What is the reason for the flashing EFI warning light on the CFMoto 150nk?

CFMoto 150nk EFI warning light flashing indicates a fault in the ECU (Electronic Control Unit). For models equipped with F1 warning light: In models with F1 warning light, when the F1 light flashes, it means the ECU has detected a fault. Not all detected faults will flash during power-on self-test; some faults require engine operation before generating error codes, such as MAP sensor failure. F1 light flashing frequency and count represent error codes: The flashing frequency and count of F1 light represent error code numbers. Different manufacturer systems have different settings, and the same code number may indicate different faults across systems.

Seeing the fuel injection warning light flashing on my CFMoto 150NK, I always feel this shouldn't be delayed. As an experienced motorcycle rider, common causes include sensor failures such as oxygen sensors or throttle position sensors malfunctioning, the electronic control unit (ECU) throwing error codes, or clogged fuel injectors causing poor fuel delivery. Loose wiring connections are also common, as vibrations can loosen connectors over time. Once the light flashes, it's best to stop immediately and avoid forcing the ride, otherwise you risk stalling mid-journey which can be dangerous. I recommend first checking vulnerable components like fuses or wiring connections, then taking it to a professional repair shop to read the fault codes with a diagnostic tool for targeted solutions. Regular maintenance should include periodic fuel system cleaning and battery checks to prevent minor issues from becoming major problems.

I just bought a CFMoto 150NK and soon encountered a flashing malfunction indicator light. After checking a lot of information, this situation may indicate a problem with the fuel injection system, such as unstable fuel pressure or a sensor error. I tried some simple checks myself, like seeing if the battery terminals were loose or if the fuel injector was dirty, but beginners shouldn't disassemble things randomly as it could make things worse. In this case, I suggest borrowing a diagnostic tool from a friend or going directly to a 4S store for inspection. Don't try to save trouble by riding it forcefully—sudden engine shutdown can be very dangerous. Regular maintenance, such as cleaning filters and fuel lines, can prevent many issues.

When the malfunction indicator light flashed while riding the motorcycle, I immediately became alert. Generally, this indicates an abnormality in the fuel injection system, such as an oxygen sensor fault, ECU error, or ignition coil failure. Connecting a diagnostic device can quickly identify the cause. Don't delay repairs, as it may increase fuel consumption and potentially damage the engine. You can also perform a preliminary check yourself to see if the wiring harness is damaged.
