Spn 1326 fmi 11 and spn1322 fmi 11 - Nikolay - 12-15-2022
2016 m2 freightliner ISL9 cm2350 the codes comes and goes. Engine working with no any difference. Computer shows no active codes. Any ideas what can it be?

Those are both misfire codes relating to the exhaust gas pressure sensor. Bad sensor or wiring to the sensor.
Do you have insite? If so you can monitor the exhaust gas pressure and see if its wonky. I'm surprised it's running ok with this going on though.

That what I thought, I checked yesterday this sensor everything looks fine nothing is wonky

Maybe there is a small tube clough?

Do an EGR tuneup, how old is the sensor you say is good? I replace my exhaust back pressure sensor every say two years +/-, same with the intake manifold pressure sensor.

No I'm just saying it's looks good, but I'm already ordered the new sensor. Will keep you posted. Thank you all

Guys thanks a lot...
The problem solved, I replaced two sensors that you suggested. Truck runs perfect.
Thanks again
