Mio j mendadak brebet | deteksi kerusakan dengan scanner MST 200#KakexChannel

Yamaha Mio J Suddenly Struggles, Detect Faults with the MST 200 Scanner To facilitate analysis of fuel injection system damage, a scanner capable of reading data from the ECU/ECM is essential. This time, I used the MST 200 scanner. It's important to understand that using a scanner doesn't immediately reveal the faults in an fuel injection engine. Mechanics must understand the operating patterns of each engine they're working on. Once we understand this, we can compare it with the data read on the scanner. In this case, the Mio J engine suddenly stuttered and wouldn't start. Upon inspection, the AFR (Air Fuel Ratio) was found to be over 16.0, while the ideal air-to-fuel ratio is 14.7. This indicates the engine is experiencing a fuel shortage. The injector spray duration was also observed to be up to 5 ms at idle, compared to the typical 2.5 ms for a normal engine. This means the ECU is attempting to increase fuel supply, striving for the ideal AFR, but its capability is limited to less than 10 ms. Given this situation, we should suspect a disruption in fuel flow. This is not a conclusion, but rather a guess based on the existing conditions. From experience, the most common problems are weak fuel pump pressure and clogged injectors. The fuel pump pressure reading is 3 bar, which is normal. The next step is to try cleaning the injectors. There are several methods for cleaning injectors, and in this video, I clean the injectors using ultrasonic cleaning. After cleaning, the readings showed normal readings. The motorcycle accelerated normally. Hope this is helpful. Address: PRATIWI MOTOR Workshop Jl.
