Intake Air Temperature (IAT) Sensor (Trionic System)
Turn ignition off. Locate IAT sensor on intake manifold. Unplug connector from sensor. Measure resistance between sensor terminals at temperatures specified. See INTAKE AIR TEMPERATURE (IAT) SENSOR RESISTANCE (TRIONIC SYSTEM) table. Replace sensor if resistance is not as specified.
