2.5.3.8. Fuel system

Excessive impoverishment of fuel mix (P0171)

The PCM block controls values of short-term correction of supply of fuel (SHRTFT) and long correction of supply of fuel (LONGFT) at regulation of supply of fuel on the closed contour. If correction of supply of fuel exceeds previously programmed value, the PCM block decides that fuel mix too poor.

Excessive enrichment of fuel mix (P0172)
