2. Make sure that there is continuity 2.5-5.0 Ohms @ 20°C (68°F) between terminal 3 and terminal 4 on the heated oxygen sensor connector.

NOTE: If the scan tool dose not display the standard value although no abnormality is found by the above mentioned continuity test and harness check, replace the heated oxygen sensor (rear).
