Intake Air Temperature (IAT) Sensor
Intake Air Temperature (IAT) Sensor is located inside air cleaner case. The IAT sensor contains a light green/black and gray 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.
