Nissan Parts & Accessories Ignition Knock (Detonation) Sensor

Nissan Genuine OEM Ignition Knock (Detonation) Sensors

When it comes to protecting your Nissan's engine from the damaging effects of pre-ignition and detonation, there is no substitute for a factory-engineered solution. Nissan Parts & Accessories offers genuine OEM Ignition Knock (Detonation) Sensors built to the exact tolerances your vehicle's engine management system was designed around — no guesswork, no compromises.

What Does the Knock Sensor Do?

The Ignition Knock (Detonation) Sensor monitors vibrations caused by engine knock or detonation to alter the ignition timing and prevent detonation. Inside the sensor, a piezoelectric crystal generates a varying voltage based upon engine vibration intensity to delay ignition timing, helping prevent severe and costly engine damage. This constant feedback loop between the sensor and the ECM is what keeps your Nissan running smoothly, efficiently, and safely under a wide variety of driving conditions.

Common reasons for replacement include check engine light illumination, engine hesitation, poor fuel economy, or a failed emissions test. Left unaddressed, a failed knock sensor can allow detonation to persist unchecked, accelerating wear on pistons, rings, and bearings.

Why Choose Nissan Genuine OEM?

Nissan's genuine OEM knock sensors are manufactured to match the factory part in every dimension — connector shape, thread pitch, wire harness length, and sensitivity range. All genuine OEM parts guarantee a perfect fit for your Nissan vehicle, ensuring the sensor performs exactly as intended from the factory. This is a critical advantage over generic aftermarket alternatives, where even small deviations in sensitivity calibration can cause the ECM to over-retard or under-retard timing, robbing your engine of power or leaving it vulnerable to knock damage.

Nissan's OEM knock sensors have covered an extensive range of popular models and engine families over the years. Genuine OEM part numbers such as 22060-30P00 have served applications spanning 1990–2004 Nissan vehicles, while part numbers like 22060-2Y000 and B2060-7B000 have been applied to platforms including the Maxima, Pathfinder, and Altima 3.5L. Whether you drive a classic pickup, a V6-powered SUV, or a performance-oriented sports car, Nissan's OEM program has the correct sensor for your specific build.

The Right Part for Your Nissan

Because knock sensor design is tightly coupled to a specific engine's resonant frequency and block geometry, using the genuine Nissan part eliminates the risk of signal mismatch. The sensor threads directly into the engine block, and OEM-matched connector terminals ensure a secure, corrosion-resistant connection with the factory wiring harness — no adapter pigtails or modification required.
