REMOVAL
To remove the manifold, the throttle body must
be removed (see previous pages).
There are no special notes for removal.
The inlet manifold is fitted with an electrical
heater (2) with a PTC type resistance (positive
temperature coefficient).
This is mounted in the inlet manifold, opposite
the throttle, and is secured by a circlip.
The heater is fed via a relay by the computer up to
a coolant temperature of 68°C.
If the coolant temperature sensor is faulty, the
heater is permanently fed.
