I have researched these codes, you must have some kind of issue with the alternator, did you test it with a load bank that pulls max amps from system? I suspect either the connectors to the alternator are loose or the alternator has a bad diode in the rectifier bridge circuit, have it tested again, kragen does it for free as well as others.

SOURCE: need to know what p0622 and p2503 diagnostic codes

Sounds more like an alternator problem. Check output voltage of alternator, code P2503 indicates low voltage. Check/clean all connections at battery and alternator, as well as check all fuses/relays under hood in fuse relay box, just in case fuse blown as well. If all checks out good, you may need a new alternator.

Our 4x4 Dodge ram 1500 is running rough after we replaced a busted radiator. It gave out code p304 and p2503. My husband took off all the coils and battery connections and cleaned them and dried them.


P0304 Code Cylinder 4 Misfire
The p2503 code is - charging system low output. If the engine ran ok before the radiator blew, then components and wire are probably still wet or moist. Especially with cylinder #4 , take off spark plug wire from spark and from coil and dry out the inside of the boots. Also, try blowing the alternator dry with a hair drier.

2001 Dodge Intrepid- What does P0622= Generator F-term. Field F control, and P0403= EGR flow circuit malfuntion mean? Thank you


If you've replaced those parts according to the codes, you need to have the codes cleared from the computer, otherwise the car will think you still have the bad parts on, and stay in what they call Limp Mode! Sometimes you can take it to an Autozone, and they can clear it for you! Otherwise you need to have a shop clear those computer codes for you!

I have a 2005 dodge grand caravan. The battery light came on so I had the battery checked and it checked out ok. The alternator is relatively new (8 months). It has now develope a miss in the engine. We...


The code P2503 is Charging system voltage is low

Take a Muti meter and check the voltage output of the alternator Put the red lead on the red wire of the alternator and the black lead on the negative side of the battery and then start the engine. The voltage should read between 13.9 - 14.2 volts if it does not then you have a bad alternator or voltage regulator. Either way you have to replace the alternator because the voltage regulator is built in to the alternator.It does not matter if it is only 8 months old some times you can get bad parts. Hope fully you kept the receipt for the alternator because being only 8 months old it would be covered under a parts warraty which is usually at least 1 year on alternators.If you had a garage replace it then take it back to them they should replace it under warranty and it should not cost you a dime for labour either since they installed the first one. If you can't check the output voltage yourself take it to Autozone or Partsource they usually do this test on alternators for free.
