Message: [QUOTE="Wildman, post: 1265571, member: 18533"] The DTC P0620 when the GENCOM circuit or A sense circuit are open or shorted to ground. This DTC can also set when the GENCOM circuit is shorted to voltage. I would begin by inspecting the generator connector (3 pin) C102A. This connector often gets fatigued from heat and vibration, leading to charging system issues and DTCs. If the connector is worn or damaged, you can purchase a replacement connector pigtail at your local dealer and solder it in. If you don't find any issues with the connector, inspect the circuits between the generator and PCM and between the battery and generator for any damage, chafing, or improper routing. If no harness damage is found, the suspect root cause is a faulty generator that is internally shorting the command signal sent from the PCM, causing the DTC to set. [/QUOTE]
