Today I began looking at a 2015 Crafter. I am not too familiar with these and it seems to have NOX faults. The coolant pump fault is the pump itself.
Both the NOX sensor and heating module have power and ground connections. If anyone has any suggestions they would be greatly appreciated and give me something to work off.

nox sensors seem to be giving a lot of problems ,possible faulty sensor, can you do a resistance on the sensor
