IAT Sensor Resistance
WARNING: This page is about a different car, the 1995 Lexus SC 400. However, it is still accessible from the selected car via links, so may be relevant.
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.
