How to delete knock sensor VG30DETT Z32 300ZX

A question I see quite regularly is where is my knock/detonation sensor located & what do I do if I get a code 34 from my ecu.

The answer is quite easy you can buy a new knock sensor and relocate it for easy access in the future or the easiest and cheapest option is to bypass it.

The reason for this is unless you have your motor out or want to pull it out the knock sensor is basically impossible to get at. As shown in the picture 1 below it is located under the plenum.

First step locate your knock sensor plug as shown in Picture 2 it is located close to the firewall and roughly the centre of the engine bay the wiring will go down the back of the plenum & unplug the sensor.

Second step You will need a 1M Ohm resistor as shown in picture 3. You can purchase a 20 pack off ebay for around $2 and will probably be able to get one from an Auto shop for under $5. You will need to bend the ends to the required shape & plug it into the ecu side of the plug not the side that goes back to the plug as shown in picture 4.

Third step start up your car and you should no longer have an issue.

I hear a lot of people ask is it reliable and does it work. Yes I have done this on a drift car that is pushed to its limits every time it is driven & never had an issue with it being bypassed.

The Nissan 300zx is not known for its good turning circle or massive amounts of lock.

I managed to get some pretty decent lock out of our silver T Top drift car with very basic mods which would of cost less then $100

Will be trying a few more ideas with our slicktop drift car to see how much Lock I can get out of it without using custom knuckles etc.
