P0100 is Mass Airflow Sensor malfunction. It may cause other codes.
Swap in a known -good MAS. Most Toyotas and Lexuses use the same MAS made by Denso. If that fixes the codes then the MAS is defective,
You can clean the MAS' sensor element with non-residual contact cleaner spray. Sometimes MAS looks good and tested good but still defective. You may need to buy a new one.
