• Q: How to replace the Mass Air Flow Sensor on 2002 Chevrolet Avalanche 2500?

  A: The first step for replacing the Mass Air Flow Sensor/intake air temperature (MAF/IAT) sensor involves handling the sensor gently to preserve the air inlet honeycell structure while staying away from sensor elements and refraining from exposing them to cleaning materials or lubricants. You should apply a small amount of non-silicone based lubricant to the air duct for assembly purposes. Start by taking off the air intake resonator followed by disconnecting the Mass Air Flow Sensor/iat sensor electrical connector. Start by loosing the clamp which holds the Mass Air Flow Sensor/iat sensor to the air cleaner housing before removing it from the assembly. When installing the Mass Air Flow Sensor/iat sensor keep its embossed arrow facing the engine direction followed by attachment to the air cleaner housing with clamp tightening. The Mass Air Flow Sensor/iat sensor electrical connector should be connected after which the device's air intake resonator can be installed.
