P0171 System Too Lean Diagnostic Aids

WARNING: This page is about a different variant/trim than selected.
NOTE: If the system is lean at certain conditions, then the LONGFT PID would be a positive value at those conditions, indicating that increased fuel is needed.

The ability to identify the type of lean condition causing the concern can be crucial to a correct diagnosis.
