2013 Ram 3500 Check Engine Light Codes

In Denver, owners of the 2013 Ram 3500 commonly see codes like P0300 (random/multiple misfires), P0420 (catalyst efficiency), P0171 (system too lean), P0455 (large EVAP leak), and P0128 (coolant thermostat). Each code points to a different risk: misfires can quickly damage pistons or catalytic converters; an unchecked P0420 may require a costly converter replacement (often $1,000–$2,500); lean conditions increase combustion temperatures and reduce engine life; evap leaks can lead to failed emissions tests.
