Confirm that the display of "O2S B1 S2" and "O2S B2 S2" changes between 0 to 1 V with the engine speed at 2,500 rpm.
The voltage output oscillates more than 8 times in 10 seconds.

NOTE:
-

Perform the check immediately after warming the engine up.

-

If the voltage variation could not be verified, warm up the A/F sensor again. If it could not be verified even after warming up the sensor
again, check for DTCs.
