The CZP Knock Sensor Sub Harness is a direct replacement for the sub harness found between the main EFI harness and the knock sensor on all VQ35DE powered Nissan 350Zs and Infiniti G35s. Nissan only sells this harness as a complete assembly with the fuel injector harness as well, even though they are completely sperate circuits.

The DTC P0327 is most commonly triggered by a bad connection to the knock sensor, or a failing sensor. The harness is the most common cause, though we do sell the knock sensor itself separately here.

NOTE: G35 models manufactured before 06/03 MUST also change the knock sensor itself. The earlier design uses a different connector style, so on earlier models, you need to run both the new style sensor and the new style harness (which this is).
