This article supersedes TSB 13-5-20 to update the Service Procedure.
Some 2012 F-Super Duty Chassis Cab F-450 and F-550 vehicles equipped with a 6.7L diesel engine may exhibit an illuminated MIL and DTC P207F with or without DTC P204F. This condition may be most common with vehicles operated in low-speed driving conditions and/or when operated in stationary idle mode for extended periods of time preventing the vehicle from fully completing the exhaust regeneration process.
Follow the Service Procedure steps to correct the condition.
- Print the customer information sheet at the bottom of this article and provide it to the customer for awareness. (Figure 1)
- Using an Integrated Diagnostic System (IDS) or equivalent, check for DTCs. Is DTC P207F present with or without DTC P204F and no other DTCs?
- No – this article does not apply. Refer to Powertrain Control/Emissions Diagnosis (PC/ED) Manual for normal diagnostics.
- Yes – proceed to Step 3.
- Reprogram the powertrain control module (PCM) to the latest calibration using IDS release 85.01 and higher. Calibration files may also be obtained at www.motorcraft.com.
- Is the vehicle in a forced idle mode after reprogramming?
- No – repair is complete.
- Yes – the vehicle is in forced idle mode after the calibration has successfully updated. Perform the following procedure to return the vehicle to normal operation.
- Start the engine.
- Keep the vehicle in Park.
- Increase the engine RPM to 1,800.
- Using the IDS scan tool and monitor PIDs EGT_11, EGT_12, EGT_13 and EGT_14.
- Once all 4 EGT PIDs display 110° Celsius (230° Fahrenheit) or greater, return the engine RPM to idle.
- Allow the vehicle to idle for 10 minutes.
