Inspection

1.	Turn the ignition switch OFF.

2.	Disconnect the IATS connector.

3.	Measure resistance between the IATS terminals 3 and 4.

Check that the resistance is within the specification.

Temperature [°C(°F)]	Resistance (k?)
-40(-40)	40.93 ~ 48.35
-20(-4)	13.89 ~ 16.03
0(32)	5.38 ~ 6.09
10(50)	3.48 ~ 3.90
20(68)	2.31 ~ 2.57
40(104)	1.08 ~ 1.21
50(122)	1.56 ~ 1.74
60(140)	0.54 ~ 0.62
80(176)	0.29 ~ 0.34

Removal

1.	Turn the ignition switch OFF and disconnect the battery negative (-) terminal.

2.	Disconnect the manifold absolute pressure sensor connector (A).

3.	Remove the mounting bolt (B), and then remove the sensor from the surge tank.

Installation

•	Install the component with the specified torques.

•	Note that internal damage may occur when the component is dropped. In this case, use it after inspecting.

•	Insert the sensor in the installation hole and be careful not to damage when installation.

Install in the reverse order of removal.
