-Help- Check Gauge Light & Error Code P0622
 
Hello, fellow Tj Owners.

I have had this issue for around 4 months now.

Every so often My battery gauge will drop to the 1-4 mark and my check gauge light will go on. I pulled the code with the key jingle.


I have taken it into a battery store and autozone and they don't pull any codes and alternator and battery test fine. It starts like a dream every day and never hesitates.

I have no idea what to do before I take it into the stealership :(

Any help would be greatly appreciative.


I have checked all connections, cleaned all cables of dust. I have some corrosion on the cables, but that is about it. About 3 months ago I replaced the battery since the battery has been in since 2005, and put in a new stereo and want to fix this before upgrading the stereo more.

Thanks

David

I was going to help you out untill I read the "Stealership" comment.

P0622 is a charing system code involving the feild control circuits, check all the wiring and connections between the alt and PCM if their all okay check your engine ground makes sure its clean and tight from there you'll have to test your altenator output sommewhere ( pull it off and take it Autozone ) if thats okay you may have an internal pcm problem.

Or you could bring it to me to diagnose for you.....I'm here at the "stealership"

Did this start after replacing the stereo?

Honestly I am unsure if it was that or battery. It could very well be the stereo. I had a new deck and speakers installed with audio express. But it wasn't doing this with the stock battery or stereo when I bought it.

Are you in Tucson? Also taking it in to the dealership would be my last resort. I kinda didn't want to pay a fee just for looking at it.

Finally got around to try one last thing and it worked!! Cleaned the battery terminals and wires solved my issue with the code, let's hope my check gauges light will stay off as well

Bump for any more suggestions?

Its not the alternator,the battery.

Terminals is shiny as can be!

Only other thing I can think it could be is a bad wire somewhere. My ground looks and is clean. Maybe the wiring in the wiring harness to the alternator.

What colors of the cables do what that plug into the alternator.

I read that the green was a field ground?

This issue is driving me bananas! :eek:

Can't help but notice that you suddenly went from "Stealership" to "Dealership"
As far as a fee do you get paid for what you do for a living? Almost all Dealership technicians get paid on Flat Rate which means unless their doing a job that pays something their not making any money.

I'm not in your area but I would recomend taking it to someone that Knows how to Properly Diagnose your issue even if you have to pay a "FEE" You'll save in the long run. Or you could just throw an alt on it and hope that fixes it if it dosent you could then throw a PCM at it and hope for the best But would'nt it Suck after you spent all that money to find out that all along it was just a minor wiring issue?
See what I mean about saving money by getting it properly diagnosed?

I have a buddy at a chevy dealership that has diagnosed it through all the testing and he thought it was my alternator going out. So according to a mechanic it was the alternator. I changed it and still get the code and check gauges. I am praying to god its not my pcm and hopefully a bad wire somewhere. I just don't know which one I should be looking at.
