Knock sensor With Wiring Harness For 95-02 Nissan Altima Maxima Xterra Infiniti

Knock Sensor With Wiring Harness for Nissan and Infiniti

This knock sensor with wiring harness detects engine detonation and sends the signal your engine computer needs to adjust timing, and it cross-references the listed OEM numbers for 95-02 Nissan Altima, Maxima, and Xterra along with Infiniti applications.

Overview

This knock sensor with wiring harness is a direct-fit replacement for worn or failed knock sensors on 1995-2002 Nissan and Infiniti vehicles. The sensor monitors engine vibration and reports detonation to the ECU so timing can be corrected before damage occurs. It suits DIY mechanics and shops servicing Altima, Maxima, Xterra, and Infiniti models from this era.

Good To Know

Q: Will this sensor clear my knock sensor code? A: It replaces the sensor and harness circuit, so the code should clear once the fault is repaired and the ECU is reset. Confirm the code points to the sensor circuit before ordering.

Q: Do I need to replace the harness along with the sensor? A: On these models the harness often fails alongside the sensor, so this combined unit saves a second repair. Inspect the old wiring for cracks or oil contamination.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
