EGR Temperature Sensor
Turn ignition off. Disconnect negative battery cable. Remove EGR temperature sensor. See COMPONENT LOCATIONS under INTRODUCTION. With sensing portion of EGR temperature sensor submerged in hot oil, measure resistance between terminals. Replace EGR temperature sensor if resistance is not as specified. See EGR TEMPERATURE SENSOR RESISTANCE table.
