The Delphi SS12445 engine crankshaft position sensor is built for accurate engine speed and crank position signal input on select Jeep applications. It is a direct-fit sensor for 2018-2021 Jeep Wrangler and 2019-2021 Jeep Cherokee, with OE-style connector and terminal design for straightforward replacement.

Key Features

• Engine crankshaft position sensor for ignition and engine management systems
• Black housing with oval, 1-connector design
• 3-terminal, male connector and male terminal configuration
• 1 mounting hole for OE-style installation
• Package contents include the sensor and instruction sheet
• Delphi SS12445 is tested and calibrated to OE standards for accurate readings

Detailed Description

Delphi SS12445 is an OE-style crankshaft position sensor engineered for vehicles that rely on precise crankshaft signal data to manage ignition timing and engine operation. Delphi validates its sensors through OE development and product testing methods, helping ensure consistent signal output and reduced comeback risk. This part cross-references Standard Ignition PC1224 for the same application. It is a strong replacement choice for Jeep Wrangler and Jeep Cherokee owners looking for a direct-fit engine crankshaft position sensor with the correct connector shape, terminal count, and mounting layout.

What This Sensor Helps Resolve

• Crankshaft signal loss that can trigger a no-start condition
• Intermittent stalling caused by inaccurate engine speed input
• Rough running related to inconsistent crank position data
• Check engine light concerns tied to crankshaft sensor faults
• Hard starting after a failed or weakened crankshaft position sensor

Installation Notes and Tips

Verify connector shape, terminal count, and mounting point before installation. The Delphi SS12445 uses a single oval connector with a 3-pin male terminal layout and does not include a wiring harness or mounting bracket. Confirm the vehicle application against the listed fitment for 2018-2021 Jeep Wrangler and 2019-2021 Jeep Cherokee before replacement.

Quality Assurance

Delphi sensors are developed and validated to OE standards and calibrated for accurate readings. That OE-focused testing helps support reliable signal performance in the ignition system and reduces the chance of repeat repairs.
