Standard Ignition PC975 Engine Camshaft Position Sensor

Engine Camshaft Position Sensor for GM Applications

Standard Ignition PC975 is an engine camshaft position sensor built for accurate cam timing signal input across a wide range of Chevrolet, GMC, and Cadillac applications. It uses integrated analog-to-digital conversion and digital signal processing to improve signal consistency in demanding engine management systems.

Fits 2014-2025 Chevrolet Silverado 1500, N/A; Fits 2015-2025 Chevrolet Tahoe, N/A; Fits 2015-2024 Cadillac Escalade, N/A. This part cross-references Delphi SS11936 for the same application.

Key Features

• Engine camshaft position sensor for ignition and engine management systems
• Integrated A/D converter and digital signal processing for refined output control
• Dynamically adaptive switch points to improve timing accuracy
• Advanced circuitry helps protect against stray electromagnetic fields and power spikes
• Custom magnetic circuit programming and performance testing for target wheel synchronization
• Female oval connector with plug-in design
• 3-pin male terminals
• No mounting bracket and no wire lead included

Detailed Description

Standard Ignition PC975 is engineered to deliver a stable camshaft position signal for vehicles that rely on precise engine timing data. The sensor’s internal processing helps maintain accurate timing between the target wheel and sensor output, while environmental, endurance, and end-of-line testing helps verify timing, pulse width, and signal amplitude consistency. Standard Ignition PC975 is a direct-fit style replacement for many GM platforms, including Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Camaro, and Cadillac CTS applications.

Additional interchange references include Spectra Premium S10349 and Walker Products 235-1881.

What It Helps Address

• Camshaft position sensor fault codes
• Intermittent engine stalling or rough running
• Hard starting caused by inaccurate cam signal input
• Misfire concerns related to timing signal errors
• Check engine light conditions tied to cam sensor performance

Installation Notes and Tips

Verify connector style, terminal count, and engine application before installation. This sensor uses a female oval connector with a 3-pin male terminal layout and a plug-in connection. Some applications may require programming for installation, including certain 2019 GMC Sierra 1500 Limited listings. Confirm the exact vehicle year and model before ordering, especially on Silverado, Sierra, Tahoe, Yukon, Escalade, Camaro, Corvette, and CTS applications.

Quality Assurance

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