Bank 1 refers to the bank that includes cylinder No.1. Sensor 1 refers to the sensor closer to the engine body. Sensor 2 refers to the sensor farther away from the engine body.
WIRING DIAGRAM Refer to DTC P0125 on page DI-43 for the WIRING DIAGRAM.
INSPECTION PROCEDURE HINT: Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because freeze frame records the engine conditions when the malfunction is detected, when troubleshooting it is useful for determining whether the vehicle was running or stopped, the engine warmed up or not, the air-fuel ratio lean or rich, etc. at the time of the malfunction.
