Welcome to our dedicated category for GM Genuine Parts Cam Sensors, where you'll find top-tier OEM components engineered specifically for General Motors vehicles. These sensors, including the renowned 19420911 Camshaft Position Sensor, deliver precise monitoring of camshaft position to optimize engine timing, fuel efficiency, and ignition, essential for restoring your vehicle's peak performance after wear or failure.
Understanding Camshaft Position Sensors
Camshaft position sensors are critical electronic components in modern engines, relaying real-time data on the camshaft's rotational position to the engine control module (ECM). This information synchronizes valve timing with piston movement, ensuring efficient combustion. In GM vehicles, a faulty sensor can trigger misfires, rough idling, reduced power, or check engine lights, making timely replacement vital for safety and reliability.
GM Genuine Parts stands out as the official OEM supplier from General Motors, guaranteeing exact specifications, superior build quality, and plug-and-play compatibility. Unlike generic aftermarket options, these sensors use premium materials like robust housing and high-precision Hall effect or magnetic technology for accurate readings even under extreme conditions.

Key Features and What to Look For
When selecting a cam sensor, focus on these buyer essentials:
- Compatibility: Verify fitment for your GM model year and engine type, GM Genuine Parts excels here with vehicle-specific designs.
- Sensor Technology: Opt for Hall effect sensors for superior accuracy over inductive types.
- Build Quality: Corrosion-resistant connectors and sealed housings for longevity.
- Wiring Integrity: Pre-attached harnesses reduce installation errors.
- Performance Specs: Fast response times (under 1ms) for optimal timing control.
The 19420911 embodies these traits, making it ideal for popular GM applications like Chevy, GMC, and Cadillac engines.
Common Use Cases and Replacement Guide
Replace your cam sensor if you notice symptoms like stalling, poor acceleration, or P0340/P0341 codes. It's a straightforward job for most GM models: locate the sensor near the camshaft (often top-front of the engine), disconnect the battery, unplug the harness, unscrew, and install the new one with fresh O-rings if needed. Torque to spec (typically 10-15 Nm) and clear codes post-install.
For broader automotive maintenance, these sensors pair well with other components in our Replacement Parts selection. If you're servicing the full ignition system, check related options in Sensors.
Comparing GM Genuine Parts to Alternatives
While GM Genuine Parts offers OEM precision, aftermarket brands provide variety. For budget-conscious shoppers, explore A-Premium Cam Sensors or ACDelco Cam Sensors, which mimic OEM fit but at potentially lower costs. Brands like Dorman Products Cam Sensors suit high-mileage repairs. However, for guaranteed compatibility and performance in GM vehicles, stick with Genuine Parts, especially versus universal sensors that may require adapters.
