Air Flow Meter/Sensor: Service and Repair
Mass Airflow Sensor with Intake Air Temperature Sensor Replacement
Removal Procedure
Note: Use care when handling the mass air flow (MAF)/intake air temperature (IAT) sensor. Do not dent, puncture, or otherwise damage the honeycell located at the air inlet end of the MAF/IAT. Do not touch the sensing elements or allow anything including cleaning solvents and lubricants to come in contact with them. Use a small amount of a non-silicone based lubricant, on the air duct only, to aid in installation.
1. Remove the air cleaner outlet resonator from the MAF/IAT sensor. Refer to Air Cleaner Resonator Outlet Duct Replacement (Service and Repair).
2. Disconnect the engine wiring harness electrical connector (2) from the MAF/IAT sensor (1).
3. Loosen the MAF/IAT sensor adapter clamp.
4. Remove the MAF/IAT sensor from the air cleaner assembly.
Installation Procedure
Note: The embossed arrow on the MAF/IAT sensor indicates the proper air flow direction. The arrow must point toward the engine.
1. Install the MAF/IAT sensor to the air cleaner assembly.
Caution: Refer to Fastener Caution (Fastener Caution).
2. Tighten the MAF/IAT sensor adapter clamp to 4 Nm(35 lb in).
3. Connect the engine wiring harness electrical connector (2) to the MAF/IAT sensor (1).
4. Install the air cleaner outlet resonator. Refer to Air Cleaner Resonator Outlet Duct Replacement (Service and Repair).
