NTK ID0050 Ignition Knock (Detonation) Sensor

The NTK ID0050 is a premium ignition knock (detonation) sensor engineered to protect your engine from the damaging effects of detonation. This sensor continuously monitors engine vibrations and relays data to the ECM to dynamically adjust ignition timing, helping prevent engine knock before serious damage occurs.

At the heart of the ID0050 is advanced piezo ceramic technology. A piezoelectric crystal generates a varying voltage signal based on engine vibration intensity, which the ECM uses to retard ignition timing as needed. The sensor is internally sealed to block moisture intrusion, and the shielded wiring harness eliminates electrical interference for a clean, accurate signal.

Key Features:

• Detects engine knock caused by detonation and signals the ECM to adjust ignition timing
• Advanced piezo ceramic technology for accurate vibration sensing and increased durability
• Internally sealed design prevents moisture intrusion
• Reinforced and extra-strength components reduce the risk of part failure and corrosion
• Shielded harness prevents electrical interference
• Harness length and wire gauge match original equipment for a seamless installation
• Mounting threads match OE specifications for a straightforward, worry-free fit
• Manufactured to meet or exceed OE fit, form, and function
• Subjected to rigorous testing including thermal shock, vibration, and OBD verification

NTK is the only OE supplier offering a full line of technical sensors in the aftermarket for both import and domestic vehicles. Backed by over 80 years of NGK automotive expertise, NTK sensors are held to the same stringent standards as original equipment — making the ID0050 a reliable, direct-replacement solution for restoring proper ignition timing and protecting engine longevity.

Common reasons for knock sensor replacement include an illuminated check engine light, engine hesitation, reduced fuel economy, or a failed emissions test.
