EGR Temperature Sensor: Testing and Inspection

1. DRAIN ENGINE COOLANT





2. REMOVE V-BANK COVER
3. REMOVE EGR VALVE
EGR Valve





4. REMOVE EGR VALVE ADAPTOR
(a) Disconnect the EGR gas temperature sensor connector.
(b) Disconnect the PCV hose from the EGR valve adaptor.
(c) Remove the 2 bolts, 2 nuts, V-bank cover bracket, EGR valve adaptor and gasket.





5. REMOVE EGR GAS TEMPERATURE SENSOR FROM EGR VALVE ADAPTOR
(a) Mount the EGR valve adaptor in a vise.
(b) Remove the EGR gas temperature sensor from the adaptor.
(c) Remove the connector bracket from the sensor connector.








6. INSPECT EGR GAS TEMPERATURE SENSOR
Using an ohmmeter, measure the resistance between the terminals.
Resistance:
If the resistance is not as specified, replace the sensor.
7. REINSTALL EGR GAS TEMPERATURE SENSOR TO EGR VALVE ADAPTOR
(a) Mount the EGR valve adaptor in a vise.
(b) Install the EGR gas temperature sensor to the adaptor.

Torque: 20 N.m (200 kgf.cm, 14 ft.lbf)

(c) Install the connector bracket to the sensor connector.
8. REINSTALL EGR VALVE ADAPTOR
(a) Install a new gasket, the EGR valve adaptor, connector bracket and V-bank cover bracket with the 2 bolts and 2 nuts.

Torque: 19 N.m (195 kgf.cm, 14 ft.lbf)

NOTICE: Do not touch the air intake chamber and adaptor surfaces of the gasket with your hand.

(b) Connect the PCV hose to the EGR valve adaptor.
(c) Connect the EGR gas temperature sensor connector.
9. REINSTALL EGR VALVE
10. REINSTALL V-BANK COVER
11. REFILL WITH ENGINE COOLANT
