How to correct problem code p0622 - PT Cruiser Chrysler Cars & Trucks

P0430 means the Cat has been damaged.
P0622 means the alternator is not charging properly. Etc etc.
Probably the general cause is a broken wire.

do not guess, or go broke fast or throw parts blind
ask why , ask how to do tests.
i will read your service manual to you and not shove out lies about ford and chevy to you, ever. as most do on the web.
the correct answer are this Chrysler car.
here it is the real words from maker
P0622-Generator Field Control Circuit the word Generator is really Alternator, my 1960 bug had a real DC generator then, and is not now. in this car
the field coil is really the bobin coil after ring brushes.
so the wire fell off the Alt REAR
OR THE BRUSHES DIED AFTER SPINNING 17 LONG LONG YEARS. I BET THIS IS IT.
A BAD ALT.
BUT I DO BRUSHES MY SELF. (OLD SKOOLWAYS)

P0622 has to do with the alternator field coil. If possible, have your alternator inspected/tested. Check circuit for wiring issues- broken/exposed wires, etc.

There is no such code for a 2005 Ford Freestyle. P0641 does not exist in the code chart. It goes from P0622 to P0645. Are you sure you wrote it down correctly?
