Yeah, in the manifold - watch how the intake temperature increases when you come off the throttle (no airflow over the sensor so it heats up) then drops again when you floor it.

Also watch how much time it takes to cool down when you've been sat in traffic - heatsoak.

the intake temp sensor is on the manifold next to the throttle body (a black plug)


not the same hole that Bigjode was wondering what was in there?
 
nah lol they were on about a tiny screw hole on the side of the manifold

the intake temp sensor is a big black plug on the front of the manifold

i know only because when i tried sanding down my manifold i unplugged it and drove off forgetting to plug it back in and so 1 fault code later i realised
