I started with my car having 3 codes
P0130
p0135
p0136

I cleaned my O2 sensor and the coders went down to
p0135

I then replaced my sensor 1 bank 1 sensor with a denso universal O2 sensor and now I only get the code
p0130

As far as I know my wiring is good I rewired it and got the say code

 

OEM sensors are alway better. I hear that people get codes with after market sensors.

 

How do i know it's OME? They had one that would have the plug i needed but it was 360 dollars.

 

Not sure but I got my from a Volvo salvage yard. I figured most people would have them replaced at the steeler and if I got one from a salvage yard it could be just a couple of years old. I paid $25 for it and it has worked fine for about 8 months now.
