I have a 2008 Subaru Legacy 2.5i. It threw a code the other day. Forgot the number, but it was one of two problems. o2 senor or catylic convertor. I want to start at the o2 sensor. I know there are 2 sensors on the car, upstream and downstream. How can I go about figuring out which sensor has the problem?
