Location of O2 Sensor on Lexus IS 250
The O2 sensor in a Lexus IS 250 is located in two positions: bank 1 and bank 2. One sensor is near the firewall and in front of the catalytic converter, while the other is behind the converter closer to the rear. They should primarily be the same part, just different lengths of wiring. The bulb part is connected to the exhaust. The O2 sensor is connected to a quick-disc.
So, in summary, the O2 sensors in a Lexus IS 250 are located in two positions: one near the firewall and in front of the catalytic converter, and the other behind the converter closer to the rear. They are primarily the same part, with different lengths of wiring.
