Cylinder 12 Fuel Injector A Offset Learning At Min Limit
The injector-offset learning routine for fuel injector A on cylinder 12 has driven its correction value to the minimum allowed limit and cannot trim further. This indicates the injector flows significantly less than the calibrated reference - typically due to drift, partial blockage or wiring resistance.
