Hey guys just wondering if anybody knows any fellow Cadillac techs out there. I'm trying to change a 02 sensor on a 06 Cadillac cts v6 3.2 drivers side pre cat 02 sensor. I can get the 02 sensor out of the exhaust but cant get the connector unplugged from behind the engine. Just wondering if anybody has any tips or tricks to get it unplugged. It looks like the upper intake has to come off but I don't want to do that if i don't have too. Thanks everybody

Ive taken off the ac bracket on the upper strut tower and the brake booster hose but no luck.

It probably has a fancy button or lever to pop out of the way..

Also this should be posted in the "other cars" forum. Just because thats how it goes here lol


Have a nice day.

yea, well the biggest problem is the access. I can get one finger on it to touch it but cant get the connector undone and if I get it undone I'm worrying about getting the new one plugged in. Yea Sorry I forgot to put it in the other cars forum if someone could please move it or just disregard my mistake. thanks
