O2 sensor fault codes

[Jager]

Use your Durametric to look at the O2 sensors ahead of Catalytic converters, with the Air Pump not running, you should have alternating voltage readings between 0 and .8 volts. You can compare bank 1 and bank 2.

I dont have a code tool, but i had the check engine light come on,so I went to autozone and I was told it was an O2 fault, it was reset but came back a while later, how many O2 sensors does my 99 boxster have? (2)? Thanks in advance.

Four, one in front of the catalytic converter and one behind the catalytic converter for each bank (bank 1 and bank 2).
