Toyota Previa Check Engine Light On!

[hellgrace]

Hi!

Check engine light was on for month and finally I got time to take it for a scan.

Result came and show :

P0161 O2 sensor Heater Circuit Malfunction(Bank 2 sensor 2)

P1135 A/F Sense Circuit Heater Malfunction(Bank 1 sensor 1)

Engine is 2AZ-FE with total 2x O2 sensor(top) and 2x A/F Sensor(below)

Model is ACR-30R 8 seater.

Exactly which one is faulty? I am confused with the "Bank 2" since I am running with 4 Cylinder engine not the V6 one.

Thanks!
