Spectra S10409 Engine Camshaft Position Sensor

Engine camshaft position sensor for GM trucks

The Spectra S10409 engine camshaft position sensor helps manage ignition timing and injector synchronization by reporting camshaft position to the engine control system. It is a direct-fit replacement for a wide range of Chevrolet and GMC applications, including heavy-duty vans and pickups.

Key features

• Monitors camshaft position for accurate cylinder-firing sequence control.
• Supports ignition timing and fuel injector synchronization.
• Direct-fit replacement for selected Chevrolet and GMC applications.
• Part number S10409 for easy identification and ordering.

Detailed description

The Spectra S10409 is an engine camshaft position sensor built for vehicles that rely on precise timing input to coordinate spark and fuel delivery. In applications such as the Chevrolet Silverado 2500 HD, Chevrolet Express 3500, and GMC Sierra 2500 HD, the sensor provides the signal the engine management system uses to determine which cylinder is firing. That information is essential for stable ignition timing and proper sequencing of the coil and injector events. This part cross-references Standard Ignition PC660 for the same application.

What it helps address

• Hard starting caused by incorrect camshaft position input.
• Misfire conditions related to timing signal loss.
• Rough idle from inconsistent cylinder synchronization.
• Check engine light concerns tied to camshaft sensor faults.
• Fuel delivery timing issues in GM truck and van applications.

Installation notes and tips

Verify the connector style and engine application against the vehicle service information before installation. Confirm the sensor location and inspect the harness and terminals for damage or corrosion that could affect signal quality. Fitment includes 2006-2016 Chevrolet Express 2500, Express 3500, Silverado 2500 HD, Silverado 3500, Silverado 3500 HD, 2006-2016 GMC Savana 2500, Savana 3500, Sierra 2500 HD, Sierra 3500, 2010-2016 Chevrolet Express 4500 and GMC Savana 4500, plus 2006-2007 Chevrolet Silverado 3500 Classic and 2006-2007 GMC Sierra 3500.

Quality assurance

Spectra supplies ignition and sensor components for service replacement applications, and the S10409 is cataloged for direct-fit use across the listed GM platforms. Part number S10409 should be matched to the vehicle application before installation.
