ME241121
Engine Speed Sensor Pulse Rotor
Mitsubishi FUSO®

The Engine Speed Sensor Pulse Rotor, also known as the reluctor wheel, is a component that is located on the crankshaft of an engine. This part is responsible for generating a signal that is used by the engine control module to determine the speed and position of the crankshaft. The ME241121 model is a specific part number for this component. As the engine rotates, the teeth on the rotor pass by the engine speed sensor, which then sends a signal to the ECU. This information is used to control fuel injection timing and ignition timing, ensuring optimal engine performance. A faulty Engine Speed Sensor Pulse Rotor can cause misfires, poor acceleration, and even stalling. It is important to regularly inspect and replace this component as needed to maintain proper engine function.
