Lexus is lambda sensor!

Question

Hello, i need to change O2 B1S2, because of P0141 fault for my Lexus IS200 (1G-FE), Where is it exactly, would like to see on a diagram there's 2 O2 sensors under the car, which is it?

Answer 1

HI there

This is the sensor AFTER the catalytic converter under the car. So, look at the exhaust and make sure there is one before the converter and one after. The one after is always sensor 2.
