Spectra S10569 Crankshaft Position Sensor

The Spectra S10569 is a standard replacement engine crankshaft position sensor for vehicles that rely on accurate ignition timing and engine speed input. It monitors crankshaft position to help the engine control system manage spark timing and RPM feedback, making it a direct fit for select Chevrolet, GMC, and Cadillac applications.

Key Features

• Engine crankshaft position sensor for ignition timing and RPM signal input
• Standard replacement design for OE-style service
• 12.0-volt electrical specification
• Female oval connector with 3 male terminals
• 1 connector, 1 mounting hole, and included mounting bracket
• Black housing
• No wiring harness included

Detailed Description

Built for direct service replacement, the Spectra S10569 crankshaft position sensor supports the engine management system by tracking crankshaft movement and sending the signal used for ignition timing and engine speed calculation. This helps eliminate the need for manual distributor timing on applications that use electronic engine control. The connector layout, terminal count, and mounting style are specified for a clean replacement on supported vehicles, including 2019-2024 Chevrolet Silverado 1500, 2019-2024 GMC Sierra 1500, and 2021-2023 Cadillac Escalade models. The Spectra S10569 is also listed for 2021-2023 Chevrolet Tahoe and 2021-2023 GMC Yukon and Yukon XL applications.

This part cross-references Standard Ignition PC1182 for the same application.

What It Helps Fix

• Crankshaft signal loss that can trigger hard starting
• Erratic ignition timing or unstable spark control
• Incorrect engine RPM readings at the control module
• Intermittent stalling related to crank signal interruption
• Check engine light conditions tied to crankshaft position sensor faults

Installation Notes

Verify connector shape, terminal count, and mounting point before installation. The S10569 uses a female oval connector with three male terminals and includes a mounting bracket, so confirm the sensor location and bracket alignment against the original part. Inspect the connector terminals and wiring for corrosion or damage before fitting the new sensor. For best results, clear diagnostic trouble codes after installation and confirm stable engine speed data during startup and idle.

Quality Assurance

Spectra supplies this crankshaft position sensor as a standard replacement part for supported GM and Cadillac applications. It is engineered to match the listed electrical and mounting specifications for service use on vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade.
