Speed Sensor 3967252 | Essential Spare Part for Cummins Diesel Engines

Product Basic Parameters

Part No.: 3967252, OEM replacement part for Cummins engines. It adopts magnetic induction structure, with standard 5/8-18 UNF thread for direct installation. Internal resistance max 300 ohms, frequency range 50–5000Hz, operating temperature covers -55℃ to 105℃, adapting extreme cold and high-temperature working conditions. The whole sensor is made of anti-rust alloy shell with sealed internal chips, shockproof and dustproof, net weight only 0.05kg, compact size for easy mounting on engine flywheel housing. It matches original signal output standards, no extra modification required during replacement.

Application Range & Usage

This speed sensor fits multiple Cummins engine series: 4B3.9, 6B5.9, 6C8.3, ISB, ISL, QSB, QSC, QSL, widely applied to heavy-duty trucks, dumpers, construction loaders, generator sets and commercial vehicles. Installed beside engine flywheel gear ring, it continuously captures crankshaft rotation speed and position signals, and transmits stable AC signals to ECU. The control unit relies on these data to adjust fuel injection timing, stabilize idle speed and limit engine overload. Without functional speed sensor, the engine will face hard start, power loss, unstable rotation speed and system fault codes.
