1C-13 Engine Electrical Devices: 

Mass Air Flow (MAF) and Intake Air 
Temperature (IAT) Sensor On-Vehicle 
Inspection

S5JB0A1306019

NOTE
Before performed this inspection, be sure to 
read the “Precautions of ECM Circuit 
Inspection:  in Section 1A”.

 

1) Disconnect MAF and IAT sensor connector.
2) Connect voltmeter to “BLU/BLK” wire terminal (2) of 

MAF and IAT sensor connector (1) disconnected and 
ground.

3) Turn ON ignition switch and check that voltage is 

battery voltage.
If not, check if wire harness is open or connection is 
poor.

4) Turn OFF ignition switch and connect connector to 

MAF and IAT sensor.

5) Connect special tool between ECM and ECM 

connector referring to “Inspection of ECM and Its 
Circuits:  in Section 1A”

6) Turn ON ignition switch and check MAF signal 

voltage between “C37-26” terminal circuit and “C37-
27” terminal circuit of special tool.

MAF signal voltage between “C37-26” terminal 
circuit and “C37-27” terminal circuit of special 
tool
MAF signal voltage of MAF and IAT sensor with 
ignition switch turned ON: 0.5 – 1.0 V

7) Start engine and check that voltage is lower than 5 V 

and it rises as engine speed increases.

MAF signal voltage between “C37-26” terminal 
circuit and “C37-27” terminal circuit of special 
tool
MAF signal reference voltage of MAF and IAT 
sensor at specified Idle speed: 1.3 – 1.8 V

8) If check result is not as specified above, cause may 

lie in wire harness, connector connection, MAF and 
IAT sensor or ECM.

Mass Air Flow (MAF) and Intake Air 
Temperature (IAT) Sensor Removal and 
Installation

S5JB0A1306020

CAUTION

!

 

• Do not disassemble MAF and IAT sensor.
• Do not expose MAF and IAT sensor to any 

shock.

• Do not clean MAF and IAT sensor.
• If MAF and IAT sensor has been dropped, it 

should be replaced.

• Do not blow compressed air by using air 

gun or the like.

• Do not put finger or any other object into 

MAF and IAT sensor. Malfunction may 
occur.

 

Removal

1) Disconnect negative cable at battery.
2) Disconnect MAF and IAT sensor connector.
3) Remove MAF and IAT sensor (1) from air cleaner 

case.
