Hello,
i was wondering if it is ok to move my car from the back yard to the driveway with the oxygen sensor taken out?

 

No problem as long as the car runs. It is a emission part that will throw a code on SES light.

 

ok, yeah the car runs, i just want to be able to get under the car to install the new oxygen sensor.

Thanks for the info

 

Just replaced my O2 sensor and the Chiltons specifies conductive anti-seize.
I used Permatex Copper anti seize because it says it OK for o2 sensors but called permatex anyway.There technician said it is conductive. First time I have heard that. Anyone else heard of this ?

 

Yeah first time that i heard of it to, i was just on there website some info on there. So i guess you cant use just any anti seize.

Another question when installing a new oxygen sensor how tight do it have to be?

Thanks

 

::Off Topic::

Last time I removed an O2 sensor, I used GM P/N 12377953 anti-seize on the threads before I re-installed it because the threads were dry. That P/N is what was specified in the GM service manual. My '87 Camaro FSM also specifies this P/N (although it's the old, superseded P/N).

The service manual stated that it is a graphite based lubricant with glass beads and that graphite burns off leaving the beads to act as the anti-seize.

I've used the regular old copper and aluminum/nickle stuff before finding out about the GM specified stuff. Can't comment on how easy/difficult it is to remove a sensor with the old copper and aluminum/nickle stuff applied.

 

If you asking about why the anti-seize has to be conductive , It's because the O2 sensor's circuit ground path is through the metal to metal contact of it being screwed into the (grounded) exhaust system . If it were insulated by the anti-seize it would interrupt the circuit and the ECM would receive no O2 sensor voltage signal . The fact that it has one wire only is the proof that it gets it's ground side from the exhaust it's screwed into .

Later sensors , like especially the heated ones , will have 4 wires , 2 of them being power and ground for the heater and 2 being ground and signal out for the sensor , with no reliance on a ground connection from where it's screwed into the exhaust ...

 

do any one know what the torque is for installing a new oxygen sensor?

 

Does anyone know how to check the O2 sensor on camaro 3th gen?

I've searched on the net and YT and found a lot of tutos but it's always for multi wires O2 sensors.

Also they say never to remove the pigtail and connector. It "could adversely affect operation". Why's that?

If we have to change the connector we'll have to unplug the connector anyway, don't we?



About the torque specification, I don't have the Chilton's manual on hand but I think you can find the torque for the O2 sensor in it.
