Trying to remove the right side downstream oxygen sensor from wiring harness, but it won't give.

Can feel clip but wonder if there is a bolt that holds clip in place?

Am doing this by "feel", really can't see. Unable to get two hands on wire to undo the plug.

Any ideas?--------------Its a 2004 Discovery 2

 

Look at your new one for a visual reference. No bolt just a clip try to pull and wiggle sometimes they do get sorta seized up a little, should not be a total nightmare job though. What o2 are you using? Are you replacing all or one or what?

 

The rear sensors, I think you have to slide them off their mounting tab before you unplug them. The fronts can be unplugged still attached to the mount.

 

Its a Bosch sensor bought from Amazon. Only replacing right side downstream.

 

Okay, usually when you replace o2s you do the pair both down stream or both up stream. Anyway did you make any progress with getting it unplugged? And what was the reason for the change? What code were you getting?
