AoA

Following is the MAF sensor reading of 1sz-fe engine on idle, engine was running with optimal temperature and in close loop.

Please suggest is it normal on idle or otherwise?

This seems about the right voltage at idle.

Have you checkef mass air flow rate at idle through obd2 device?

Yes it shows 1.9 to 2.0 g/s on idle. i guess it should be 1.6 g/s for 1000cc car.

1.5v is normal at idle.
