Higher

Smaller

5. If the value deviates from the standard value or 

the resistance remains unchanged, replace the 
No. 2 exhaust gas temperature sensor (catalyst 
temperature) assembly.

6. Install the No. 2 exhaust gas temperature sensor 

(catalyst temperature) and tighten it to the 
specified torque.

Tightening torque: 30

CAUTION

• When the exhaust differential pressure sensor is replaced, use the M.U.T.-III to initialise the learn-

ing value (Refer to GROUP 00 

− Precautions before Service, Initialisation Procedure for Learning 

Value in DPF System ).

• When the exhaust differential pressure sensor is replaced, perform the forcible DPF regeneration 

after learning value in DPF system (Refer to 

P.17-46

).

• When the No.1, No.2 or No.3 exhaust gas temperature sensor is replaced, perform the forcible DPF 

regeneration (Refer to 

P.17-46

).
