How to solve the Roewe RX5 engine emission fault?
2 Answers
Engine emission faults are related to the oxygen sensor, which may be a false fault code of the oxygen sensor. If so, clearing it will suffice. The fault may also be related to the quality of the fuel added, causing inaccurate data monitored by the oxygen sensor. A diagnostic tool is required to determine this. When an engine emission fault occurs, the owner should promptly clean the engine. To maintain the engine in good working condition, using 95 or 97 octane gasoline can help resolve engine emission faults.
The engine emission warning light on the Roewe RX5 is a common issue. I've encountered it several times while using the car, usually due to a faulty oxygen sensor or a clogged catalytic converter. You can buy an OBD scanner to read the fault codes yourself and identify the specific problem. For example, the last time my car's light came on, it showed a P0420 code, indicating low catalytic efficiency. I tried cleaning the converter with a cleaning agent, but it didn't help much, and I ended up replacing the part at a repair shop. Remember to perform regular maintenance, check the air filter and fuel quality, and use high-quality gasoline to reduce emission faults. Prevention is key—don't wait until the problem worsens to address it. Be careful when working on the car yourself, and avoid disassembling engine components recklessly. My experience over years of driving tells me that timely action can save a lot on repair costs and extend your car's lifespan.
