    O2 sensor 2 is the secondary O2 sensor, listed as number 16 in this diagram

    crv_exhaust.

    "P0141 - O2 Bank 1 Sensor 2 Heater Circuit Malfunction Bank" You need to get the wiring checked out to the O2 sensor.

    If this OK and you have also checked fuses, then most likely the O2 sensor will need replacing.
