Can someone tell me the names of the 3 sensors on the back of the first gen b16 blcok near the oil filter, and wire colors if possible.

There are two 2 wire sensor and one 1 wire sensor. Where is the knock sensor located? Is that the 1 wire sensor?

Tring to locate the source of a problem on my car and I am thinking some of the wires may be crossed. Any easy ways to tell? I have no CEL light, just bogging and 3.5K-4K vtec on stock ECU

Thanks in advance, this problems driving me INSANE!

---------------------------------------

UPDATE:

Well it looks like I found a bit of a mess from the guy who put my engine in.

I have 2 green sensors (2 wire), they have a white wire with green stripe and a black wire, they are wired together and the one is in the spot of the knock sensor. The sensor in the knock sensor position doesn't have the white/green wire hooked up (which I am assuming is the feed).

Now I know the knock sensor is currently hooked up to the oil sensor (1 wire sensor beside the oil filter).

My question is what is the green sensor? I guess next step is to get a knock sensor, what all knock sensors will fit?

Make any sense? I know the dude was confused about the sensor on the back but WTF, I gave him all types of diagrams.


(not mine just so you can see what I mean)

UP I know someone knows the answer

 

BUMP

 

UP hoping to get answers today so I can fix my car.

 

UP AGAIN

 

JUST ADDED MY UPDATE TO THE B16 SAGA

 

Welcome to my world. I have crazy early vtec engagement, but not as early as yours. I get it at about 4200 rpm, i have a frist gen b16 no knock. Ill check my block for you tomorow in the Day light, I think all b series KS are the same.

 

 

the 3 sensors around the oil filter on your first gen b16a are:
-oil pressure sensor - 1 wire (yellow/red?)
-fan switch sensor - 2 wires (color?) on obd 1 car is located on thermostat housing.
-knock sensor - 1 wire (color?) green plug

I hope those info helps.....good luck

Would that be the green sensor just right & above of the Oil Filter? I think this is the sensor I have 2 of. The ones just grounded. I have a green 2 wire sensor where the knock sensor should be. It has a white green wire (feed) and a black wire (ground).

The oil sensor doesn't need re-wired does it? I just use whats on my stock B18A harness? (yellow/red wire)

If I am looking through the intake manifold the knock sensor should be near the middle right under the intake manifold correct?

The 1st gen B16A should have same oil pressure sensor as the your stock B18A, so yes you can just plug it in.

That is correct, knock sensor is located on the block above the oil filter right where intake manifold meets the block.
