One problem related to check engine light on has been reported for the 2016 Chevrolet Silverado 2500. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2016 Chevrolet Silverado 2500 based on all problems reported for the 2016 Silverado 2500.
Check engine light came on throwing p203b code, which is the reductant level sensor code. This seems to have been an issue already in these vehicles dating back to 2011 when it started. I found a service bulletin #14652a regarding the replacement of such sensor but the dates on the vehicles only state 2011-2012. I want to see if there is a newer bulletin released which covers the later years with the same problem.
