Revolution Sensors
Mitsubishi FUSO®

Revolution sensors, also known as crankshaft position sensors, are electronic devices that monitor the rotational speed and position of the crankshaft in an internal combustion engine. They provide critical information to the engine control unit (ECU), allowing it to accurately time ignition and fuel injection events. The ME738936 revolution sensor is a specific part number used in certain truck models and is designed to withstand the harsh operating conditions of heavy-duty vehicles. It is typically mounted on or near the crankshaft and uses a magnetic or Hall-effect sensor to detect changes in the magnetic field caused by passing teeth on a reluctor wheel. This information is then sent to the ECU, which uses it to precisely control engine performance. A faulty revolution sensor can cause a variety of issues, including rough idling, misfires, and even engine stalling.
