EGR Temperature Sensor (Calif.)
- Sensor is threaded into EGR valve. Disconnect negative battery cable. Disconnect 2-wire connector from sensor and remove sensor. Position sensor threads in container of water with thermometer. connect ohmmeter leads to sensor terminals.
- Apply heat to container until water reaches specified temperature. See EGR TEMPERATURE SENSOR RESISTANCE table. Replace sensor if resistance is not within specification.
