Volvo engine code DTC P054F
Idle Engine Speed: Idle Engine Fuel Rationality Fuel Rationality Low: Nominal idle fuel rate (based on engineering analysis) can be as low as 10mm3/stroke and as high as 100mm3/stroke due to various installation differences and activations of various features (AC, air compressor, alternator etc). Diagnostics is set up to detect 50% lower than the lowest possible idle fuel rates. When engine is in idle governor mode (or fuel limiter mode) if the required fueling is below limit idle fuel low fault code is logged. Fuel Rationality High: Nominal idle fuel rate (based on engineering analysis) can be as low as 10mm3/stroke and as high as 100mm3/stroke due to various installation differences and activations of various features (AC, air compressor, alternator etc). Diagnostics is set up to detect 50% higher than the highest possible and 50% lower than lowest possible idle fuel rates. When engine is in idle governor mode (or fuel limiter mode) if the required fueling is above limit idle fuel high fault code is logged.
