Need help with P0197 code

Does anyone know under what conditions this code is triggered?

Either an open circuit or a short to ground; could be wiring, sensor itself, or the DME. You need to check the sensor for the correct resistance and continuity, and test the wiring from the sensor to the DME for a short.

Are we talking about this sensor? Would the temp reading still work if there was a short? The level readings work too.

Anyone have a wiring spec for this sensor so I know what to look for?

Thanks.
