6) Loosen the TP sensor mounting screw (1) using the
special tool and turn the TP sensor to bring the bar
to the correct position.
Special tool
: 09930–11950 (Torx wrench)
7) Tighten the TP sensor mounting screw to the
specified torque.
Tightening torque
TP sensor mounting screw: 3.5 N·m (0.35 kgf-
m, 2.5 lbf-ft)
8) Turn off the engine and install the removed parts.

B944H11306024
Removal
1) Lift and support the fuel tank. Refer to “Fuel Tank
Removal and Installation in Section 1G (Page 1G-
7)”.
2) Disconnect the IAT sensor coupler (1).
3) Remove the IAT sensor (2).
Installation

IAT Sensor Inspection
B944H11306026
Refer to “DTC “C21” (P0110-H/L): IAT Sensor Circuit
Malfunction in Section 1A (Page 1A-53)”.
NOTE
IAT sensor resistance measurement method
is the same way as that of the ECT sensor.
Refer to “ECT Sensor Inspection (Page 1C-
4)”.
CAUTION
!
• The IAT sensor operative temperature
range is –30 – 120 °C (–22 – 248 °F).
• Do not heat the oil up to 120 °C (248 °F) or
more for this inspection.
