    Error CODEs p1166 and P1167 on Honda CRV
    I have a 2002 honda CRV, has 67K miles on it. Got it scanned on Autozone, and got P1166 and P1177 error codes. After research, found the description of the codes:
    P1166 Air/Fuel Ratio (A/F) Sensor (Sensor 1) Heater System Electrical Problem
    P1166 Heated Oxgen Sensor Sensor1 (Primary HO2S) Heater Circuit Malfunction
    P1167 Air/Fuel Ratio (A/F) Sensor (Sensor 1) Heater System Malfunction
    P1167 Heated Oxygen Sensor Sensor1 (Primary LAF HO2S) Heater System Malfunction

    Now, what is the best way and less expensive way to fix it. Your info would be great help. Thanks.
