P0032 H02S heater control circuit high (bank 1 sensor 1 )
Bank 1 sensor 1 is upstream 02 sensor so this make it a engine management 02 sensor,Thie first is to inspect the harness, circuit high out mean its disconnected this can be internal of the 02 sensor itsef to the harness, If you decide to replace the 02 sensor what is required is a 02 socket and a good ratchet, disconnect the 02 sensor connection remove with the socket and install the new 02 sensor, reconnect the harness clear the code, Retest.The 02 is number 1 in diagram,
