RE: 2014 Pete 386 (09-29-2019 )GreenBean Wrote: It's showing SPN 3216 and 1387. These are the codes that are being displayed on the dash. I've cleaned the threads on the sensor and down just inside the exhaust as instructed. I'm open to any other suggestions? your dash display is obviously NOT showing cummins fault code(s). SPN: 3216 without the FMI # to go with the SPN number, it is almost completely meaningless ... it could be ANYTHING related to a NOx sensor and is NOT very helpful towards solving the actual problem!!! Without that FMI# (or at least the actual cummins engine fault code) --- it could be any one of the following errors... ------------------------- SPN: 3216 FMI: 16 Aftertreatment Intake NOx - Data Valid But Above Normal Operating Range - Moderately Severe Level. A high engine out nitrogen oxide (NOx) condition has been detected. I.E.> - NOx levels in the exhaust is simply too high, nothing wrong with sensor. ------------------------- OR.... ------------------------- SPN: 3216 FMI: 10 Aftertreatment Intake NOx Sensor - Abnormal Rate of Change. The aftertreatment intake nitrogen oxide (NOx) sensor reading is not valid. I.E.> Invalid data / incompatible NOx sonsor for the enigne /NOx sensor is not communicating properly on the J1839 bus. ------------------------- OR... ------------------------- SPN: 3216 FMI: 20 Aftertreatment Intake NOx Sensor - Data Not Rational - Drifted High. An offset in the intake nitrogen oxide (NOx) sensor reading has been detected. I.E.> The NOx sensor is out of calibration, or is reading too high only when the engine is at idle. ------------------------- OR ... ------------------------- SPN: 3216 FMI: 13 Aftertreatment Intake NOx - Out of Calibration. A calibration mismatch between the aftertreatment intake nitrogen oxide (NOx) sensor and the engine control module (ECM) has been detected. I.E.> An incompatible NOx sensor has been installed for that model engine. ------------------------- OR... ------------------------- SPN: 3216 FMI: 2/2 Aftertreatment Intake NOx Sensor - Data Erratic, Intermittent, or Incorrect. An incorrect nitrogen oxide (NOx) sensor reading has been detected by the aftertreatment intake NOx sensor. I.E.> The Nox sensor has a wiring or communications issue. ------------------------- OR... ------------------------- SPN: 3216 FMI: 4 Aftertreatment Intake NOx Sensor Circuit - Voltage Below Normal or Shorted to Low Source. An internal circuit error has been detected by the aftertreatment intake nitrogen oxide (NOx) sensor. I.E.> Nox sensor is grounded out due to bad wiring or plug problem. ------------------------- OR... ------------------------- SPN: 3216 FMI: 9 Aftertreatment Intake NOx Sensor - Abnormal Update Rate. No communication or an invalid data transfer rate has been detected on the J1939 data link between the engine control module (ECM) and the aftertreatment intake nitrogen oxide (NOx) sensor. I.E.> Nox sensor is not sending signals fast enough to the ecm .. it could be the NOx sensor, or it could be some other device (like the turbo, egr valve, a different nox sensor, or a number of things) tieing up the J1939 bus by sending signals too frequently, CAUSING THE ONE WITH THE ERROR NOT TO BE ABLE TO SEND SIGNALS OFTEN ENOUGH. ------------------------- OR any number of other faults related to NOx sensors. <<_-- TAKE YOUR PICK!!! -- WITHOUT THAT FMI NUMBER OR THE ACTUAL CUMMINS FAULT CODE -- YOUR DOING NOTHING BUT GUESSING!
