battery temp sensor?

[timelessconstructionllc]

I'm showing code p0514. It says battery temp sensor circuit range/performance. Anybody have any clue what this means. Thanks in advance.

Underneath the passenger battery is a temp sensor for the batteries... its so that the ECM can correctly charge the batteries based on outside temperature and the temperature of the batteries... I'm going to assume that this circuit is faulty or the senor is faulty and it can't read temperature. .

Yep, but its under the drivers side battery. If you pull the fender liner you can see it.

Is this something I have to get from the dealer? Anyone know how much the parts cost?

Wait! Don't do anything at all. Wait awhile (5 restarts, at least) and see if the problem goes away.

This is a well documented "bug". See, the battery sensor is looking for a change in battery temperature over time. If it doesn't see that, it trips P0514.

It's not uncommon for this to happen in cold weather if the wind is blowing just right. The atmosphere cools the battery as it charges, and the sensor complains.

I've had it happen to me a few times over the years. Every time it's a one-time fault detection that resets itself after 5 or so restarts.

I've gotten it quite a few times. I have always ignored it.

Thanks rbattelle. Sure enough, it took right about 5 restarts and it was gone.

A friend with a Smarty can do it for free if the dealership wont.

Ah64id- Thank you. That good to know. I'm wanting to get a Smarty in a few months. I had no idea they could fix problems Like that.

Smarty uses the most current OEM software, so it updates your ECM with any flashes like that.
