I can not locate all 4 CPS units, please help
Hi guys,
So it seems pretty clear after reading so many post here that there are FOUR CPs units on my 276.9** Engine. I thought there were only TWO after recently removing the intake manifold.
The two I saw were right up front and obvious as could be, I kinda new that must have been too good to be true! But I have tried find the other two which I am assuming are located in the rear
and I am not having any luck. Does anyone have a link to a video perhaps that shows the location of all the sensors or at least the rear two?
I had already purchased replacements for the front units but I had not installed them yet. Then this morning I removed the ECU to look for signs of a water leak and as soon as I unplugged the ECU I saw
a small amount of oil in the socket, so now I am worried. I want to go ahead and do this repair soon.
As always thanks in advance for any help/ info.

UPDATE 2:
So after taking another closer look and knowing where to look I did indeed find the other CPS units and I am ready to tackle the change out as soon as I get the new parts.
Thanks again!
