Detailed Description

Motorad 1KS1311 is engineered to detect knock across a wide range of engine frequencies so the ECM can adjust ignition timing based on real-time combustion conditions. This helps maintain proper engine operation in vehicles such as the 2011-2015 Chevrolet Cruze, 2012-2020 Chevrolet Sonic, 2011-2015 Chevrolet Volt, 2013-2021 Chevrolet Trax, 2013-2021 Buick Encore, and 2014-2016 Cadillac ELR. The sensor uses a high-quality piezoceramic element for consistent signal output and durability, and it is designed to meet or exceed OEM specifications. This part cross-references Standard Ignition KS394 for the same application.

What It Is Used For

• Diagnosing knock sensor fault codes
• Restoring accurate ignition timing control
• Addressing rough running caused by incorrect knock input
• Correcting reduced engine performance related to sensor signal loss
• Replacing a worn or failed detonation sensor on GM applications

Installation Notes and Tips

Verify connector shape, terminal count, and bolt-on mounting before installation. The sensor uses a female connector, 2 blade terminals, and no included harness, so inspect the vehicle-side connector for corrosion or damage before fitting. Confirm exact vehicle application by year, make, and model before ordering.
