Detailed Product Information

NTK ID0050 is a replacement knock sensor used to detect engine detonation so the engine control system can adjust ignition timing. This matters on vehicles such as the Chevrolet Malibu, GMC Terrain, and Cadillac XT5, where accurate knock feedback helps maintain smooth operation and proper engine management. This part cross-references Standard Ignition KS374 for the same application.

NTK’s technical sensor line is supported by more than 80 years of automotive experience through the NGK family of products. The ID0050 is part of that OE-focused coverage for vehicles across the 2009-2025 model years.

What It Helps Address

• Knock sensor fault codes
• Audible spark knock or pinging under load
• Reduced engine performance from incorrect timing control
• Check engine light related to detonation sensing
• Rough running caused by inaccurate knock signal input

Installation Notes and Tips

Verify connector shape, terminal count, and mounting location before installation. This sensor uses a female connector with male blade terminals, so matching the OE-style plug is important for proper fit. Confirm vehicle-specific application details for Chevrolet Equinox, Buick Enclave, and GMC Acadia before service.

For best results, inspect the harness and mounting surface during replacement and clear any stored diagnostic trouble codes after installation.

Quality Assurance

NTK sensors are tested under thermal shock, vibration, and OBD verification to support OE-level performance. The ID0050 is manufactured to meet or exceed OE specifications for the listed applications.
