Had code P1130: Circuit malfunction Bank 1 Sensor 1
Replaced sensor with Universal Type Oxygen Sensor, 4 Wire, Heated, Part # OS-4000 from US AutoParts Network.
Cleared codes with code reader.
Now I get code P1155 Air/Fuel Ratio Sensor Heater Circuit Malfunction (Bank 1 Sensor 1).
Any Ideas??

Hi RLB LOE,

Apparently the "universal" O2 sensor isn't compatible with your vehicle. Toyota and Lexus use the term "air-fuel ratio sensor" for the upstream O2 sensors. I would obtain the proper sensor, install it, clear the codes, and see what happens. Oh - first make sure you didn't damage any of the wiring connected to the sensor.
