Fuel Trim Learn

Scan Tool Displays NO or YES. When conditions are appropriate for enabling long-term fuel trim corrections, FUEL TRIM LEARN will display YES. This indicates that the long term fuel trim is responding to short-term fuel trim. If the Fuel Trim Learn displays NO, long-term fuel trim will not respond to changes in short-term fuel trim.
