Standard Ignition PC123 Engine Crankshaft Position Sensor

Engine Crankshaft Position Sensor for GM Applications

Standard Ignition PC123 is an engine crankshaft position sensor built for accurate crankshaft signal tracking in a wide range of Chevrolet, GMC, Cadillac, Oldsmobile, and Isuzu applications. It uses sealed electronics and a compact under-hood housing to support reliable operation in demanding engine bay conditions.

Key Features

• Attachment method: bolt-on for direct mounting
• 3-terminal blade connection with female connector and male terminals
• Integrated A/D conversion and digital signal processing for precise signal output
• Dynamically adaptive switch point for improved timing accuracy
• Shielded circuitry helps protect against stray electromagnetic fields and power spikes
• Rare earth magnet and surface-mount electronics in a sealed housing

Detailed Description

Standard Ignition PC123 is engineered to monitor crankshaft position and deliver a stable digital signal to the engine management system. The sensor’s custom magnetic circuit calibration helps maintain timing accuracy between the target wheel and sensor output, while the sealed construction supports dependable service in under-the-hood environments. This part cross-references Delphi SS10125 and Dorman - OE Solutions 917-755 for the same application. Common search terms include crankshaft position sensor for 1996-2007 Chevrolet Express 1500, GMC Savana 1500 crank sensor replacement, and PC123 crank sensor for Silverado, Sierra, Tahoe, and Yukon applications.

What It Helps Solve

• Crankshaft position signal loss
• Intermittent no-start or hard-start conditions
• Engine misfire or rough running caused by inaccurate timing input
• Stalling related to inconsistent crank signal data
• Check engine light concerns tied to crank sensor faults

Installation Notes and Tips

Verify connector style, terminal count, and mounting style before installation. PC123 uses a bolt-on attachment with a 3-pin blade-style connection, so matching the original sensor configuration is important for proper fitment. Confirm vehicle application by year, make, and model, especially on 1992-2007 Chevrolet, GMC, Cadillac, Oldsmobile, and Isuzu platforms such as Chevrolet Silverado, GMC Sierra, and Chevrolet Tahoe.

Quality Assurance

Standard Ignition builds this sensor with sealed electronics, advanced signal processing, and protection against electrical interference to support consistent operation in automotive service.
