Code C159E, air pump temperature sensor fault

[Tom Robinson]

2018 3500 diesel dually with rear air suspension. I have searched for this on the forum and on the web to no avail. The "service air suspension" alert has popped up intermittently for the last year or so and always when temps were in the 60's. Now, it is coming up much more often and I finally have a code that states the air pump temp sensor is either shorted or open. I've looked at the pump and only see one connector and nothing that looks like a temperature sensor. Anyone else had this or know where this sensor is?

Did you end up solving this issue? Mine did this yesterday a few days ago but the code went away I hit the alternate ride height button.
