bigsyke Posted December 17, 2009 Share Posted December 17, 2009 Does anybody know (if it has one) which ECU pin/color the knock sensor is on? (1987 pathy vg30i v6 4dr) Thank you much! The vg30e is pin 27, white. However Im not sure if theyre the same. Link to comment Share on other sites More sharing options...
MY1PATH Posted December 17, 2009 Share Posted December 17, 2009 Its in the cyl valley underneath the intake manifold. Kind of a PITA to get to if you need to change it. Link to comment Share on other sites More sharing options...
bigsyke Posted December 17, 2009 Author Share Posted December 17, 2009 thats why im going to bypass it at the ECM harness. Link to comment Share on other sites More sharing options...
bigsyke Posted January 8, 2010 Author Share Posted January 8, 2010 (edited) I currently have the FSM for the VG30E pathys however I have the VG30I. Im trying to find the Knock sensor wire on the ECU, and it says its pin 27 for the VG30E. Is it the same for the VG30I? Thank you!

nismothunder Posted January 8, 2010 Share Posted January 8, 2010 (edited) There a right up on hear for checking codes,I think its in the garage section and yes I believe it is the same... Where are you in mn...? Edited January 12, 2010 by RedPath88 Merged Thread Link to comment Share on other sites More sharing options...
RedPath88 Posted January 8, 2010 Share Posted January 8, 2010 (edited) Pin 27 on a 1989 VG30i (TBI) ESM is not the Knock Sensor, instead it is the Main Relay. As far as I know the TBI versions of the VG30's do not have a Knock Sensor. Can you fill in your profile, so we can better help you in the future?

pathfinderfisherman Posted January 12, 2010 Share Posted January 12, 2010 (edited) thats why im going to bypass it at the ECM harness. red path 88 can probably help tell u what wires colors are i think he might have an fsm for the older ones i think i might like a copy myself... these pics are how i did mine...to test and make sure the resistor will work and the other bridged in dont get scared the pics aare a 300 z i think but the principle is the same let your ecm think the sensor is good u can see the wires go down under the mani pull that plug and see if sticking each end of the resistor gives you a 55 code Edited January 12, 2010 by pathfinderfisherman Link to comment Share on other sites More sharing options...
Precise1 Posted January 12, 2010 Share Posted January 12, 2010 The other thing you can do is mount another knock sensor on the bell housing as close to the crank as possible, unplug the old one and plug the new one in. MaritimeMan did this years ago and AFAIK he has never had a problem with it. I tried to find a thread on it but could only find a few posts. Perhaps you will have better luck?? http://www.nissanpathfinders.net/forum/index.php?showtopic=574&view=findpost&p=3834 B Link to comment Share on other sites More sharing options...
RedPath88 Posted January 12, 2010 Share Posted January 12, 2010 I am merging your two threads on this topic together. And as I mentioned in the other, it appears that Nissan did not use a knock sensor on the VG30i's. They started in 1990 with the VG30e versions. I just called a dealer to verify and they said the same thing. There is no parts listing with Nissan for a KS on Pathfinders equipped with VG30i's Link to comment Share on other sites More sharing options...

Precise1 Posted January 12, 2010 Share Posted January 12, 2010 Maybe he did a body swap... B Link to comment Share on other sites More sharing options...
