What does the ni22365-ey0013 pressure sensor actually read if it's mounted on the distributor. Crank case pressure?

This is our final conclusion.....Somebody replaced the harness for sure..I also checked 10 units in my back yard and all of them have the connector..Anyway, I delivered the truck with code, as it is working perfect. Lets see if client start complaining.....I hope not.....Thanks a lot..

Sorry Gabriel I checked and all my units have the harness connection right beside dist placement (old)
Is it possible someone changed harness before you were called in ?

Post your e-do addy in your profile and you might receive. Better yet tell you Nissan dealer to look in parts catalog under engine electrical then distributor. Trust me, its there.

What i used to do all day now takes me all day to do.
I don't suppose any of you dealer guys can find a part number for the sensor my dealer sent me a one wire oil pressure sensor and even after seeing the picture can not identify the sensor

I used key on with engine off to locate it
just pull up the monitor screen and scroll down to #22 I think
(ATM pressure) and unplug it. it will go to 0 mv and then plug it back in try it no one was more shocked than I was

Thats a new one on me as i have many of these units to keep up. If it is what you are describing then it is a pressure sensor for? As i don't think it is for ATM (auto trans) but i will remove one to see if it possibly linked to engine oil pressure. I am betting more on a barometric sensor if anything. Seen it but never questioned it as i have never had to fool with it. Thanks for the info!

after doing some research on nissan obdI systems which i think this truck has? it refers to an O2 sensor fault
could be wrong though, everywhere i looked in cat's nissan based codes it stops at DTC-41
