SENSOR - ENGINE SPEED (Doosan DWA138741)

A failing engine speed sensor can cause erratic tachometer readings or prevent the engine from starting. This aftermarket replacement part references the Doosan catalog and carries the cross-reference number DWA138741. The sensor monitors rotational speed of the engine's crankshaft or camshaft to provide input for fuel injection timing. When the sensor fails, the engine may stall unexpectedly or run with reduced power. Keeping the sensor in sound condition helps maintain consistent engine performance under varying loads. Verify the serial number or application, then call (562) 693-7748. The sensor is a generic type that uses a magnetic pickup to detect gear teeth passing by.
