Question about 2000 Lexus RX 300
Check the wiring to sensor 1 bank sensor 1 for possible damage from the exhaust, also make sure the connector to the O2 sensor (they called it a air/fuel sensor, incorrect) is in good condition and not contaminated with oil or water intrusion into the sensor, look for corrosion on the pins, (green or white residue) since all the these codes are for the bank one sensor, if u find nothing else wrong then it is safe to say the sensor is defective, bank 1 sensor is the engine cylinder bank where # 1 spark plug is located, the sensor is before the catalytic converter, this is the rear cylinder bank as u stand in front of the car. see photo diagram.
