Has anyone dealt with the battery temp sensor? Can it be tested? 06 T&C 3.8L with random loss of battery voltage. Battery, alt, starter all pass two different parts stores tests. Dont want to waste time or $ on unneeded parts!

 

Well , if thats the case.....Look elsewhere from Battery Temp sensor. As the name implies, It measures the ambient temperature of the Battery and feeds this information to PCM....where your voltage regulator uses it to protect from overcharging a cold battery. A failure in this sensor would set a DTC and Check engine lamp, and would default to 65 degrees F., which WILL NOT CAUSE A LOSS OF VOLTAGE.

Now.....As I have asked before in other threads.....DO you buy Meat from the plumber??? Does the butcher come over to fix your leaky Toilet? ..Of course not...So why are you letting a salesman fix your car??? Parts stores offer these services to "SELL PARTS", and most of the "SCAN" and "BATTERY" boys are not competent enough to tie their shoes.

Bring the car to a COMPETENT mechanic, and ask for a PARASITIC LOAD TEST. If they dont understand..try again somewhere else.

 

i also have this problem but Chrysler dealer in Monaghan Ireland dos not know what it is and its not showing up on the Chrysler software that this dealer has can any one help me its coming up as Battery Temperature Sensor Circuit Range Performance

 

take the battery out and have a look at the sensor,make sure it clean and the wire is complete,not broken bla bla... make sure it high enough that the battery is sitting on it,,,little springy

u cant miss sensor,round silver thing bottom of tray
