P1174 VOLVO Meaning

The control module receives information from the heated oxygen sensor (HO2S) about the fuel/air mixture when idling at both the lower and upper part-load range. If the fuel/air mixture deviates from λ=1, the short-term fuel trim will compensate for this by adjusting the injection time so that λ=1 is achieved. When the short-term fuel trim makes an adjustment, the integrator median must be adjusted by the long-term trim. Diagnostic Trouble Code (DTC) ECM-260A is stored when the long-term trim must be adjusted to almost maximum in the upper part load area
