Calculate load

on the the scanner, my calculate load is at 32.1% does this indicate a possible problem with fuel injectors?

 

Calculated load references a few tables and some maths on the ECU. when it states 32.1% what are you doing?

 

it's at idle

 

Calculated load is just that, the PCM calculates engine load.
It is based largely off Mass Airflow, Throttle Position, and Engine RPM.
It doesn't really tell you much, it just kinda tells you how hard the engine is working at a given RPM.
Smaller engines will naturally have a higher calculated load at idle than larger engines.

 

That's a great explanation. Makes sense to me now

 

I believe the calculated load on the toyotas is volumetric air load. Meaning, @ X RPMS, you have a hypothetical MAX amount of air that the motor can be pumping based on its displacement. The Mass Airflow Sensor which is measuring incoming air load to the motor is referenced against that theoretical max and you get a percentage. This is why you will see "Load" numbers at WOT pretty high near 100% and pretty flat during the entire rev range.

 

Most of the time, calculated load is simply a combination of throttle position, mass air flow (MAF) and maybe manifold absolute pressure (MAP)

If you're worried about fuel injectors or fuel delivery just look at the fuel trims
