Why does the Tianjian 150's malfunction indicator light come on?
2 Answers
Tianjian 150 malfunction indicator light comes on. Remove the battery cable, wait for half an hour, and then reinstall it to resolve the issue. Reasons: Faults in the fuel supply system, ignition system, intake system, exhaust system, or various sensor components. You can use the elimination method to check each one by one. If the engine light comes on while driving, have the fault code checked at a repair shop. Engine maintenance: The fuel pressure at idle should be around 250 kPa. As the throttle opens, the fuel pressure should gradually increase. The fuel pressure at full throttle should be approximately 300 kPa. If the fuel pressure changes with the throttle opening but remains consistently high, it indicates a fault in the fuel pressure regulator, which should be replaced.
I've had similar experiences while riding motorcycles. When the malfunction indicator light (MIL) on the Tianjian 150 comes on, it's usually a minor issue like a dirty or faulty oxygen sensor in the exhaust system. The sensor monitors engine emissions, and if the signal is abnormal, the light will illuminate. It could also be a fuel-related problem, such as clogged fuel injectors or the use of low-quality gasoline affecting combustion. Another possibility is an ignition system failure, where aged spark plugs cause the engine to run roughly. These are common scenarios I've encountered while helping friends with motorcycle repairs. I recommend first checking if the air filter is clean, as blockages can affect airflow. Don't rush to spend big money – simple issues can often be fixed by replacing a small component yourself. For more complex problems, use diagnostic tools to read the trouble codes; for example, an OBD scanner can quickly identify the exact cause. Timely repairs can prevent more serious engine damage.
