P0658 Low voltage level in the drive power circuit “A”

P0658 – OBD-II Trouble Code Technical Description

Error P0658 indicates that the voltage in the drive power supply circuit “A” is too low (compared to the value specified in the manufacturer’s specifications).

What does the fault code mean P0658?

Trouble code P0658 indicates that actuator "A" supply circuit voltage is too low. This means that the powertrain control module (PCM) or other auxiliary control modules in the vehicle have detected that the power circuit voltage for a specific part of the vehicle system is below the manufacturer's specified level.

Possible reasons

Trouble code P0658 can be caused by various reasons:

• Problems with wiring and connections: Poor connections, corrosion, or breaks in the wiring between the PCM and the “A” drive may cause this code to appear.
• Drive “A” malfunction: Problems with the “A” drive itself, such as a faulty motor or other components, can cause trouble code P0658.
• Problems with the PCM or other control modules: Faults in the PCM or other vehicle control modules can cause P0658 if they do not provide enough voltage to the power supply.
• Power problems: Unstable or insufficient power supply to the vehicle may cause low voltage in the power supply circuit of drive “A”.
• Malfunctions of other components: Other components that affect the "A" drive power circuit, such as relays, fuses, or additional sensors, can also cause P0658.
• Grounding problems: Insufficient grounding can result in low power supply voltage, which can cause P0658.

It is important to conduct thorough diagnostics to determine the exact cause of the P0658 code and make appropriate repairs.

What are the symptoms of a fault code? P0658?

Symptoms of DTC P0658 may vary depending on the specific cause and context, but some typical symptoms include:

• Check Engine Light: The appearance of the Check Engine light on your car's dashboard is one of the most obvious signs of a problem.
• Loss of power: Low voltage in the “A” drive power supply circuit may result in loss of engine power or rough operation of the engine.
• Unstable engine operation: The motor may shake or rattle due to unstable power supply.
• Gear shifting problems: On vehicles with automatic transmission or related systems, problems with the A-drive power supply circuit may result in shifting problems.
• Unstable operation of electronic systems: There may be problems with the operation of other electronic systems in the vehicle, such as the engine management system, ABS system or fuel management system.
• Unusual sounds or vibrations: When the voltage on the A-drive circuit is low, unusual noises or vibrations may occur in the area around this assembly or in other parts of the vehicle.

These are just a few of the possible symptoms that may be associated with the P0658 trouble code. It is important to note that when such symptoms appear, it is recommended to diagnose the system to determine the cause and eliminate the problem.

How to diagnose a fault code P0658?

The following procedure is recommended to diagnose DTC P0658:

1. Using the Diagnostic Scanner: Connect the diagnostic scanner to the OBD-II port and read the error codes. Make sure the P0658 code is present and make a note of any other error codes that may accompany it.
2. Checking wiring and connections: Inspect the wiring and connections associated with the “A” actuator and the PCM for breaks, corrosion, or poor connections. Check the integrity of the wires and make sure that all connections are secure.
3. Measuring voltage: Using a multimeter, measure the voltage in the power supply circuit of drive “A”. Make sure the voltage meets the manufacturer's specifications.
4. Checking drive “A”: Carry out a thorough check of drive “A” for correct installation and possible malfunctions. If necessary, check the condition of the motor and other drive components.
5. Checking the PCM and other control modules: Diagnose the PCM and other vehicle control modules for errors and problems related to signal processing from the “A” drive.
6. Checking the power supply: Check the stability and quality of the vehicle's power supply, including the condition of the battery, alternator and grounding system.
7. Checking other components: Check other components that affect the power supply circuit of drive “A”, such as relays, fuses or additional sensors.
8. Use of specialized equipment: In some cases, it may be necessary to use specialized equipment for more detailed diagnostics and data analysis.

After diagnosing and identifying the cause, it is recommended to carry out the necessary repairs or replace components.

Diagnostic errors

When diagnosing DTC P0658, the following errors may occur:

• Insufficient checking of wiring and connections: Incorrect diagnosis may occur if the wiring and connections associated with the “A” drive and the PCM have not been thoroughly inspected. Breaks, corrosion or poor contacts can cause low voltage in the power circuit.
• Incorrect interpretation of multimeter readings: Malfunctions in the power circuit may be caused by changes in voltage. However, incorrectly reading or interpreting the multimeter readings can lead to an incorrect diagnosis.
• Neglect of other possible causes: Trouble code P0658 can be caused not only by problems with the A-drive power circuit, but also by other factors, such as malfunctions of the PCM, other control modules, or the vehicle's power supply. Failure to check these components may result in a misdiagnosis.
• Inexperience or lack of training: Diagnostics of electrical systems requires certain skills and knowledge. Inexperience or lack of training can lead to misdiagnosis and further problems.
• Using inappropriate equipmentNote: Specialized equipment may be required to accurately diagnose the problem. Using unsuitable or incompatible equipment may cause erroneous results.
• The need for re-checking: After performing repairs or replacing components, you should recheck the system and clear the error code to ensure that the problem has indeed been corrected.

It is important to be aware of these possible errors when diagnosing the P0658 trouble code and to carry out the diagnostic process carefully and consistently to achieve an accurate result. If you are unsure of your diagnostic skills, it is recommended that you contact a qualified auto mechanic or auto repair shop.

How serious is the fault code? P0658?

Trouble code P0658, which indicates that drive A is too low, can be a serious problem that requires careful attention and resolution. A few reasons why this error code may be important:

• Power Loss and Performance Deterioration: Low voltage in the “A” drive power supply circuit may cause loss of engine power and poor performance. This may affect the overall performance and safety of the vehicle.
• Unstable engine operation: Unstable power supply may cause the engine to run unevenly, which may result in shaking, rattling or other unusual symptoms.
• Risk of damage to other components: Low voltage may adversely affect the performance of other electronic components of the vehicle, such as the engine management system, ABS and other safety systems. This may lead to additional malfunctions and damage.
• Potential hazard: If the problem remains unresolved, it may pose a potential risk to driving safety, since incorrect operation of the engine or other vehicle systems can lead to an accident on the road.

Overall, the P0658 trouble code requires serious attention and diagnosis to identify and correct the cause of the problem. It is necessary to take measures to solve this problem as soon as possible in order to prevent possible negative consequences for the car and the safety of its owner.

What repair will help eliminate the code? P0658?

The repair to resolve the P0658 code will depend on the specific cause of this error. Several possible activities:
