How to replace the Mass Air Flow Sensor on GMC Envoy?

You must handle the sensor gently to avoid damaging the air inlet honeycell area when replacing it since all substances including cleaning fluids must stay away from the sensing elements that should remain untouched. The air duct will benefit from a minimal quantity of lubricant which does not contain silicone for installation assistance. The installation process starts with disconnecting the Mass Air Flow Sensor/iat sensor from its engine harness electrical connector before removing all securing screws to extract the sensor. To install the new Mass Air Flow Sensor/iat sensor position it and fasten it with screws that should be tightened to 0.6 n.m (5 lb in) as per the fastener notice. The last step involves reconnecting the engine harness electrical connector back to the Mass Air Flow Sensor/iat sensor.
