Fuel Trim Learn

The scan tool displays NO or YES. When conditions are appropriate for enabling long term FT corrections, FUEL TRIM LEARN will display yes. This indicates that the long term FT is responding to short term fuel trim. If the fuel trim learn displays NO, long term FT will not respond to changes in short term FT.
