Asked by Mar 03, 2016 at 12:08 PM about the 1999 Lexus ES 300 Base

Question type: Maintenance & Repair

I get a P420 code along with the P1133 code for 99 Lexus ES300, I've changed O2 Sensor under motor towards firewall, and the 02 Sensor on front of engine by radiator.  I used aftermarket sensors, and is that my problem.  Not sure what the P420 means.  Thanks for any help

P1133 bank one sensor one and a P420 are still after you cleared the codes and ran a relearn protocol would tell me that there is a failure in the catalyst on bank one. You must clear the codes after the repair and not run another unless the check light turns on or the relearn protocols have been accomplished. Did you so that?
