With the car at idle and the battery light on tell me what the voltage is at the battery?Sounds like a alternator going bad. Some die slow and some go suddenly.

The voltage when the car at idle and the battery light is on is 14.7 volt. The guy at oreilly is used to be a mecanic he checked the alternator and the battery. He told me the alternator is good he tested it under load headlight on and I gave him the battery he put it in the charger for 10 minutes he said the battery is holding the charge

Hi,
about two days ago, my battery light went on when I was on an incline. I went to my mechanic who tested the battery and said it was charged. We turned the car on and off a few times and nothing. Then the battery light went on again later that night. I rinsed off some of the corrosion on the battery with water and it was fine for a day. Then, when I was going up a hill yesterday, the battery light went on again and has stayed on since - the cable connecting to the battery seems firm and only one of the cable attachments to the battery has corrosion - what should I do?

If the battery is in good condition with clean and tight posts/cables-have the alternator load tested might not be putting out or the battery is not taking the charge.

The battery light is on. Today I replaced the battery and the battery light still on.
There is a DTC code p063a generator voltage sense circuit. The alternator is generating 14.5 volt when the car is running and under load

what could be the problem
thank you

This is a very common issue on that particular vehicle. There is a T.S.B. (Technical service bulletin) pertaining to that exact issue. The t.S.B. Number is 18-007-07. It requires updating and/or reflashing the pcm. Call you local dealer and ask them about the t.S.B. Number.

I saw a service bulletin related to the p063A code as well as other code. It was listed under driveability improvements. You reflash/reprogram the computer. You may need to take it to dealership? The ref number for the bulletin is 18-007-07.

Hi:
If the alt light is coming on from time to time, I say the alt is the problem. When it was checked, was the light on?

You need to have it checked when the light is on. My guess is that it's going bad.

Chances are the alt is on its way out. However, when you have it checked, it is working fine. I would think it will progressively get worse to a point that they will be able to identify the problem.
