A bad receiver would not drain the fob battery, but a sticky/stuck button might. The TPMS sensor's have a battery, The battery can go bad and need replacement.

 

The battery can go bad and need replacement.

And by "replace the battery" it's meant "replace the TPMS sender". They're all a unit and largely interchangeable so long as you get the right operating frequency. (I don't remember which years are what frequency offhand but it can be found here with the search function.)

 

great where is my replace the TPMS sender located?

 

the other end of the valve stem inside the tire

if I understand the question

I have never tried opening up one to see the battery in the TPMS

 

no no the reciver for the tpms and keyfob box

 

the reciver for the tpms and keyfob

that's mounted on the windshield behind the rear view mirror.

 

Here's what it looks like

If yours is empty (no #1), someone removed it.

 

No, it is behind/above the mirror. bout a 4"x5"x1" plastic box attached to the windshield.

 

ooops, Steve beat me to it. If there is nothing in the box, therein lies the problem... I can't imagine the fobs would work without it... Do you have the passive entry function?

That is a different system/box

 

I have no check engine lights and there is no box in the location your describing nor is there a plug in for it in that location

 

This may sound silly, but are you sure you have a Gen 1 Volt? Post a photo.

 

This may sound silly, but are you sure you have a Gen 1 Volt?

I'm wondering the same...

 

its 2013 volt. I also just got a engine not available message. wondering if my battery's are going out.

 

I well go take a picture there is NOTHING being that NO PLUG no box no where to mount a box! dealer even told me that I dont have one

 

behind my windshield

 

OK, so the mounting bracket and TPMS/Key Fob receiver actually are there in your picture. Same as shown in post #9 and #10 above. The plug is shown plugged into the top edge of the receiver

Very confused at this point about your continued "no box" statements. Or are you saying the cover that goes over this is missing?

 

not talking about the cover. please show me what box is the tpms/key fob receiver. The picture that is posted online is a long L shaped plastic box what part of this is my rpms key fob reciver

 

please show me what box is the tpms/key fob receiver

Shown in your picture as a white-ish box with a cable plugged in. Shown in post #10 as part #1

Yours does look shorter however.

 

I don't have one of these showing in the picture

 

Interestingly... my 2011 does have the module you posted a jpg of, which also matches the screen snip Steve and I provided.

one online gm parts giant indicates that part does not fit a 2013 volt, but yet another gm part direct indicates it does fit. I suspect there may have been a mid-year model change and the hardware changed. Check the part number on the lower right module of your photo.

the gm part giant has a "show similar parts that fit my vehicle" button which brings up a module that looks somewhat more similar to what is shown in your picture.
