Exhaust Gas Recirculation Temperature (EGRT) 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 EGRT SENSOR RESISTANCE table. Replace sensor if resistance is not within specification.
