I have a 1983 280zx turbo motor and there is a sensor on the passenger side left of the oil filter and between the oil filter and the oil dip stick.  now on the other side of the oil filter is the oil pressure sensor but I do not know what this one is . it reads normal open with a ohm meter and has 2 electrical connections on it and screws into the block. I am thinking it might be temperature and if so if I can use it for controlling my electric cooling fan. thanks

think its a knock sensor

 

yes Dave I am not sure what this is also,  if I can not use it I would like to plug it up if I can find what the thread size is ?

It screws into the block, or the head?

You got a pic?

From page 62 of section EFEC:

 

yes Steve that is it thanks I guess I will remove it , looks like I can not use it .  do you know if there is fluid behind it being it is a knock sensor ? do I need a plug or can I just remove it ? thanks kully

I think the same thing but I do not want to remove it with be sure as I do not have a plug for it !
