    O2 Codes

    I need to get an inspection this month and I'm throwing a few codes. Does Nelson turn off the rear O2s?

    P0135, O2 Heater Circuit Malfunction Bank1 Sen1
    P0155, O2 Heater Circuit Malfunction Bank2 Sen1
    P1133, Manufacturer Control Fuel Air Metering.

    What is the P1133. Is it going off because of the O2s? Should I replace both front O2s first?
    thanks for the help.
