Air Flow Meter/Sensor: Service and Repair

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

REMOVAL PROCEDURE




1. Disconnect the mass air flow/intake air temperature (MAF/IAT) sensor electrical connector (4).




2. Loosen the air cleaner outlet duct clamp at the MAF/IAT sensor.
3. Remove the air cleaner outlet duct from the MAF/IAT sensor.




4. Loosen the MAF/IAT sensor clamp at the air cleaner box.

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.

5. Remove the MAF/IAT sensor.

INSTALLATION PROCEDURE

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




1. Install the MAF/IAT sensor.

NOTE: Refer to Fastener Notice in Service Precautions.

2. Tighten the MAF/IAT sensor clamp at the air cleaner box.

Tighten the clamp to 4 N.m (35 lb in).




3. Install the air cleaner outlet duct to the MAF/IAT sensor.
4. Tighten the air cleaner outlet duct clamp at the MAF/IAT sensor.

Tighten the clamp to 4 N.m (35 lb in).




5. Connect the MAF/IAT sensor electrical connector (4).
