I do know there have been many problems with non-Denso sensors when used in the RX but this is the first I have heard of a Walker being used. It may be a fine compatible sensor. Usually Bosch is the culprit. I would politely call oxygensensors and explain the problem and the codes and the discussion here and see what they say. I wouldn't expect much but you never know. If they say they can't do anything, ask them what if you go out and buy a Denso from another source and it fixes the problem, what then?? Please do post back and let us know what the outcome is.
Don't forget to check the fuse I mentioned above. Meetya had a P0125 problem a while back and it turned out to be this fuse.

Thank you mikey00, my dad is going to replace it today.. and I will let you know what happened..!...

I been trying to locate the Bank 1 sensor 1 but I can't find it... is it under the passanger side?..

mikey00

Yes, passanger side. If you slide under the car just behind the passanger side front tire and look up between the driveshaft and body you will see it. It is about even with the back of the passanger side tire. Print out the pic and take it under the car if necessary. It helps to have a set of ramps to drive up on to do this.

Thank You Guys So Much!...

I Found The Bank1 Sensor1 And Replaced It... The Cel Light Turn Off.. And I Hope It Stays That Way...

Just curious, did you buy another Walker sensor, buy a Denso, use the original removed sensor to replace the bad one, or what?

LadyRX300

I used the same Walker sensor I had order from Oxygensensors.com and placed it in the right place (B1S1).. and placed the original removed sensor (B2S1). and it worked...
