How to resolve the yellow engine warning light in Wuling Hongguang?

Engine malfunction light may indicate a serious problem with the engine, or it could simply be due to some sensor damage. After powering on the vehicle, the self-check function will activate. Observe the dashboard for 5-10 seconds to see if other warning lights turn off, leaving only the engine malfunction light. If other warning lights remain illuminated, it is necessary to have the corresponding modules and components inspected at a 4S shop or repair facility.
I've been driving my Wuling Hongguang for several years, and when the engine warning light comes on, don't rush to find ways to clear it. Most of the time, it's a minor issue with the emission system, like a dirty oxygen sensor or a slightly clogged fuel pump. First, you need to buy an OBD scanner to read the fault codes—it's cheap and practical, just plug it into the port to see the specific problem. If it's a common code like P0171, it might be caused by a vacuum leak messing up the air flow; before clearing the code, check if the wiring harness connections are loose. If the light goes off and comes back on, take it to a 4S shop—don't delay until it becomes a major issue. Wuling cars are tough but prone to small problems, so keep an eye on maintenance records and regularly change the oil and air filter to prevent bigger issues. Remember, don't tinker with it yourself to avoid damaging the circuits. The whole process is straightforward in theory, but you need to be careful and take it step by step—ensuring driving safety is the top priority.
