What sensor is Voyager using to measure "temperature" here?

It seems they use several tools - inferring from the descriptions, they can measure and compare the data when it gets back here to determine simple things like temps.

Is it possible that one of the sensors failed, thus giving the impression of a sudden change in value?

TFA states that Voyager 1 and Voyager 2 found the same thing and that the data aligns in space too.
