[hypoxia]

I unplugged the NOx sensor, sprayed the connections with electronic cleaner. Started the day in traffic, the Hot Exhaust light illuminated at one light. It extinguished as soon as I started moving. The computer had the code but I think it has to happen 2 or 3 times before the check engine light illuminates.

I ordered the Inlet NOx Sensor, should arrive tomorrow. Cummins is proud of them at One Newell Unit. Fingers crossed! Holiday weekends seem to be when things happen.
