Millenia 2.3L
- Vehicle is equipped with 3 different IAT sensors. Each IAT sensor has unique resistance characteristics. IAT sensors are located in air filter housing, dynamic chamber at right rear of engine, and in Lysholm compressor on top right of engine.
- Remove IAT sensor(s) to be tested. Place IAT sensor and thermometer in a container of water. Connect ohmmeter between IAT sensor terminals. Slowly heat water. Observe resistance reading at specified temperatures. See IAT SENSOR RESISTANCE SPECIFICATIONS (MILLENIA 2.3L) table. If resistance is not as specified, replace IAT sensor.
