Standard Ignition PC964 Engine Crankshaft Position Sensor

Engine Crankshaft Position Sensor for GM Applications

Standard Ignition PC964 is an engine crankshaft position sensor built for direct replacement service on a wide range of Chevrolet, GMC, and Cadillac vehicles. It uses integrated analog-to-digital conversion and digital signal processing to improve signal accuracy, timing consistency, and overall engine management performance.

Compatible With Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, and other GM models listed below, this PC964 sensor is engineered for stable crank signal output in demanding ignition and engine control systems.

Key Features

• Engine crankshaft position sensor for ignition and engine timing input
• Integrated A/D converter and digital signal processing
• Dynamically adaptive switch points for improved signal accuracy
• Advanced circuitry helps protect against stray electromagnetic fields and power spikes
• Custom magnetic circuit programming for calibrated sensor output
• Performance tested for timing, pulse width, and signal amplitude consistency
• Female oval plug-in connector with 3 male blade terminals
• No mounting bracket and no wire lead included

Detailed Description

Standard Ignition PC964 is built to deliver a precise crankshaft position signal to the engine control system. The sensor’s internal processing helps refine output timing between the target wheel and sensor response, supporting accurate ignition and fuel control on GM trucks, SUVs, and performance cars. This part cross-references Four Seasons 73488 for the same application.

Fits 2014-2021 Chevrolet Silverado 1500, N/A; fits 2020-2024 Chevrolet Silverado 2500 HD, N/A; fits 2015-2020 Cadillac Escalade, N/A; fits 2014-2021 GMC Sierra 1500, N/A; fits 2014-2023 Chevrolet Corvette, N/A; fits 2016-2021 Chevrolet Camaro, N/A.

What It Helps Fix

• Crankshaft position sensor fault codes
• Hard starting or extended crank conditions
• Intermittent stalling or engine shutdown
• Rough running caused by inaccurate crank signal input
• Misfire or timing-related drivability concerns

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. The PC964 uses a female oval plug-in connector with 3 male blade terminals, so the harness connection should match exactly. Inspect the target wheel, wiring, and connector terminals for damage or contamination before replacing the sensor.

For best results, clear diagnostic trouble codes after installation and confirm proper crank signal operation during a road test or scan tool verification.

Quality Assurance

Standard Ignition subjects this sensor to environmental, endurance, and end-of-line testing for timing, pulse width, and signal amplitude to support consistent operation. The design also includes circuitry protection against electromagnetic interference and power spikes.
