A lovely story about O2 sensors

[phaphaphooey]

I got a lovely Cel telling me that one of my precat O2 sensors was on its way out so I tested both of the precat sensors per Loren's instructions (the whole testing the Ohm's routine) and ordered a new one. When it got in, I tested it also to see what readings a new one would generate. Numbers looked great so I popped it in and promptly got a Cel this time telling me that both precat O2's were dead. I knew this couldn't be since one of them was brand new so I pulled them off to have another look. It seems as though I damaged the connectors when I inserted the multimeter probes to test their resistence. I was as gentle as possible but perhaps my multimeter probes are bigger than some others. Who knows. Anyways I can see that the metal contact points inside the plug are far enough apart now that they do not make contact with the metal blades of the connector on the car that they plug into. This explains why it isn't getting a signal from either of my precat O2's.

So, with that said, anyone have any ideas? I hate to buy 2 new O2 sensors when I only need the plugs. Anyone know if Porsche sells the O2 sensor plug seperately from the sensor itself? Any other sources that might? I hate the idea of dropping $300 on sensors when all I need are the plugs. Any input is totally welcome at this point.

Do the 'lugs' on the connector not back out?? Normally there is a 'back plate' which you can remove, then using a needle or paper clip or somthing locate the 'tab' that holds the 'lug' in, lift or press and back it out. When out close up the 'lug'. All Automotive plugs tend to be similar to this?? Maybe a photo on here could help?? Dave.

What codes told you that both sensors were dead? Very unlikey.

Unless the oxygen sensors' internal heaters are in series.....

I have no clue about this stuff. I am buying some used O2 sensors off a board member and salvaging the plugs from the old sensors.
