Motorad Knock Sensor for GM V8 Applications

The Motorad 1KS1001 ignition knock sensor is built to deliver accurate engine knock detection so the ECM can adjust ignition timing based on real engine conditions. It uses a precision piezoceramic element with tight manufacturing tolerances for consistent signal response and durability.

Compatible With Chevrolet Silverado 1500, Chevrolet Tahoe, GMC Sierra 1500, and other GM truck and SUV applications listed below, this sensor supports reliable knock control across a wide range of 1983-2007 vehicles.

Key Features

  • Precision piezoceramic sensing element for accurate knock frequency response
  • Designed to provide the ECM with dependable engine condition input
  • Built to meet or exceed OEM specifications
  • Manufactured in ISO TS16949 facilities for controlled quality processes
  • Threaded end diameter: 10.0
  • Motorad part number 1KS1001 for direct catalog lookup

Detailed Description

The Motorad 1KS1001 knock sensor is engineered for GM engines that rely on precise detonation monitoring to maintain proper ignition timing. By detecting engine knock frequencies and sending that information to the ECM, the sensor helps the engine management system respond quickly to changing combustion conditions. This is a direct-fit style emission control sensor for many Chevrolet, GMC, Cadillac, Buick, Pontiac, Hummer, Isuzu, and Dodge applications. This part cross-references select OE-style numbers such as 213362 and 12589867 for the same application.

Common search phrases for this part include knock sensor for 2000-2006 Chevrolet Tahoe, knock sensor for 1999-2006 GMC Sierra 1500, and ignition knock sensor for 2002-2006 Cadillac Escalade. The Motorad 1KS1001 is also listed for Chevrolet Silverado 1500, GMC Yukon, and Chevrolet Corvette applications shown in the fitment data.

What It Helps Address

  • Check engine light related to knock sensor circuit faults
  • Audible spark knock or detonation under load
  • Incorrect ignition timing caused by poor knock signal input
  • Reduced engine performance from ECM timing correction issues
  • Driveability concerns tied to inaccurate combustion feedback

Installation Notes and Tips

Verify the threaded end diameter of 10.0 before installation and match the connector style to the vehicle harness. Fitment includes specific notes for some 2007 Silverado and Sierra HD Classic models with 1 wires, so confirm the exact engine and connector configuration before ordering. The sensor location is not listed in the fitment data, so use the vehicle service information for the correct mounting point and torque specification.
