the voltage has to be verified to the o2 sensor heater circuit. the wiring needs to be checked to see if it is not shorting anywhere.
the sensor itself needs to be ohmed out for the heater section.

lastly, the pcm has to have the ability to ground it to make the heater work.

there is a lot to the codes to check
