Hello colleagues,
I have a problem with my Renault Master III 2.3dci engine code : M9TC704 2017 year.
The van runs well dont goes into limp mode, but check engine light lights up after engine runs 5-10 minutes.
I check with diagnostic tools there is stored faults in Urea dosing module :
DTC220312 Upstream nitrogen oxide sensor open circuit
DTC22o312 Upstream nitrogen oxide sensor Short-circuit to +12V.
I tried to disconnect Nox sensors, but stores different faults in the module, also tried to disconnect the others sensons on the exhast pipes, but cant find the problematic, because dont store the fault immediatly, it takes some time to store it.
I will be so gratefull if anyone can help me to locate, which is this sensor to check it and change it .
