Doesn't DTC p0171 also apply to the 2002 Prius?

Question

Are there any multi-meter tests I can perform.  Do you know where I can find them on the web?

Thank you.

P0171 Fuel trim lean Bank 1

Yes this code does apply to your vehicle, this is a condition of the engine, most cause for this is vacuum leaks or dirty MAF (Mass airflow) Try a MAF sensor cleaning
