K20 Engine Control Module

The control module contains a microprocessor used to process input data to control outputs.
The control module controls a series of actuators to ensure optimal engine performance. The control module does this by reading values from a variety of sensors, interprets the data and adjusts the engine actuators accordingly.

B65 Intake Manifold Pressure and Air Temperature Sensor

The assembly has several functions :
Pressure
The signal voltage increases when the pressure increases.
Temperature
The temperature sensor is a negative temperature coefficient thermistor, a resistor which changes based on temperature.

Low temperature produces a high resistance : 49, 882 ohms @ -40°C (-40°F)
High temperature produces a low resistance : 67 ohms @ 150°C (302°F)

Compressor Air Intake Turbocharger System Description
The intake air temperature sensor 1 and the intake manifold pressure sensor are integrated in the same housing, which is located behind the throttle body.The sensor measures the temperature and pressure in the intake manifold between the throttle valve and the intake valves.
