What are the symptoms and manifestations of a broken motorcycle sensor
Author:
Water temperature and oxygen sensor malfunction
Water temperature sensor: The fault light is constantly on, and the water temperature gauge always displays a maximum value of 120 degrees Celsius or the pointer does not move. Difficulty starting a cold car, weak acceleration accompanied by backfire phenomenon, unstable idle speed, and the actual water temperature may be too high but there is no prompt on the instrument panel.
Oxygen sensor: The engine power has significantly decreased, the acceleration response has deteriorated, and riding feels "dull". The fuel consumption has significantly increased, the exhaust emissions are not up to standard, and the engine shakes or even stalls at idle.
Position and speed sensor malfunction
Crankshaft/Camshaft Position Sensor: Difficulty or inability to start, intermittent stalling during driving, shaking or complete immobility of tachometer pointer.
Throttle/intake sensor: Poor acceleration performance, easy to stall at idle, black smoke emitted during high-speed operation, high fuel consumption. If the oil pressure sensor is broken, the oil pressure light will remain on and the displayed pressure value will be incorrect.
General alarm and driving impact
Fault alarm: After the electronic fuel injection motorcycle sensor malfunctions, if the ECU cannot receive the correct signal, a fault alarm will be triggered, and the instrument panel engine fault light will remain on.
Driving impact: In addition to power and fuel consumption issues, it may also cause the ECU to control the fuel injector to stop working, making it impossible to start the vehicle at high temperatures, posing a safety hazard. It is recommended to check and replace in a timely manner when the above symptoms occur.
