B815H21306013
Removal
1) Remove the air cleaner box. Refer to “Air Cleaner
Box Removal and Installation in Section 1D
(Page 1D-6)”.
2) Remove the IAT sensor (1) from the air cleaner box.
Installation
Install the IAT sensor in the reverse order of removal.
Pay attention to the following point:
• Tighten the CMP sensor screw (1) to the specified
torque.
Tightening torque
IAT sensor mounting screw (a): 5.5 N·m (0.55 kgf-
m, 4.0 lb-ft)
IAT Sensor Inspection
B815H21306014
Refer to “DTC “C21” (P0110-H/L): IAT Sensor Circuit
Malfunction in Section 1A (Page 1A-52)”.
Inspect the IAT sensor.
NOTE
IAT sensor resistance measurement method
is the same way as that of the ECT sensor.
Refer to “ECT Sensor Inspection (Page 1C-
5)”.
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.
