Nox sensor abnormal update rate./speed sensor

[DVT873]

Cummins has an emissions recall running on NH3 sensors and SCRs. C2119. On ISB 2350's for sure. The NH3 sensor is deleted and the SCR is replaced. I do not know if this applies to the ISX's. Quick Serve should tell you. Have had 3 customers have this done. There is some testing BS they had to pay for. Around $800 but the trucks came back with new SCR's and no NH3 sensors. As I recall. Poke ESN 73667326 for a 2350 ISB in and see what it says.

Something weird about QuickServe. The ESN above has had this done but it shows open in QS. Now when I see one I email Cummins to find out if it has been done or not. This might only be for the light and medium engines. Rawze will know the details.
