(4) Loosen the fastener on the electrical parts box and unbind
the lead wires.
(5) Loosen the clamp for the lead wire in the rear of the
electrical parts box.
(6) Pull out the thermistor <2-phase pipe> (TH6) from the
sensor holder.
Note1: When replacing thermistor <2-Phase pipe>(TH6),
replace it together with thermistor<Ambient> (TH7),
since they are combined together.
Refer to No.5 below to remove thermistor <Ambient>.
