Delphi SS12173 Engine Crankshaft Position Sensor

Engine Crankshaft Position Sensor for OE-Style Signal Accuracy

Delphi SS12173 is an engine crankshaft position sensor built for vehicles that need accurate crankshaft timing input for proper engine management. It is a direct-fit style replacement for a wide range of Buick, Chevrolet, Oldsmobile, and Pontiac applications, including the Pontiac Grand Am, Chevrolet Malibu, and Oldsmobile Alero.

Key Features

• Black sensor housing with a 3-terminal male pin connector
• Oval connector shape with 1 connector and wiring harness included
• 207.5 wiring harness length for application-specific routing
• Tested and calibrated to OE standards for accurate readings
• Package contents include the engine crankshaft position sensor and instruction sheet
• Cross-reference example: Standard Ignition PC61

Detailed Description

Delphi SS12173 is an ignition sensor designed to monitor crankshaft position and send the engine control module the timing data it needs for fuel and spark control. Delphi validates its sensors using OE development and product testing methods, and each unit is calibrated to OE standards to help maintain consistent signal output. This makes SS12173 a practical replacement for vehicles such as the Pontiac Grand Am, Chevrolet Malibu, and Buick Rendezvous when the original crankshaft position sensor is failing or producing erratic readings.

This part cross-references Standard Ignition PC61 for the same application.

What It Helps Address

• Hard starting caused by an inaccurate crankshaft position signal
• Intermittent stalling related to sensor signal loss
• Misfire or rough-running conditions tied to timing input errors
• Check engine light concerns associated with crankshaft sensor faults
• Crank/no-start complaints on affected Buick, Chevrolet, Oldsmobile, and Pontiac models

Installation Notes and Tips

Verify connector style, terminal count, and harness routing before installation. The sensor uses a male oval connector with three terminals and includes a wiring harness, so confirm the original layout matches the vehicle application. Inspect the mounting area and related wiring for damage, corrosion, or oil contamination before installing the new sensor. After installation, clear diagnostic trouble codes and confirm stable engine speed data during startup and idle.

Quality Assurance

Delphi backs this crankshaft position sensor with OE-focused development, product validation, and calibration practices. The sensor is tested to OE standards to support accurate readings and reduce repeat repairs.
