TSB 26-2091

This bulletin supersedes 26-2045. Reason for update: update the labor operation allowances and the service procedure to include the required modules to program for F-150 Powerboost variant. Some of the vehicles listed in the Model statement above may exhibit an illuminated MIL with DTC P2C90 stored in the powertrain control module (PCM). This may be due to the software in the PCM.
