MASS AIR FLOW (MAF)/INTAKE AIR TEMPERATURE (IAT) SENSOR REPLACEMENT
REMOVAL PROCEDURE
IMPORTANT: Use 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 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 duct.
2. Pull out the gray connector position assurance (CPA) retainer.
3. Push down on the black clip in order to disconnect the MAF/IAT sensor electrical connector (4).
4. Loosen the MAF/IAT clamp.
5. Remove the MAF/IAT sensor from the air cleaner assembly.
INSTALLATION PROCEDURE
IMPORTANT: The embossed arrow on the MAF/IAT sensor indicates the proper air flow direction. The arrow must point toward the engine.
1. Locate the air flow direction arrow (2) on the MAF/IAT sensor.
2. Install the MAF/IAT sensor to the air cleaner assembly.
NOTE: Refer to Fastener Notice in Service Precautions.
3. Tighten the MAF/IAT clamp.
Tighten the clamp to 7 N.m (62 lb in).
4. Connect the MAF/IAT sensor electrical connector (4).
