REMOVAL AND INSTALLATION


caution
  • When the exhaust differential pressure sensor or exhaust differential pressure sensor ambient air temperature sensor is replaced, use the M.U.T.-III to initialise the learning value (Refer to GROUP 00 - Precautions Before Service, Initialisation Procedure for Learning Value in DPF System .)
  • When the exhaust differential pressure sensor or exhaust differential pressure sensor ambient air temperature sensor is replaced, perform the forcible DPF regeneration after learning value in DPF system (Refer to .)
  • When the exhaust ambient pressure sensor is replaced, perform the forcible DPF regeneration (Refer to .)
