Question

2002 Lexus RX300 changed the p1135 sensor b1 s1 engine light still on

Answer 1

Hi there

The light will remain on until the car runs a self test on the O2 sensors. If you cleared the code and the light came back on, then you should check the O2 sensor fuses under the hood and also check the wiring to the sensor.
