battery temperature sensor
 

hello friends who know chrysler voyager has a sensor that measures the temperature under the battery in my car my car was missing from this picture of the temperature sensor or is there any number of friends?

Can't quite understand your posting, but the battery temp. sensor is located under the battery in GVs. It is a negative temp. co-efficient thermistor that enables the control micro. to up the battery charge voltage in cold weather.
Its action is not very good, because it isn't tightly coupled to the battery. Therefore engine heat will reduce its effect to zero far sooner than the battery will warm up.
