Battery temperature sensor

Does any one know how this stupid battery temperature sensor comes out I am looking at this and do I have to pull the battery tray out
And don't tell me it has to be in here I am sick and tired of this jeep charging 14 .5 cold but only 13.2 hot this has to be one of the dumbest things ever
also thinking it would be best to install a external voltage regulator
today in traffic with the ac on she put out only 13 volts I may old school but this is not acceptable as it wears the battery down

Re: Battery temperature sensor

Never heard of a battery temperature sensor before?

Sounds strange that the voltage is dropping that much though, mine never leaves 14V when running regardless of accessories being on/off, normally sits at 14.4V though.

Re: Battery temperature sensor

As far as i remember, you have to remove the tray to get the sensor out. Not sure if you would be able to disconnect the connector without removing the tray.
You will probably get a "Check Engine"light as soon as you disconnect the temp sensor. Also the temperature input is used to enable or disable certain OBDII faults.
The voltage of 13V is indeed a bit too low, however a fully charged battery only has 12.6V, so with 13V there is stil a (low) charging current and the battery will not be depleted, however charging will take longer.

Re: Battery temperature sensor

my think is to take the sensor out of the
battery tray and leave it hooked up and just tie wap
it away from the battery. I know what
the engineers wants but I do not agree
with their thinking
also if it not unhooked then there should be
no ck engine light to come on
so tomorrow I guess I will have to pull
the battery tray out and see if I can
get this stupit sensor out

Re: Battery temperature sensor

So you could put the sensor at an other position, but will that help? It would if the battery really was getting (too) warm. Or the sensor is not working properly, or maybe some other heat source is warming it up? The problem can be with the alternator/rectifier or even a not proper drive belt tension.
