P1135 A/F sensor heater circuit malfunction Bank 1 Sensor 1
P1155 A/F sensor heater circuit malfunction Bank 2 Sensor 1
These 02 sensor are the upstream 02 sensor which is in front of the catalytic convertor, when you set both these codes together check the A/F heater circuit fuse which is located in the engine fuse /relay box listed as A/F heater which is a 25 amp fuse
