Detailed Description

Delphi SS12127 is engineered for vehicles that rely on accurate crankshaft position input to support ignition timing and engine control. Delphi draws on more than a century of OE experience, and that knowledge is reflected in the design and construction of this replacement sensor. This part cross-references Standard Ignition PC484 for the same application.

Compatible With 2005 Chrysler 300, 2005 Dodge Magnum, 2004 Dodge Durango, and 2003-2004 Dodge Ram 1500, Ram 2500, and Ram 3500. It is a direct-fit style replacement for Chrysler 300 and Dodge Ram applications where the original sensor uses the same connector and terminal layout.

Common Issues This Sensor May Resolve

• Crankshaft signal loss that affects engine starting
• Intermittent stalling or rough running related to crank position input
• Check engine light concerns tied to crankshaft sensor faults
• Hard-start conditions caused by inaccurate engine speed data
• Ignition timing problems from a failing crankshaft position sensor

Installation Notes and Tips

Verify connector shape, terminal count, and sensor location before installation. This part does not include a wiring harness, so reuse the existing harness connection when serviceable. Compare the original sensor to the Delphi SS12127 and confirm fitment for your specific Chrysler 300, Dodge Magnum, Dodge Durango, or Ram truck application before replacement.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and application knowledge developed through long-term supplier experience with major automakers. The SS12127 is packaged with an instruction sheet to support proper installation and service.
