Application 

8973061131 (interchange 8-97306113-1) is a magnetic pulse-type crankshaft position (CKP) / engine speed sensor for Isuzu diesel engines. It generates an AC voltage signal as the notched flywheel teeth pass its ferrite core, allowing the ECM to determine crankshaft angular

position and engine speed for common-rail fuel injection timing, injection quantity, and EGR control. Without a valid CKP signal, the engine cannot start because the ECM cannot calculate injection sequence or piston position. The signal also drives the tachometer on many applications.

• Compatible engines: Isuzu 4HK1, 6HK1, 6WG1, 6UZ1, 6WG1.
• Compatible model: Hitachi ZX-series excavators ZX200-3, ZX240-3, ZX350H-3, ZX470H-3, ZX850-3
• Compatible model: Case CX-series excavators CX330 CX460 CX210B CX240B CX290B CX300B CX350B CX370B CX470B CX700B
• Compatible model: Sumitomo SH-series excavators SH210-5 SH240-5 SH300-5 SH350-5 SH380-5 SH460-5 SH480-5 SH700-5

Cross-reference numbers include CASE 87336454, DENSO 029600-1290, JCB 716/30301.

Fault Code Diagnostic

The ECM monitors the CKP signal for circuit continuity, signal presence, and correlation with the camshaft position (CMP) sensor.

• P0335 CKP Sensor Circuit Malfunction ECM cranks the engine > 4 seconds without a CKP pulse, or the pulse count per revolution is outside the expected window; no-start condition
• P0336 CKP Sensor Circuit Range/Performance Signal is present but the pulse pattern or count is incorrect—ECM detects the CKP reads the “wrong number of ribs per revolution”; can be caused by a damaged flywheel tooth, excessive air gap, or contaminated sensor tip
• P0016 CKP–CMP Correlation CKP and CMP signals do not align correctly; can indicate a biased CKP signal or a jumped timing chain
• P0340 or P0341 CMP Sensor Circuit / Performance Companion codes—the CMP signal may substitute for the CKP on a running engine, but a CKP fault can set CMP-related codes as secondary symptom
