Just interested if anyone of the Priuschat expertise can explain to me; My 2007 gen2 has generally a high value (40-60%) for idle Calculated Load. My 2005 has a value of 20% - and it’s almost identical to the Engine Load value, while the 2007 value diverts atleast +100% from the engine load value. The 2007 engine runs great and LTFT are within 2% and the MAF shows the same values under the same scenarios. The MAF sensors are refreshed/cleaned - and when they are switched between the g2 vehicles it shows the same abnormality for the 2007. Throttle body clean and fresh, same effect after reset of learned values. What else is involved for this value? When I added a used MAF sensor (they have maaaaany OE numbers for many different vehicles…) it showed the same values. For knowledge
Calculated load was originally "current airflow divided by peak airflow"(with BARO correction). Google says that the car makers used different implementations of this, so the government changed the calculations to be more "defined" (ie, more corrections & restrictions). That might have happened between 2005 & 2007. Absolute load is "current air mass divided by theoretical max air mass for the RPM" - it's a rough indication of Volumetric Efficiency. Personally, I don't pay much attention to those PIDs when looking at the data for diagnostics. Posted via the PriusChat mobile app.
