It also involves the cleaning or replacement of the Exhaust Gas Temperature (EGT) Sensor 1/2 and/or Catalyst Temperature Sensor if necessary depending on Diagnostic Trouble Codes (DTCs) that may have set. A small number of customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the Technician may find one or more of the following Diagnostic Trouble Code(s) may have been set: ? 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. ? P0420-00 - Catalyst Efficiency (Bank 1). ? P1297-00 - EGR Slow Response - Decreasing Flow. ? P208B-00 - Reductant Pump 1 Control Performance. ? P0087-00 - Fuel Rail Pressure Too Low. ? P20EE-00 - SCR NOX Catalyst Efficiency Below Threshold Bank 1. ? P225C-00 - NOX Sensor Performance - Signal Stuck High Bank 1 Sensor 1. ? P225D-00 - NOX Sensor 1/1 Performance - Signal Stuck Low. ? P1289-00 - NOX Sensor 1/2 Zero Offset Too Low. ? P1296-00 - EGR Slow Response - Increasing Flow. ? P2BA9-00 - NOX Exceedence - Insufficient Reagent Quality. ? P2080-00 - Exhaust Gas Temperature Sensor Circuit Performance. ?
