| High Light | Magnetic Pulse-Type Crankshaft Position Sensor ，Hall Effect Signal CKP Sensor ，3-Pin Connector Engine Position Sensor | ||
The Crankshaft Position Sensor (CKP Sensor) with OEM numbers 8973061131 / 8-97306113-1 (DENSO cross-reference 029600-1290) is a verified direct-fit replacement for ISUZU 4HK1 / 6HK1 series diesel engines. This sensor is one of the most critical signal inputs to the Engine Control Module (ECU), widely used in ISUZU 700P / NPR / NQR / NKR series trucks and Hitachi ZAX200-3 / ZAX240-3 heavy excavators.
The Crankshaft Position Sensor (CKP) is located on the flywheel housing at the left rear corner of the engine and is a magnetic pulse-type sensor. The flywheel periphery has 45 projections equally spaced every 7.5°, with one space (equal to 3 projections) serving as a Top Dead Center (TDC) reference signal. The sensor detects the pulse signals generated as the projections pass by. The ECU calculates engine speed and the exact crankshaft angular position based on these 45 pulses and the TDC reference signal. The ECU uses these signals to precisely control fuel injection timing, fuel quantity, and ignition (for gasoline engines), ensuring stable engine operation, optimal power output, and fuel efficiency.
