Default What sensor is this?

What that's green sensor right above the oil filter?
I just found out that it was missing when I was swapping my GSR manifold.
And I've been driving w/o it for 6 months.

I think that might be the knock sensor. But if you're running without the sensor then you should be getting a CEL (if you weren't already). With OBD2 you'll be thrown into limp mode (no Vtec, limited revving) but if you're using a chipped or otherwise altered ECU you will still be running fine.

Yep. Definitely your knock sensor. You said you were missing it? Any CEL's?

that is the knock sensor. I guess your ECU doesn't care.

Some of the older B series block have the "thermoswitch" or coolant temp sensor right there. But that does look like a knock sensor to me.

No, none of the B series EVER had a thermal switch there. The thermalswitch sits about 5" lower then that beside the oil filter. NOT above it. It also has two terminals on it similar to the oil pressure sending unit. That *IS* the knock sensor.

Youre right, i pictured that location after you posted and that is where it is located. That is the knock sensor indeed.

if the ECU is chipped it could be ignoring the knock sensor.. which is a good thing.

I guess it's the knock sensor then.
I always thought knock sensor was directly below the intake mani?

How much more "directly under the intake manifold" do you want it? It has to be next to the cylinders since its job is to monitor knock. So what do you want?

lol I wonder if he knows what an intake manifold is?

EDIT: after re-reading his first post "swapping GSR manifold" it would appear that he does. now I'm really confused
