Did you see the label on the middle left of this image...

Ugh! That's what I was afraid of!

I have a replacement part and the probe is about 6 inches long.

I'm guessing I have to drop the motor to replace it.

Thx for the response and photo

No the oil pressure sensor is only about as large as you see and can be replaced with the engine in place.

Are you really asking about the oil level sensor?

[Sheriff John]

Uh oh, I have a feeling that I haven't done my homework.

I have a intermittant on my oil pressure guage. Every now and then, the pressure drops to zero, 15 seconds or so, it pops up to normal.

Connection or sensor to me. So a while back, I was on the phone with Suncoast and asked to include a oil pressure sensor with my order.

Crud! I just went to my garage and checked the part. I got a oil LEVEL sensor.

Serves me right, I should have pulled the number from my manuals before I ordered.

I would think that you can replace the pressure sensor with out too much cursing. Don't you think?

Thanks for the help

[Loren]

Yup, a crow-foot wrench is handy for it though (unless you have small hands and small wrenches).

Hi Folks,

Just finished putting my engine/trans back into my 2000 996 and for the life of me I cannot find where this connector goes. Any help would be appreciated! Please see attached.
