Connector ID
2007 GL450, 200K miles. Engine's cut out and gone into limp mode a couple of times, and suspect the cause might be oil leaking into the connector shown in the photo.

You could unplug it entirely and all that would happen is you'd get a check engine light. That sensor is only for monitoring the catalyst health.
Next time it goes limp, pull the DTCs.
