What are the serious causes of the SAIC Maxus V80 China VI emission system failure?
1 Answers
Here are the specific reasons for the serious failure of the SAIC Maxus V80 China VI emission system: 1. Exceeding OBD standards: Catalytic converter efficiency, particulate filter efficiency, oxygen sensor degradation curve, engine shaking or stalling, evaporative emission control system, fuel system passages, exhaust gas recirculation system—if any of these exceed the standards set by OBD, an emission system failure will occur. 2. Vehicle shaking or stalling: If the vehicle shakes or stalls, the main reason is likely dirty fuel injectors. Long-term use of fuel additives can help eliminate fuel impurities deposited near the fuel injectors. If this doesn't work, take the vehicle to a repair shop to clean the air intake system.
