Air Flow Meter/Sensor: Service and Repair
MASS AIR FLOW (MAF)/INTAKE AIR TEMPERATURE (IAT) SENSOR REPLACEMENTREMOVAL 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.
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.
4. Loosen the MAF/IAT sensor clamp at the air cleaner box.
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
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
Tighten the clamp to 4 N.m (35 lb in).
5. Connect the MAF/IAT sensor electrical connector (4).
