Flash: 6.7L Diagnostic And System Improvements This bulletin involves reprogramming the Engine Control Module/Powertrain Control Module (ECM/PCM) with the latest available software. A small number of customers may experience a Malfunction Indicator Lamp (MIL) Illumination. Upon further investigation, a technician may find one or more of the following Diagnostic Trouble Codes (DTCs) set in the PCM memory. ? P2281 - Air Leak Between MAF And Throttle Body. ? P1477 - Intake Air Diverter Valve Position Sensor Circuit Shorted To Ground. ? U3017 - Control Module Timer/Clock Performance. ? U110E - Lost Ambient Temperature Message. ? P0087 - Fuel Rail Pressure Too Low. ? P2281 - Air Leak Between MAF And Throttle Body. ? P0544 - Exhaust Gas Temperature Sensor Circuit - Sensor 1/1. ? P0128 - Thermostat Rationality. In cold ambient temperatures. ? P214D - SCR NOx Catalyst Outlet Temperature Too High During Particulate Filter Regeneration. ? P24A5 - EGR Cooler Bypass Bank 1 Control Stuck. ? P040B - Exhaust Gas Recirculation Temperature Sensor ?A? Circuit Performance. ? U1421 - Implausible Ignition Key Off Time Received. ? P0420 - Catalyst Efficiency Below Threshold. ? P026B - Injection Timing Performance. ? P04DB - Crankcase Ventilation System Disconnected. ? P1C55 - NOx Sensor Intermittent - Bank 1 Sensor 1. ?
