I need to replace the oxygen sensor. Its the one against the firewall. The problem is I'm having trouble finding a replacement that doesn't cost $300 from Lexus. The Denso replacement, 234-1055, will fit the front, but not the rear, because the connectors are different. Does anyone have any suggestions?

 

what does the connector look like? you can always cut and resplice the connector you need to the new 02. thats what I did on mine

 

You mean solder and shrink wrap? I was trying not do that, but it looks like this may be my only logical choice.

 

yup, thats what I did

 

Let you know what happens
