How do you change the oxygen sensor???
 

On a 92 300 ce.
Is it plug and play or is it more to it.
My car does not have the check engine light, so i do not have to reset that.
Thank you.:confused:

The oxygen sensor is on the exhaust pipe near the back end of the transmission. The wires go through the floor into the cabin. There's a connector under the passenger carpet possibly behind a panel board. Undo the connector, push it through the hole, remove the old oxygen sensor, install the new oxygen sensor.
