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. Remove the air cleaner outlet resonator.
2. Disconnect the engine wiring harness electrical connector (1) from the MAF/IAT sensor.
3. Loosen the MAF/IAT sensor seal clamp (1).
4. Remove the MAF/IAT sensor from the air cleaner assembly.
