Original wording in English

Flash: 3.0L Powertrain Diagnostic And System Enhancements This bulletin involves reprogramming the Powertrain Control Module (PCM) with the latest available software. 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. ?

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
