HO2S wiring
 

Do the oxygen sensors in our cars share a common fuse for the heaters? If so, where the heck is the fuse. I'm throwing codes for both heater circuits on my CLS6. Does anyone have a .pdf of the FSM for our cars?

It shouldn't be too different from the 2G TL manual. I don't want to spread misinformation so I won't upload a picture here, but for the TL I found it to be fuse 6 in the fusebox under the drivers side.

It could be different for the CL, but worth taking that information into thought and taking another look there.
