    2. Turn ignition switch OFF and wait at least 10 seconds.
    3. Restart engine and keep the engine speed between 3, 500 and 4, 000 rpm for at least 1 minute under no load.
    4. Let engine idle for 1 minute.
    5. Check the voltage between ECM harness connector terminals under the following condition.
      ECM Condition Voltage
      Connector + -
      Terminal Terminal
      F11 50 (HO2S2) 59 Revving up to 3, 600 rpm under no load at least 10 times The voltage should be above 0.78 V at least once during this procedure.

      Is the inspection result normal? 

      YES: INSPECTION END
