I'm getting a B1328 Code


Recommended Posts

and my DIC shows constant 15 - 15.2 Volts - even after driving quite a while. Car cranks and runs fine, and I checked the battery cables and they are clean and no evidence of corrosion. Anyone have a clue what would make the battery voltage so high?

Nothing to be concerned about; setting an occasional B1328 during cold weather is not unusual. Key word = occasional.

Make a note to monitor your system voltage in July and August; you should see a difference.

There are many variables in the whole system voltage equation. Temperature is only one of them.


Drive your car.

Use your cell phone.
