Oil Temp not displaying CEL
The other day my CEL came on while driving to work. The oil temperature was normal but didnt seem to move fast (usually blinks between 2 temps)
Code is p0939- Hydraulic Oil Temperature Sensor Circuit Low. Now it will not display temperature at all. Car runs just fine but I have only driven it once since then. I will be taking it in but I am curious if others have seen this and if its just a new sensor needed.
