    Does anyone know if it is possible to use a qls sensor from a smaller tank? I have a 23 gallon tank but may be able to get a sensor from a smaller tank.

    Thank you.

    Interesting question. In theory it should, except for maybe the level not being accurate.

    Ok, so my truck is still having the SCR issues. I called the local dealer and spoke to one of the guys I normally deal with there and he told me that there was another step for this "QLS Emergency Calibration". He told me that I had to cut the pigtail on the QLS side and seal them. I asked if he had any set of procedures that he can give me and he printed them out for me. I'm attaching them here. I will be doing this QLS sensor removal today on our truck and will keep everyone posted in the next few days when the truck gets used.

    Great information. I wish they would have made a new alert for us as I see this update is over a week old now. Sad how sometimes the information and communication is better here than it is from the OEMs. Thanks for sharing. I let my shop know about this update.

    So how would someone search this up? Does it have to be a dealer? Or can it be found on navistar? If it is on navistar where would the alert for something like this be?

    What he gave you is a print out from our service site that the dealers log into. That is dealer only.
