You didn't say what engine your talking about here but I'll assume it's a 2350?? If so then 3232 is no communication between ecm and intake nox sensor on the J1939 network. If you replaced the sensor with a known good one then maybe you have a problem with the harness or that busted up plug (good chance that's your problem)
3714 is just a code that tells you a derate is active because the emissions system isn't operating correctly(because of the no comm)and they want you to fix it immediately.

This is straight from quickserve.......

Possible causes of this fault code include:

The aftertreatment intake NOx sensor is not receiving power from the battery supply circuit in the OEM harness. This can be caused by an open circuit in the power supply wire, malfunctioned NOx sensor fuse, or low voltage supplied by the battery.

Open return circuit on the aftertreatment intake NOx sensor circuit between the battery circuit aftertreatment intake NOx sensor.

Open or short circuit on the J1939 data link circuit between the engine ECM and aftertreatment intake NOx sensor.

Intermittent communications between the aftertreatment intake NOx sensor and the ECM on the J1939 data link

Reference the appropriate OEM wiring diagram when troubleshooting circuits that utilize wiring supplied by the OEM.

For intermittent power supply and datalink communication issues with Aftertreatment Components, it is highly recommended that the OEM Power Distribution Center fuses and relays be thoroughly checked for loose, missing or intermittent connections.
