94 pathfinder VG30E knock sensor and FSM EF & EC 137

[khawks]

The FSM states to check knock sensor by checking for continuity between pin e of the harness and ground. page 137 of EF & EC continuity should exist.

Well it does not, pin e is the signal wire, there is no wire at all for the ground side of the sensor in the harness, even though the Hitachi/Asimo or whatever new name is has two pins on the knock sensor. (my old KS was definitely bad/cracked)

Did prior years use a 2 wire harness? Just wondering why the FSM is in error unless I am missing something?

I have read various opinions on whether the ECM adjusts timing based on KS signal/voltage. I would think that is the entire point of having a KS and I know from experience in subaru EJ25s that they run just like my pathy does right now if the KS is bad. First time on a VG30E for me.

 

I am chasing down intermittent stumble and lag like so many have posted before me. Failed emissions high HC and 
CO, all plugs black, and you can see it in the tailpipe and smell it.

The solenoid for my AAC is bad as well, ordered a sentra AACV in the hopes the solenoid might fit.

temp sensor is nominal, temp gauge nominal, MAF clean and nominal, swapped distributors no change.

I have reman injectors from rock auto but am waiting on the sentra AACV part before installing.

If it doesnt fit I plan on plugging up the vacuum lines and manually adjusting idle.
