A stored code P0622 means that the powertrain control module (PCM) has detected a malfunction with the generator field coil control circuit. The F simply reiterates the field coil control circuit is at fault. The field coil is probably most recognizable from its windings which are visible through the vent holes on most alternators.

2022年7月15日 · Repair Information for P0622 Chevrolet code. Learn what Generator F-Terminal Circuit means, location and how to repair?

2017年6月23日 · OBD II fault code P0622 is a generic code that is defined as “Alternator, field control -circuit malfunction”, and is set when the PCM (Powertrain Control Module) detects an abnormal, or the absence of the PWM (Pulse Width Modulated) signal that turns the field winding in the generator on and off.

2022年7月15日 · What does the P0622 code mean on a Chevrolet? The P0622 code indicates a malfunction in the generator (alternator) F-terminal circuit, which can affect charging system performance.

The fault code P0622 can be caused by the following: low battery charge, a faulty generator, an open or shorted generator harness, poor electrical connection in the generator circuit, or a faulty Engine Control Module (ECM). Fixing Code P0622: Simple Steps To Resolve The Issue!

2024年12月19日 · The P0622 code stands for “Generator Field/F Terminal Circuit.” It’s triggered when the PCM detects a continuity or voltage issue in the generator field control circuit. Possible causes for this trouble code to be set include a faulty alternator, malfunctioning batter, faulty PCM, and wiring problems.

2022年7月15日 · When the engine is running, the duty cycle should be between 5 - 99%. The Diagnostic Trouble Code (DTC) will be set if the ignition is ON, and the engine OFF (Prior to Ignition ON, the ignition must have been OFF for at least 5 s), the ECM detects a PWM signal that is greater than 65% for 5 s. Check the 'Possible Causes' listed above.

What Does P0622 Code Mean? OBD-II Code P0622 is defined as a Generator Field/F Terminal Circuit. The Alternator recharges the Battery when the engine is running. The Alternator is controlled by the engine control module (PCM). If the PCM detects an incorrect signal from the Alternator, the PCM will set code P0622. Ask our experts about P0622.

What Is the P0622 Code? Can I Still Drive? The P0622 OBD-II diagnostic error code indicates an error in the generator field/F terminal circuit that is responsible for charging the car’s...

2023年11月24日 · P0622 means there’s a problem with how your car’s computer (the PCM) controls the alternator, the part that charges the battery. If the alternator isn’t managed properly, your car might not charge the battery correctly, which can lead to issues like the battery running out of power or other electrical problems.
