Sensor 1 is the sensor located before the catalytic converter and bank 1 is the side of the engine with cylinder #1 so if i'm correct and you have a V-6 that would be the rear of the engine by firewall and the sensor would be in the exhaust manifold

99 lexus GS-400 P420, where is the O2 sensor? Need Pics not words


Below is a picture of the location of both O2 sensors for your vehicle. Also the last picture is your evap. system. In the "dotted lined" area I would check for rotten or lose hoses in that area as well the vapor pressure sensor could be faulty as well. Hope this helps.

How to replace oxygen sensor?


The sensor is located in the exhaust system just off the exhaust manifold in the head pipe, it is removed using a special 7/8" O2 sensor socket, this socket requires a 1/2" drive ratchet and a short extension in most cases. The sensor unscrews counter clockwise. This engine will have 2 sensors, one for each bank of engine cylinders, you must id the correct sensor before the change out. If money is not a problem i would suggest you replace both sensors as an old and new sensor can provide confusing output data to the powertrain control module(computer).

bank 1 is the side cylinder 1 is on.sensor 1 is the first sensor in the exhaust on that bank from the manifold.cylinder 1 is the most forward cylinder on the motor when you look across the motor at the front of it to see which head/vlave cover is farthest forward.
