Sensor, Temperature, Intake Manifold: Description
The intake air temperature sensor (1) is located before the air flow control valve in the rear of the air inlet tube. The intake air temperature sensor (1) measures the temperature of the air as it is supplied to the cylinders and transmits the value to the Powertrain Control Module (PCM). This is required in order to determine the density of the air being supplied for the combustion process. The value range is from minus 40°F up to 311°F (minus 40°C to 155°C).
