Inspect and clean if necessary airflow thermistor. The thermistor can be seen from the top of the
manifold.
IMPORTANT: Ensure the unit is switched off.

Be careful not to move the alignment of the thermistor. The thermistor must be aligned central to
the hole in the correct orientation, refer to the diagrams above.
