The service engine soon light just came on and I had it scanned the code was p0138 and I have been told its the o2 sensor before the cat.I need to know where the sensor is located so i can replace it.Also does anyone know the wire configuration because i bought the 60 dollar universal instead of the 400 dollar one.

 

I Dont For The Rear . I Ththink They Make A Univeral O2 Sensor But Only For The Front O2

 

are you running a test pipe or cat elimator pipe?

 

It's the rear sensor (Bank 1 Sensor 2) you got the wrong one. Don't just replace it look at the old one first might just be a wire melted to the pipe.

 

There is a post on here that explains how to use spark plug non-foulers. This is what I did when I put my test pipe on the car. It got rid of the SES light and it has not returned.
