The sensor communicates crankshaft speed and position information to the ECM, which is critical for consistent starting, stable idle, and correct ignition timing. This part cross-references Standard Ignition PC552 for the same application.

Compatible With 2006-2017 Chevrolet, GMC, Cadillac, Buick, Pontiac, Hummer, Saab, and related GM-platform vehicles, including long-tail applications such as a crankshaft position sensor for Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, and Chevrolet Express 3500. The part number 1812447 is also commonly searched for GM crankshaft position sensor replacement needs.

What It Helps Address

• Crankshaft position sensor fault codes
• Hard starting or no-start conditions tied to crank signal loss
• Rough idle or intermittent stalling
• Incorrect ignition timing or misfire-related drivability concerns
• ECM input errors affecting fuel and engine management operation

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. This sensor uses a blade terminal layout with an oval female connector and male terminals, so matching the OE connector is important for proper fitment. Confirm the exact model year and engine configuration against the vehicle listing before replacing the original sensor.

For best results, inspect the harness connector and surrounding wiring for corrosion, bent terminals, or heat damage before installing the new sensor. Clear any stored diagnostic trouble codes after replacement and verify that the engine starts and runs normally.

Quality Assurance

Global Parts engine management sensors are built to provide accurate ECM input and are manufactured as direct replacement components that meet OE specifications.
