Product Details

This Spectra S10400 crankshaft position sensor is used to report crankshaft position data to the engine control system, helping the vehicle manage spark timing and engine speed calculations. It is a practical replacement for vehicles such as the Chevrolet Malibu, Chevrolet Camaro, GMC Acadia, and Cadillac CTS when the original sensor is failing or producing inaccurate signals. This part cross-references Delphi SS12172 and Standard Ignition PC977 for the same application.

Common Problems It Can Help Resolve

• Hard starting or extended cranking
• Intermittent stalling or sudden engine shutdown
• Check engine light related to crankshaft position signal faults
• Rough running caused by inconsistent engine speed input
• Ignition timing errors from a weak or missing crankshaft signal

Installation Notes

Verify connector shape, terminal count, and sensor body diameter before installation. This part uses a single oval connector with 3 male blade terminals and does not include a wiring harness or mounting bracket. Confirm the vehicle’s original sensor location and compare the OE connector style before replacement.
