P0622 Chrysler - brand new battery and alternator passed test

Question

I have a 2002 Chrysler Concorde lx 2.7 engine. I recently got a battery light on my dash. I have replaced the battery and I have had the alternator checked and it passed all the tests. I made sure he ground and other connection were on surely and now the battery light has returned. I checked the code by doing the key test and I received p0622. I am frustrated because I cannot figure out what is going on with my care.

Answer 1

P0622 Generator field control circuit

The set condition for this code to occur is when the PCM tries to regulate the gerator field.What looks like a good connection may truly not be What may look like a good connection may not be so Here is a intake air temperature sensor where the connection on the back was making intermittent contact. Try wiggle the connection of the alternator (if the connection can be reached safely)if the light goes out you have a poor connection.
