It also involves replacement of the Oxygen (O2) Sensor and cleaning or replacement of the Exhaust Gas Temperature (EGT) Sensor 1/2 if necessary depending on Diagnostic Trouble Codes (DTC) that may have set. A small number of customers may experience an intermittent engine shudder or vibration which may not set a Diagnostic Trouble Code (DTC). In addition other customers may experience a Malfunction Indicator Lamp (MIL) illumination upon which the technician may find one or more of the following DTCs have been set: ? P26AB-00 - Engine Coolant Bypass Valve Stuck. ? P24AF-00 - Particulate Matter Sensor Circuit Performance. ? P2196-00 - O2 Sensor 1/1 Stuck Rich. ? P1E0C-00 - Empty Fuel Tank. ? P2237-00 - O2 Sensor 1/1 Pump Cell Current Circuit Open. ? P1297-00 - EGR Slow Response - Decreasing Flow. ? P0420-00 - Catalyst Efficiency (Bank 1). ? P20C2-00 - Reductant Heater 3 Control Circuit Performance. ? P204F-00 - Reductant System Performance. ? P20E9-00 - Reductant Pressure Too High. ? P249C-00 - Excessive Time To Enter Closed Loop Reductant Injection Timing Control. ? P1288-00 - NOX Sensor 1/2 Zero Offset Too High. ? P2002-00 - Diesel Particulate Filter Efficiency Below Threshold. ? P2299-00 - Brake Pedal Position / Accelerator Pedal Position Incompatible. ? P241D-00 - Scr Inducement - Forced Engine Shutdown. ?
