What is code p0622

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.

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.

Generator field F control circuit malfunction

code p0622 refers to alternator ,field control-circuit malfunction causes--wiring ---alternator---battery---ECM. I would have the battery load tested first to check for loose for terminals and failing cells. Then check that the plug in the back of the alternator is tight

P0622 Generator Field "F" Control Circuit Malfunction

alternator my friend

Hi there:


DTC P0622 - Generator Field Control Circuit
This is a trouble code relates to the charging system and means that the Powertrain Control Module is trying to control the generator field with no result during monitoring.


This problem could be caused:
- open/shorted within the field control circuit between the PCM and the alternator ( a brown/gray wire ),
- generator ground circuit (brown/black wire),
- generator itself, or
- faulty PCM.




Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
