Air Flow Meter/Sensor: Service and Repair

MASS AIR FLOW (MAF)/INTAKE AIR TEMPERATURE (IAT) SENSOR REPLACEMENT

TOOLS REQUIRED
J 22610 Service Boot Clamp Installer

REMOVAL PROCEDURE

IMPORTANT: Take care when handling the mass air flow/intake air temperature (MAF/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. Do not allow anything, including cleaning solvents and lubricants, to come in contact with the sensing elements. Use a small amount of a non-silicone based lubricant on the air duct only, to aid in the installation. Do not drop or roughly handle the MAF/IAT sensor.




1. Disconnect the electrical connector of the MAF/IAT sensor.
2. Remove the air intake duct clamps from the MAF/IAT sensor and the throttle body.




3. Remove the air duct clamp at the air cleaner housing.




4. Remove the MAF/IAT sensor.

INSTALLATION PROCEDURE

IMPORTANT: The embossed arrow on the MAF/IAT sensor indicate the proper air flow direction. The arrow must point toward the engine.




1. Install the MAF/IAT sensor into the air intake duct at the air cleaner housing.




2. Install the new clamp using the J 22610.




3. Install the air intake duct to the MAF/IAT sensor and the throttle body.
4. Install the clamps.
5. Connect the electrical connector of the MAF/IAT.
