Detailed Product Overview

The Motorad 1CS127 camshaft position sensor monitors camshaft position so the engine control module can manage ignition timing and fuel delivery with the correct signal input. This helps maintain proper engine operation across many GM truck, SUV, and performance applications, including Chevrolet Express 2500, GMC Savana 3500, Cadillac CTS, Chevrolet Camaro, and Pontiac G8. The 1CS127 is also cross-referenced to common OE and aftermarket numbers for the same application, including 917744 and 2131586.

Use this sensor when servicing GM vehicles that rely on precise camshaft position feedback for smooth starting, stable idle, and accurate engine synchronization. The Motorad 1CS127 is a practical replacement for many 2004-2020 Chevrolet and GMC platforms, as well as select Cadillac, Buick, Pontiac, Saab, and Hummer models.

What This Sensor Helps Address

• Hard starting caused by an inaccurate camshaft signal
• Rough idle or inconsistent engine timing feedback
• Check engine light concerns related to camshaft position sensor faults
• Stalling or hesitation tied to poor engine synchronization
• Driveability issues on GM trucks, SUVs, and performance cars

Installation Notes and Fitment Tips

Verify connector shape, terminal count, and engine application before installation. This sensor uses a female oblong connector with 3 blade terminals and does not include a wiring harness or mounting bracket. Confirm the vehicle’s original sensor style matches the Motorad 1CS127 before replacement.
