Intake Air Temperature (IAT) Sensor
IAT sensor is located on intake manifold. The IAT contains a Red/Black and Gray/Yellow wire connector. Using ohmmeter, check resistance across IAT sensor terminals. Replace IAT sensor if resistance is not within specification. See IAT SENSOR RESISTANCE SPECIFICATIONS table.
