I am getting ready to install my A/F ratio gauge, so I was looking around and thought I found the O2 sensor today (in the top of the downpipe), but I was thrown off by the fact that it only had one wire (I'm used to the concept of 3 and 4 wire O2 sensors).

Anyway, now that I've confirmed (both on USMB and in the Haynes manual) that we do indeed have 1-wire oxygen sensors, I checked the Haynes manual and it indicates the exhaust manifold as the location of the sensor. So is the sensor in the top of the downpipe an O2 sensor or something different? Are they perhaps in different locations for the non-turbo and turbo cars?

(BTW, I've noticed that Haynes seems to lack a little bit on specifics in this book, since they attempt to cover all 1980-1994 Subaru 1600 and 1800 cars in one book...LOL...many times items that are different about the turbo cars seems to get overlooked :rolleyes:.)

that is the o2 sensor on the downpipe. na ea82s have no downpipe, so instead it is at the intersection of the 2 pipes going into the cat.
