    I have a 2015 Freightliner Cascadia .. I have an active fault code Spn 3216 fmi 13. I’ve searched online and all the information I’m able to come up with is that there is no signal from the inlet nox sensor. I installed a new inlet sensor and the code is still active. Could the new sensor be defective? Any suggestion or info would be appreciated. Thanks.

    FMI 13 typically refers to a component being out of calibration, not component not responding.

    I just replaced mine on a 2014 Pete. They did a forced Regen and clear it.
