A few days ago, someone posted a diagram of the O2 sensor location which illustrates whether you have California or Federal Emissions by either having 2 or 4 sensors. I'm currently getting the Proxy Error message, so I was wondering if anyone has or can post the link for that diagram.
Thanks in advance,

I have one of the o2 sensor TSBs and to check if your car is Cali or Fed emissions you can check the emissions certification on the underside of the hood. The sticker is somewhat centered and a little more than half way back on the hood(according to TSB diagram). It says if there is no mention of the word California on the label then it is Fed emissions.

 

Cool...thanks man. I appreciate it.
