Air Flow Meter/Sensor: Service and Repair

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

REMOVAL PROCEDURE




1. Disconnect the mass air flow/intake air temperature (MAF/IAT) sensor assembly harness connector.




2. Separate the MAF/IAT sensor assembly and the air inlet tube by loosening the hose clamp.

NOTE: Handle the MAF/IAT sensor carefully. Do not drop the MAF/IAT sensor. Do not damage the screen located at the air inlet end of the MAF/IAT. Do not touch the sensing elements. Do not allow solvents and lubricants to come in contact with the sensing elements. Use a small amount of SPO P/N 12345884 lubricant or the soap based equivalent in order to aid in the installation.




3. Disconnect the MAF/IAT sensor assembly from the air cleaner cover by loosening the hose clamp.

INSTALLATION PROCEDURE

IMPORTANT: Ensure to point the flow arrow on the MAF/IAT sensor assembly away from the air cleaner assembly.

NOTE: Refer to Fastener Notice in Service Precautions.
