Global Parts 1815046 Ignition Knock (Detonation) Sensor

Ignition Knock Sensor for GM Applications

Global Parts 1815046 is an ignition knock sensor for vehicles that use a pin-style, oval connector design. It monitors engine vibration patterns at the block, cylinder head, or intake manifold so the engine control system can respond to abnormal pre-ignition or detonation. This Global Parts knock sensor is a direct-fit service part for a wide range of Chevrolet, GMC, Cadillac, Buick, Pontiac, and Hummer applications.

Key Features

• Part number: 1815046
• Ignition knock (detonation) sensor for emission control and engine management systems
• Pin terminal type with 2 terminals
• 1 male oval connector with female terminals
• Mounting hardware not included
• Fits many GM trucks, SUVs, vans, and performance models from 1999-2007

Detailed Description

Global Parts 1815046 is built for vehicles that rely on a knock sensor to detect abnormal combustion-related vibration and send that signal to the engine control module. The sensor location is typically on the engine block, cylinder head, or intake manifold, where it can read the vibration changes associated with detonation. This makes it a practical replacement for GM platforms such as the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe, GMC Yukon, Cadillac CTS, and Pontiac GTO. This part cross-references Dorman OE Solutions 926-084 for the same application.

Installation Notes

Verify connector shape, terminal count, and mounting location before installation. This sensor uses a single oval connector with pin-style terminals, so matching the harness connection is important for proper fitment. Inspect the surrounding wiring and pigtail condition during service, especially on Chevrolet Silverado 1500, GMC Sierra 1500, and Tahoe applications where heat and vibration can affect the circuit.

Quality Assurance

Global Parts 1815046 is a service replacement knock sensor engineered for the listed GM applications and interchange references. Confirm vehicle year, make, model, and engine configuration against the fitment data before ordering.
