. I faced a similar issue last month when the dashboard warning light suddenly illuminated while driving, which gave me quite a scare. As the owner, I immediately slowed down and pulled over to inspect the vehicle. Realizing it wasn't something I could fix myself, I headed to the 4S dealership. The technician used a diagnostic tool to read the fault code and confirmed that an oxygen sensor malfunction caused the exhaust system to misread data, resulting in excessive emissions. Common causes of this issue include using low-quality gasoline, sensor aging, or exhaust system blockages affecting emission purification. It's crucial not to delay addressing this problem—visit a professional workshop for diagnosis to prevent further damage, as neglecting it could impact vehicle inspections or even engine longevity. Regular maintenance of the fuel system and using higher-grade gasoline for cleanliness are recommended. Prioritize safe driving—don't cut corners on minor expenses, as timely repairs can save you from major troubles.
The exhaust emission fault of the Hongqi HS5 requires careful analysis. From similar cases I've reviewed, common causes include issues with the oxygen sensor or the three-way catalytic converter, where the sensor detects abnormal exhaust and triggers a warning. Alternatively, unclean fuel mixed with impurities can lead to incomplete combustion. When dealing with this issue, it's advisable not to drive long distances. First, use an OBD diagnostic tool to check the fault code and identify the problem. If no tool is available, visit a repair shop—sometimes a simple sensor cleaning may suffice, while severe cases may require part replacement. Emission faults impact the environment and can increase fuel consumption, making early resolution crucial. Regular attention to fuel quality to reduce impurity buildup is an effective way to prevent such faults and maintain system efficiency.
