Thanks for the post difflock54.

I've read through a good deal on the closed loop issue and after swapping the ECU i'm seeing CL under different driving conditions, and I'm seeing all INC monitors are now OK. Not sure if ECU was part of the problem at this point.

Looking at the tuning link chart ...

Hey guys,
I have a CL-Fault that I can't resolve and am looking for suggestions and next steps. I've read other posts but still in the dark on this one...

I'm using a Autel ms310 but see the same issue with a better Actron ($200) scanner as well, and no fault codes.

Details:
VIN YV1LS5540T1XXXXXX ...

...well that was easy. The sensor-side connectors have a channel that clips right in. I feel dumb for even asking, but it wasn't so obvious last night from underneath with a flashlight.

thanks

Is the guide the little clip on the sensor-side connector, slightly visible in the pic? The connectors with the red top (ECM side) appear to have smooth sides.

I have Bosch OEM type sensors but it's difficult to get in there for a closer look at this point.

First off, hello, and thanks for this site! It's been a great resource.

I'm replacing O2 sensors and see my connectors (the ones with red top) are just dangling there. Looking at other photos on the nets, like the one attached, they appear to be mounted/attached on one side to the metal bracket ...
