Detailed Description

The Delphi SS12004 is an engine crankshaft position sensor engineered for vehicles that rely on precise crankshaft position feedback to manage spark timing and engine operation. It uses a rectangular connector, female connector gender, and male blade terminals for a straightforward OE-style electrical interface. This sensor is a strong match for drivers searching for a crankshaft position sensor for 2002-2010 Dodge Ram 1500, 2000-2009 Dodge Durango, or 1999-2009 Jeep Grand Cherokee service.

This part cross-references Standard Ignition PC284 for the same application. It also cross-references Walker Products 235-1136 for the same application.

What It Helps Address

• Crankshaft signal loss or intermittent engine speed readings
• Hard starting caused by incorrect crank position input
• Stalling related to faulty crankshaft sensor data
• Misfire or timing issues tied to inaccurate ignition reference signals
• Check engine light conditions associated with crank sensor faults

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle application before installation. The SS12004 uses a 3-terminal blade connection and does not include a wiring harness, so inspect the existing harness and connector for wear, corrosion, or damage before fitting the new sensor. Confirm the sensor location on the engine and follow the vehicle service procedure for removal and installation.

Quality Assurance

Delphi builds this sensor with OE-focused engineering informed by more than a century of original equipment experience and supplier relationships with leading automakers. That background supports consistent fitment and electrical performance across the listed applications, including Ram 1500, Dodge Dakota, and Jeep Grand Cherokee models.
