babybaluga32 Posted May 10, 2011 Share Posted May 10, 2011 front is 3 pin rear is 4 pin square ( on a 2.2) Link to comment Share on other sites More sharing options...
johnegg Posted May 10, 2011 Share Posted May 10, 2011 front is 3 pin rear is 4 pin square ( on a 2.2) this is correct. however, the o2 sensors are the same front and rear, they both have 3 wires. just the connectors are different. go figure!!!! in others years, 00 - 04 this may not be accurate.

vicdeng Posted May 10, 2011 Author Share Posted May 10, 2011 thanks guys. Very appreciate it. Is there anyone here that experience the Denso and Bosch sensor from Rockauto? Link to comment Share on other sites More sharing options...
Lojasmo Posted May 10, 2011 Share Posted May 10, 2011 Redacted unhelpful, smart-ass answer. Edit: Bosch makes a good product. Likely, either will outlast the car. Link to comment Share on other sites More sharing options...
mwiener2 Posted May 10, 2011 Share Posted May 10, 2011 Likely, either will outlast the car. no it won't or he wouldn't be replacing one. They average about 80k in my experience.

vicdeng Posted May 11, 2011 Author Share Posted May 11, 2011 well, hopefully, it will. My car has 168k on it, but the engine only has 30k on it...I want it to run as long as it can. Thanks guys. I think either Denso or Bosch will do the job. Thanks again for all the comments. Link to comment Share on other sites More sharing options...
stiwanabe Posted June 2, 2011 Share Posted June 2, 2011 is this a common subaru specific thing? Because I work on GMs all day and if you get a P0420 only its 99.99999999% of the time a bad converter. We don't even waste time trying to diagnose it, we just replace the converter. If you have a bad o2 sensor you should be getting some codes in the range of p0130-p0139. It helps to have a proper scan tool. If your #1 o2 sensor is switching voltage properly in closed loop the #2 sensor should show a steady reading and not fluctuate like #1. When #2 is doing the same thing as #1 you have a bad cat. Link to comment Share on other sites More sharing options...
Zues Marine Posted June 2, 2011 Share Posted June 2, 2011 ^ po102 is almost always o2 in subarus, especially with aftermarket cats and or headers Link to comment Share on other sites More sharing options...
stiwanabe Posted June 2, 2011 Share Posted June 2, 2011 ^ po102 is almost always o2 in subarus, especially with aftermarket cats and or headersyou mean p0420? p0102 is for MAF. i could understand saying the o2 sensor causing a 420 if you have aftermarket parts, but thats probably bc the sensor is doing its job by reporting low catalyst effeciency. Thats not to say that on a stock system with a 420 its automatically a bad sensor. Link to comment Share on other sites More sharing options...
