P0622 - OBD Trouble Code

<<See All OBD Codes

Want to know more in depth about the error code P0622? Let's get you started! This code reveals a defect that has been found in the generator field control circuit. The PCM or one of the other supporting control modules has detected this error. These control modules may consist of the alternative fuel control module, the body control module, the anti-lock brake control module, the instrument panel control module, the fuel injection control module, the turbo control module, the anti-theft module, the cruise control module, the traction control module, proximity alert module, and the climate control module.

The Powertrain control module (PCM) stores a P0622 trouble code, when it detects a problem with the generator field control circuit. To monitor the generator the PCM utilizes the generator turn-on signal circuit. When it is determined to take the control, it transmits a five-volt signal to the voltage regulator through the generator turn-on signal circuit.

This drives the voltage regulator to start regulating the generator field circuit. Once when the generator is enabled by the PCM, it is then independently regulated by the voltage regulator. Although, during this procedure, if an error is observed in the generator field circuit, this trouble code is stored.

Precisely, based on this problem, it could be recorded and reported by the body control module, the anti-lock brake control module, the alternative fuel control module, the anti-theft module, the turbo control module, the instrument panel control module, the climate control module, the cruise control module, the traction control module, the proximity alert module, and the fuel injection control module. The problem can be reported by the others too. The reason it becomes essential is because it could take several incidents before the check engine light is illuminated. It all relies on the module that outlines the issue to the PCM first.

What causes this problem with the Generator Field "F" Control Circuit Malfunction?

• A possible fault in the PCM
• A PCM programming error
• Generator field control circuit shorted or open
• Damaged or unsound alternator/generator

1. Powertrain Control Module - Facing the error code P0622? An unsound or damaged Powertrain control module can always be hazardous for the system also it is one of the prime causes behind the occurrence of the error code P0622.

If you are facing OBD error code P0622, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

The Symptoms contain a discharged battery, drivability issues, harsh shifting, low fuel economy, the engine may stop or run rough at idle, bad acceleration, a stored trouble code, and also a flashing service engine soon lamp. If this code is sets in, and a service engine soon lamp has not yet been lightened, the code may be shown as unresolved

• Complications with the engine drivability
• Engine halts when idling
• An inadvertent engine shut off
• Slow engine cranking
• Other various stored codes

After you know the symptoms of your vehicle?s problem, it becomes easy to detect it and get started with solving it. So, next on our list is few common steps to correct this issue with your vehicle?s.

• Restore or mend all the defective electrical components
• All the CAN?s pins should be disconnected and tested individually
• Change or repair the control module ground strap

Apart from the fuel injector, you might need to undergo few more replacements. You might need PCM, can scanner, alternator/generator, fuel rims, battery connectors, shift solenoid, body control module, fuel cleanser, transmission sensors, ECM modules, transmission control modules, pressure control solenoid and many other parts. Where to get them from? Well, if you want quality parts, then we can prove to be your dream destination.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0622 code to be stored:

• A certified mechanic should start the diagnosis by using an OBD-II scanner to inspect which codes have been stored by the PCM. Next, they should investigate and test the wirings and connectors before moving forward to do the same to the control modules.
• The Control Area Network (CAN) will most likely require to be examined as well, which could simply taking out every pin during the process. This would need the use of a diagnostic CAN scanner and memory-saving tool too.

Common Mistakes When Diagnosing the P0622 Code

Want to avoid a misdiagnose? Well, you need to avoid these mistakes in order to accurately fight back the error code P0622:

Many of the undiscovered problems could be playing a primal role in this code setting in again and again. So, in order to avoid this the mechanic must deal with one code at a time and fix them in this order by using the freeze frame feature of their OBD-II scanner.
