IAT Sensor Resistance
Turn ignition off. Disconnect electrical connector from VAF sensor. See COMPONENT LOCATIONS under INTRODUCTION. Measure resistance between terminals THA and E2. See Fig 1. Replace sensor if resistance is not as specified. See INTAKE AIR TEMPERATURE (IAT) SENSOR RESISTANCE table.
