Do you know where the manifolds are? Look at engine from the front, right side intake, left side exhaust.
2007
A=213-1649
B=213-3519

2008-2010
213-4223

thank you hummerz- i have a 0017 code which would be 'sensor B' circuit.
is sensor b located behind/under alternater?
is 213-4223 the OE part number ? if so both sensor A& B are the same ?
my H3 is 2010 3.7 there is a cam sensor front passenger side of head.-none on driver's side unless it is beween intake manifold runners or closer to alternator.
i haven't taken anything apart yet, but would like to see sensor B first - i can't find it.

the diagrams are great , at least i now know that 'B' is easy to get at.
BUT on my 3.7 there is no camsensor in the location as per the diagram for 'A'.
