P0622 on Chrysler
Generator Field "F" Terminal Control Circuit
P0622 on Chrysler vehicles indicates generator field "f" terminal control circuit. Au7o has documented this code across 1 Chrysler model — most commonly on 300. A fault in the generator field 'F' terminal control circuit that the PCM uses to control alternator field excitation and regulate output. The circuit is open, shorted, or not responding as commanded.
Common Causes of P0622
- •Faulty alternator/voltage regulator
- •Open or short in the 'F' terminal circuit
- •Corroded/damaged wiring or connectors
- •Poor ground
- •Internal PCM driver fault
