Product Details

Delphi SS12440 is built for vehicles that depend on consistent crankshaft position input to manage ignition timing and engine operation. Delphi validates its sensors using OE development methods and calibrates them to OE standards, helping maintain accurate crankshaft signal output and reducing repeat repairs. This part cross-references Standard Ignition PC176 for the same application.

Compatible with 1999-2004 Jeep Grand Cherokee and 1997-2002 Jeep Wrangler applications, this Delphi crankshaft position sensor supports direct replacement service on select Jeep platforms. If you are searching for a Jeep Grand Cherokee crankshaft position sensor or a Jeep Wrangler crankshaft position sensor, SS12440 is the OE-style replacement to compare against your original unit.

What It Helps Resolve

  • Crankshaft signal loss or intermittent engine speed input
  • Hard starting caused by incorrect crankshaft position data
  • Stalling or rough running related to timing signal errors
  • Check engine light conditions tied to crankshaft sensor faults
  • Ignition timing issues on Jeep Grand Cherokee and Jeep Wrangler models

Installation Notes

Verify connector shape, terminal count, and harness length against the original sensor before installation. The SS12440 uses a rectangle connector, 3 terminals, and a male connector/terminal configuration. Confirm the mounting location and wiring routing on the vehicle, and follow the included instruction sheet during replacement. For best results, inspect the connector and harness for corrosion, damaged pins, or heat-related wear before installing the new sensor.

Quality Assurance

Delphi backs this sensor with OE-focused development and validation practices. Each unit is tested and calibrated to OE standards to support accurate readings and consistent engine management performance.
