Engine RPM / Crankshaft Sensor (Magnetic Pickup) Thermo King Part 44-9298 / 449298

The Engine RPM Sensor Thermo King 44-9298 (Magnetic Pickup / Crankshaft Speed Sensor) is a highly sensitive inductive component engineered to monitor the rotational speed of the diesel engine. Mounted in close proximity to the flywheel, it continuously counts the passing gear teeth and transmits real-time RPM data directly to the unit's microprocessor. This data is absolutely vital for proper engine management.

Without accurate signals from the RPM sensor, the microprocessor cannot properly regulate engine speed (switching between high and low speeds) or manage the starter motor engagement. Sensor failure—often caused by internal coil fatigue or wiring damage from constant engine vibration—results in start failures, erratic engine operation, and immediate RPM circuit alarms. Installing this reliable 44-9298 replacement sensor restores perfect synchronization between the engine's mechanics and the digital controller. The sensor features a threaded metallic body for precise air-gap adjustment.

This critical diagnostic part is listed under the catalog reference 44-9298 and carries the factory component markings 1189A70G03 and 5MT2005 1121PT.
