A little about the car...2014 CTD with 20,642 miles. Got a CEL last week, dealer got me in today for the repair. According to the invoice, the codes were P11DB and P11DC. Write up is as follows: Circuit testing for both sensors within specification NOX sensor 2PPM -2 During vehicle operation. Concentration requirement greater than 1PPM. Test drive observing DTC report failed sensor 2. Replace NOX sensor 2. Test drove vehicle 10 miles after repair. No DTC's returned.
Drove car home from dealer, about 30 miles. Ran some errands, 20 miles later CEL is back on. Made another appointment for Monday morning. Hopefully they will be able to figure out what is causing the problem this time.
