2007 Cadillac Escalade Mass Air Flow Sensor Parts and Q&A

• Q: How to replace the Mass Air Flow Sensor/intake air temperature sensor on 2007 Cadillac Escalade?

  A: When replacing the Mass Air Flow Sensor and intake Air Temperature Sensor maintain careful handling of the Mass Air Flow Sensor/iat sensor to protect its honeycell at the air inlet end and refraining from contacting the sensing elements and exposing them to cleaning solvents or lubricants. A little non-silicone lubricant should be applied to the air duct for easier installation. The first step involves disconnecting the engine wiring harness electrical connector from the Mass Air Flow Sensor/iat sensor then proceeding to loosen the Mass Air Flow Sensor/iat sensor adapter clamp before removing the sensor from the air cleaner assembly. The installation of a new Mass Air Flow Sensor/iat sensor needs complete alignment of the embossed arrow marking to direct airflow toward the engine. Insert the sensor into the air cleaner assembly while fastening the Mass Air Flow Sensor/iat sensor adapter clamp to 4 n.m (35 lb in) torque and then reattach the engine wiring harness electrical connector to the Mass Air Flow Sensor/iat sensor.
