D2 V8 camshaft position sensor

Hi All
I'm a bit stuck and hoping for help.
I've gone to replace the camshaft position sensor today. When it was MOT's they said it was showing a fault, and sure enough when i scanned it it was.
But, its up on ramps atm, with the oil filter out, and for the life of me i cant see it?
It doesn't quite resemble the workshop manual pic down there so i was hoping i'm being a dope and someone can point it out (pic attached)
I've got a horrid feeling there may have been a bodge done on it somewhere down the line.
Thought i'd do all the o2 sensors while i was there, and it seems the post cats have been removed?
As as an aside the nanocom is throwing up p1000 camshaft sensor fault/value. timing error drive cycle C.
occurred 126 times. signal invalid.
Thanks in advance
Matt

Well turns out I'm looking in the wrong place.
It's behind the crank pulley.
Would anyone know if you need to take the pulley off? Going to try without.

Hi anyone interested.
Hardest thing about doing it is.
Finding it when it's caked on oil.
And mistaking the tab to release the connector, with the tab that releases the connector from the harness connector.
