    There are many temperatures in a Prius including two engine coolant sensors. These are the temps I monitor through obd2, in this case Car Scanner. There are others in the hvac and battery systems as well.

    2012 Prius v Five. On the P12 device, oil temperature is an available to be displayed, OBD2 value, along with other internal and ambient temperatures. I don’t the location of know its sensor origin.

    Can you screenshot that? rjparker's screenshot shows some PID information, such as to distinguish "coolant 7C0" from "coolant 7C4".

    What I'm wondering isn't limited to the location of the sensor, but extends to whether there is such a sensor, or what the P12 device is showing you as "oil temperature" instead.

    Best to inquire with the P12 folks. Brush up on your Mandarin…

    Anybody seen any other OBD device that purports to show an "oil temperature" from a 2012 Prius v Five?

    Anybody seen such a value in Techstream?
