Exhaust Gas Temperature Sensor (Calif. Models)
- Remove exhaust gas temperature sensor, located below EGR valve. Place sensing portion of exhaust gas temperature sensor in water.
- Gradually heat water and read resistance values across terminals. See EGR TEMPERATURE SENSOR RESISTANCE
table. Replace exhaust gas temperature sensor if not within specification.EGR TEMPERATURE SENSOR RESISTANCE
