    Code is: SA 16 DTC P24AF00

    This points to the PM/NOx sensor... would it only be the outlet sensor only, or can it also be for the inlet? Would cleaning it help in this scenario, or is it best to replace?

    Is the sensor just replace and go, without the threads fighting? Engine has not derated yet, but don't plan on using it until attempting to fix it. Does anti-seize do enough to help protect the threads or is there something better?

    Thanks.
