350Z / G35 VQ35DE Knock Sensor Sub Harness

starstarstarstarstar 5/5 - (7 Reviews)
Fits models: 350Z / G35 / FX35 / FX45

Product Description

This is the Knock Sensor Sub Harness found on all Nissan 350Z and Infiniti G35 models equipped with the VQ35DE Engine. When this harness fails you will see a Check Engine Light with the code P0327.

P0327 Codes are caused by either a low output voltage seen by the ECU from the knock sensor pointing to a faulty sensor or a short or open knock sensor circuit.  
While most often this code is indicative of a faulty knock sensor sub harness, sometimes the sensors do go bad you can elect to purchase both below and save.

Z1 also sells new OEM Knock Sensors HERE and can be included for a discounted price as an option below.

NOTE: G35 models with a build production date before 06/03 MUST purchase a new style knock sensor with the harness. The original knock sensor on G35's built prior to 06/03 is different, and cannot be connected with this new style harness. The optional knock sensor below is a new-style type sensor and will allow you to use the newer style knock sensor sub harness sold here.

Fits:

  • 2003-2006 Nissan 350Z
  • 2003-2007 Infiniti G35 Coupe
  • 2003-2006 Infiniti G35 Sedan
  • 2003-2008 Infiniti FX35

This is intended for the above listed models ONLY. Fitment on FWD VQ's (Maxima, Altima, etc.) has not been confirmed.

Super happy with this item. It was cheaper than some other parts resources near me. Parts and shipping was half of what other parts places wanted to sell it to me over the counter. Plugged in perfectly w/ no issues. Took care of my p0327 code that was caused by a rodent chewing the wiring.

Worked on my 2004 G35. Ordered Monday night in Texas and received on Tues. Shipping was unbelievably fast. A pain to get to to install. Will definitely use Z1 Motorsports again and highly recommend them.

Have not installed the sub harness yet but am very impressed by Z1's speed of service/shipping. I live in Canada and ordered the item at 5pm on Wednesday, I expected it to show up the next week but to my surprise it arrived at 11AM the next day. You guys rock!

This fixed my P0327 fault code. The factory sub harness in these cars is very poor quality. Every time it was humid or raining I would get P0327 fault, and the car ran poorly.

The connector had one tab that didn't match. So I took a sharp knife and shaved off the offending tab. It was an easy fix. Then I assembled the cables and etc. My 2003 G35 has been running great since. No more error code. Thought someone might find this useful.

This knock sensor sub harness is a must if you are getting a low knock sensor input signal code. Install is tedious and takes about 2 hours. If you have a loss of engine power and have the previous mentioned cel code, this is your fix. Thanks Z1!
