INTAKE TEMPERATURE & PRESSURE SENSOR   OPERATION The Inlet Air Temperature/Pressure Sensor is a combination dual-function sensor. The sensor element extends into the intake air stream at the top of the air filter housing. Ambient air temperature, as well as barometric pressure, is monitored by this sensor. The Engine Control Module (ECM) monitors signals from this sensor.   REMOVAL The Inlet Air Temperature/Pressure Sensor (3) is located on the air cleaner cover. 1.

MASS AIR FLOW SENSOR (MAF)   OPERATION The Mass Airflow (MAF) sensor is a frequency based device. A constant voltage is applied to a heated wire on the sensor. This wire is positioned in the air cleaner air stream and is heated by the electrical current that the voltage produces. As air flows across it, it cools down. The heated wire or film is a positive temperature coefficient resistor. This means that its resistance drops when its temperature drops. The drop in resistance allows m
