          a digital meter [D] to the measuring adapter

    Oxygen Sensor Output Voltage
      Connections to Adapter:
       Digital Meter (+) → R (sensor BL) lead
       Digital Meter (–) → BK (sensor W) lead

• Measure     the output voltage with the engine stopped and
  with the connector joined.
• Turn   the ignition switch on.
  If the reading is DC 5 V or more, repair or replace the main
    harness.
    If the main harness is no problem, replace the oxygen
