Air Flow Meter/Sensor: Service and Repair
Mass Airflow Sensor/Intake Air Temperature Sensor Replacement
Removal Procedure
Important: 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. Disconnect the engine wiring harness electrical connector (1) from the MAF/IAT sensor.
2. Remove the MAF/IAT sensor screws (1).
3. Remove the MAF/IAT sensor (2) from the air cleaner upper housing.
