What are the causes of the emission control system malfunction in the Avancier?
2 Answers
The emission control system malfunction in the Avancier is due to poor fuel quality. Handling false faults in the emission control system: Start and turn off the Avancier three times in a row, or disconnect the negative terminal of the engine battery, wait for 30 seconds, and then reconnect it to see if the engine fault light on the dashboard is still on. Causes of emission control system malfunction: The emission system fault light in the Avancier often lights up due to poor fuel quality in China, damage to the oxygen sensor in the three-way catalytic system, or poisoning of the three-way catalytic converter. If this light comes on while driving, it is necessary to immediately reduce speed and drive to the nearest service station for inspection and repair.
I've encountered an emission system malfunction in my Honda Avancier, where the check engine light came on. Upon inspection, it turned out the oxygen sensor had failed, causing inaccurate oxygen measurement and disrupting fuel control. The EGR valve also frequently gets carbon buildup and sticks, leading to exhaust gas recirculation issues. Or sometimes, aging vacuum lines develop leaks, allowing excess air intake that affects the air-fuel mixture. A clogged catalytic converter can also trigger faults. My car has been repaired several times for reasons including sensor contamination and poor fuel quality. I recommend addressing these issues promptly as they increase fuel consumption and emissions, and in severe cases may cause the vehicle to fail emission tests. Nowadays, using an OBD scanner to read trouble codes can quickly pinpoint problems - don't delay repairs until they become expensive.
