1999 Lexus ES300 3.0L O2 voltage
Posted to Asian Driveability on 2/27/2020 9 Replies

Help me please lol. This vehicle arrived with a PO420. I used the downstream O2 signal to confirm catalyst failure. Sensor consistently switched over middle hot and at 2K RPM. We sold all converters and bank 1 AF sensor because bank 1 was at -39 total trim...
