P1174 MINI Meaning

P1174 is a condition where there is a lean fuel balance or more air than fuel ratio, the condition determining lean fuel is the O2 sensor, it’s more a condition where the O2 detected more air and the engine management cannot adapt. Check for vacuum leaks, especially at the mass air flow (MAF) sensor air duct boot.

P1174 PONTIAC Possible Causes

P1174 PONTIAC Meaning

Fuel cylinder balance diagnostics detect an imbalance in the air/fuel ratio between cylinders and cylinders in each row. The diagnostics monitor the frequency and amplitude characteristics of the pre-catalyst heated oxygen sensor (HO2S) signal by calculating an accumulated voltage over a predetermined sampling period. An imbalance is indicated when multiple samples of the accumulated voltage are consistently higher than the desired value.

Possible Symptoms

• Check engine light on (or service engine soon warning light)

P1174 VOLVO Meaning

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

P1175 Possible Causes
