You need to read the FSM. I keep saying this, but no-one listens...

For error codes 8 (airflow sensor) and 10 (air temp sensor) read page F1-23 in the NA Fuel & Emissions chapter. Check the AFM is plugged in properly first, since it's unlikely both sensors would fail together.

Error code 20 is for the OMP position sensor, not the AFM, and this is the one that'll be putting the ECU in limp mode. Read page D-16 in the Lubrication System chapter.
