How to solve the fault of GAC Chuanqi emission system

Clean the throttle or replace the throttle, replace the fuel and replace the oxygen sensor.

1. Clean or replace the throttle valve: the throttle valve will accumulate carbon or be blocked, resulting in the failure of the exhaust system. Cleaning or replacing the throttle can solve this problem.

2. Replace fuel: If the fuel quality is poor or polluted, it may lead to the failure of the emission system. Replacing clean fuel can solve this problem.

3. Replace the oxygen sensor: The oxygen sensor is an important part in the exhaust system, which is used to monitor the oxygen content in the exhaust gas. If the oxygen sensor is damaged or fails, the exhaust system will fail. Replacing a new oxygen sensor can solve this problem.
