just wondering if it'll work.
the plug that actually plugs into the knock sensor in the 4th gen is different from the 3.5 knock sensor, but the harness both are similar to plug into the main harness.
both knock sensors look a little different.
do you guys think the 4th gen sensor will work just like the 3.5 one?
thanx guys.

Think it should. I use VQ35 ks on the 4th gen harnest.

 

I've been running the 4th gen knock sensor with no problems. I've had it like this for 5 months now.

 

I have no basis on this statement, but it is in the back of my head somewhere I can swear I read it from another post on here .... but ...

IIRC, the 3.5 knock sensor listens to different sound frequencies or has different tolerance levels of vibrations. I don't remember the exact wording.

I would look at the FSM and see what voltages they report, see if they overlap, and make a decision based on that.

I am assuming you are using 3.0 ECU. If you have using 3.5 ECU then this is a no-brainer.

 

Perhaps resistance?

 

'97 FSM:


'02 FSM:


'97 FSM shows a reference value for the knock sensor, '02 doesn't:

 

Two notes:

1. A33 3.0's and 3.5's use the same knock sensor.

2. Reference voltages at the ECU knock sensor pin is 2.0-3.0V for the A32, ~2.5V for the A33, and ~2.5V for the A33B.

 

ok cool. so i guess there wont be any problem. thanx for all the help guys. =) you guys rock!

 

EDIT: didn't notice you had A33 there, I geuss you can replace 3.5 w/a33 and so on......

Also, the 3.5 ks is made of a different composite plastic, it looks cooler and I think down the road we will not see problems with the 3.5 sensors cracking and what not like the 3.0 ones. Upgrade for 4th gen's, though I imagine the 3.5 sensor & harness runs for a good chuink of change.

 

well i already did have the 3.5 knock sensor but i changed it to my 4th gen knock sensor because it is still practically new, just in case the 3.5 came with a bad knock sensor.

 

either one will work
