WARNING: This page is about a different car, the 1990 Toyota Land Cruiser and 1989 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
Remove sensor from side of EGR valve. Place threaded end of sensor and thermometer in container of oil. See Fig 1. Attach ohmmeter to sensor terminals. Heat the oil and note the resistance at specified temperature. See EGR TEMPERATURE SENSOR SPECIFICATIONS table. Replace sensor if not within specification.
