Second,  there is a small sensor that appears to be installed in a

oil

passage on the plugs side of the engine.  Its toward the back and

can be

seen

in the same pic with the sensor described in the paragraph above.  I

think it

is an oil temp sensor but still not sure.  It appears that this is

the

usual

location of a oil pressure sensor on a 13B but I'm pretty sure that

this

in

not a pressure sensor.  Again, any ideas would be helpful.  I have

not

yet

been able to identify a sensor that looks like an oil pressure

sensor.

it provides water temp signal for the dashboard of the vehicle.

Really? That is interesting. Is it a turbo? This is definitely a knock
sensor. The screw hole that mounts this on all late rotor housings
does not go through to the water jacket.

You're pointing at a knock sensor all right, but this wasn't the sensor I'm
referring to. My application is a non-turbo. The original text referred to a
small sensor, wondering what it does, perhaps some oil function. In the same
JPEG you posted, you can see the water temp sensor adjacent to the knock
sensor. Physically it's about 35mm away from the knock sensor. It's a tiny
bugger with two male blade connections, which makes a nice snakebite-like
mark in your wrist when working in this area.

Yes. I was wrong as I missed the second part of your message.
That is indeed the oil temp sensor.
