Asked by Paddy Apr 07, 2016 at 10:29 AM about the 1999 Lexus ES 300 FWD

Question type: Maintenance & Repair

Code P1133 has been coming back for over 6 months now.  I purchased what they told me was an OEM 02 Sensor.  I have 3 total for the one that is at the front of the motor near radiator, in exhaust pipe.  When I go back to the original sensor, the car runs rough, and codes rather quickly.  I've heard I should by the Bosch 02 sensor, or get one from Toyota.  Any help would be appreciated immensely.

Bro I had the same problem and I took both exaust manifolds off and the front one near the radiator had a crack in it by the o2 sensor after welding it up and replacing the 02 sensor it went away
