Product Description
Need to fix a P0325 or P0328 on your Nissan Titan? The Z1 Off-Road Knock sensor sub-harness is the most affordable and common solution for this repair.
Installed below the intake manifold, the knock sensor sub-harness connects the engine harness to the knock sensor. Repeated heat cycles cause wire insulation and connectors to become brittle, breaking down and resulting in poor or no connection to the knock sensor. Additionally, vehicles that are stored for extended periods of time may find the wiring is often damaged by small animals that live under the hood.
The Z1 Knock Sensor Sub Harness features upgraded single core shielded wire which is superior to the original equipment. Featuring a stranded signal core with insulated and spiral wound grounded shield wire it is the same material Z1 has been building knock sensor sub harnesses with since 2011. Harnesses feature OEM connector bodies and terminals for the best quality available. You can trust a Z1 harness as they have been used in applications ranging from daily driver to complete competition engine builds for over a decade.
Commonly associated diagnostic codes:
- P0325 - Knock Sensor Circuit Malfunction - most commonly caused by either a low output voltage from the knock sensor or from a faulty and corroded sub-harness. Sometimes the sensors do fail but the most common issue is the sub-harness. Replacement OEM knock sensors can be found HERE.
- P0327 - Knock Sensor Circuit Low Input - Most commonly caused by a short in the harness between the sensor and the ECU. What's the most likely solution to this problem? Replace the sub-harness.
- P0328 - Knock Sensor Circuit High Input - Most commonly caused by a corroded or open circuit between the sensor and ECM. Again the most common solution is a replacement sub-harness.

The harness appeared and worked as it should. It was odd that it came in no product packaging, but that did not affect its functionality. The knock sensor connectors were not marked as to bank. One was slightly longer, and the bank 2 sensor sits slightly more after on the engine, but they could easily work both directions. To ensure they were correct before I reinstalled the manifold, I referred to the factory schematics and tested continuity back to the ECM connector.

First time using these guys and all I can say is excellent. They answered any questions I had about the product, never had any issues with any part of it. Shipping was right on time. I will be using them in the future.
