    how about fmi xx part of codes? post them so we can help you. What I can say this moment you may have a. bad nox sensor, b. not enough def injected because of def pump or just low quality def. Could be bad plv too or just low air pressure supply. post codes in this format spn xxxx fmi xx.

    He did give the FMI's:
    SPN 4364 - Low NOx Conversion Efficiency
    FMI 18 - Data Valid, but Below Normal Operating Conditions - Moderately Severe Level.
    This means that the reduction of NOx (inlet NOx to outlet NOx) is too low.

    SPN 3364 - DEF Quality Low
    FMI 02 - Data Valid, but Below Normal Operating Conditions - Moderately Severe Level.
    The is show that the DEF quality is poor. It could be a sensor issue, but since it's also seeing poor NOx conversion, you may have contaminated DEF. First I would check & replace the DEF filter and I'd pull the DEF doser and make sure it's clean. If you find any signs of contamination, draint he DEF tank and refill with new.

    It could be many things, but start there.

    that outlet nox sensor has short life because of location.
