QC002104
Crankshaft Position Sensor
Mitsubishi FUSO®

The crankshaft position sensor (part number QC002104) is an important component of a truck's engine management system. It detects the position and speed of the crankshaft, which in turn helps to control the timing of fuel injection and ignition. This sensor works by using a magnetic field to detect the rotation of the crankshaft, and then sending a signal to the engine control module (ECM) to adjust timing accordingly. A faulty or failed crankshaft position sensor can cause a variety of problems, including rough idling, poor acceleration, and even engine stalling. Therefore, it is important to regularly maintain and replace this component as needed to ensure proper engine function.
