Code P1155 Engine Check

[Dyllen]

RX300 - VSC and Engine Check Lights On at the same time, try to reset but cannot, remove the EFI fuse, but still the same. Checked and found out Code P1155 Air/Fuel Ratio Sensor Heater Circuit Malfunction the mechanics said its the air flow sensor defective, is it true? try to check and install new flow sensor, but the VSC lights still on also the check engine lights. suggest by the mechanics, its the O2 sensor, 2 nos. have to be replaced. anyone can help to solve my problem, is it true to replace the O2 sensor.
