B1952 EVDC DTC

Hello all,

I keep getting this B1952 EVDC error from the climate control module in my 2013 California 30. EVDC is for the variable displacement a/c compressor.

The climate controls all seem to work fine. When scanning with either my Thinkdiag or my Autel IM508, I also see in live data the evap sensor reading -25F. I can't find an evap sensor anywhere in any parts diagrams. In the 458 diagrams the 2 "air quality" sensors for left and right in the front of the dashboard behind the radio are labeled evap sensors. Changed those to no avail when I removed the top dash cover to be reupholstered.

In the Autel I can vary the PWM signal and toggle the compressor and all seems to be ok.

It would also be great to find a wiring diagram if anyone knows where....

Thanks for any help.
