How to Solve the GS4 Emission System Fault?

[DelAmir]

GS4 emission system fault solutions: 1. When the GS4 emission system fails, the engine fault light will illuminate, requiring a computer to detect the engine fault code to eliminate engine faults; 2. Identify the cause based on the fault code. When the engine is not working properly, the exhaust emissions will exceed the standard. The oxygen sensor detects abnormal mixed gas and reports a fault code for checking the emission system; 3. The engine exhaust system fault light is mainly caused by excessive carbon deposits in the throttle or engine interior, leading to an imbalance in the mixed gas ratio; 4. Fuel quality issues. Poor fuel quality can accelerate carbon deposit formation, which in turn causes engine emission system faults. It is necessary to disassemble the intake tract to check if there is excessive carbon buildup.
