The fuel cylinder balancing diagnostic detects an imbalance in the air/fuel ratio between cylinders and cylinders in each row. The diagnostic monitors 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.

P1174 ACURA Meaning

The air/fuel ratio (A/F) sensor 1 is installed in the exhaust system and detects the oxygen content in the exhaust gases. The A/F sensor sends the output voltage to the engine control module (ECM). A heating element for the sensor element is built into the A/F sensor (sensor 1). It is activated and heats the sensor to stabilize and speed up the detection of oxygen content by controlling the current flowing through the heater. An increase in current stabilizes when the voltage applied to the element electrode reaches a certain range because the amount of oxygen that is routed through the diffusion layer is limited. The current amperage is proportional to the oxygen content in the exhaust gases, so the air/fuel ratio is detected by measuring the current amperage. The ECM compares a set target air/fuel ratio with the detected air/fuel ratio and controls the fuel injection timing.
If the A/F sensor (sensor 1) voltage is low, the air/fuel ratio is lean and the ECM uses A/F feedback control to issue a Rich command. If the A/F sensor (sensor 1) voltage is high, the air/fuel ratio is rich and the ECM uses A/F feedback control to issue a Lean command.

P1174 BMW Meaning

P1175 is a condition where there is a lean fuel balance or more air than fuel ratio, what determines the lean fuel condition 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, particularly at the mass air flow (MAF) sensor air duct boot.
