2021 MX13 pac car dpf and scr efficiency issues in need of egr tuneup

[mikkhh]

Oh well again DPF faults on second MX13

Diff pressure sensor is reading 14hPa with ignition on, engine off. That is BAD. Should read ZERO. New sensor will be ordered from Netherlands Paccar, have more trust in them than dealer.

Will pull whole exhaust to replace sensor AND clean pipes, to make sure that they are not blocked. Will order new dpf seals etc and try to clean SCR doser too then.

Will pull temperature sensors and test them using propane torch, to make sure they are not getting stuck.


Have attached photos why it is must to clean out pressure sensor tubes.
