P0964 - OBD Trouble Code

<<See All OBD Codes

The trouble code P0964 can be explicated as Pressure Control Solenoid "B" Control Circuit/Open. If the transmission control module would observe some issues with one of the valves, including a voltage signal stating that the B control circuit is remaining open, or not receiving the reference voltage needed to operate, then the P0964 error code would be stored in.

The brighter you are, the more you have to learn! That’s why we are here to provide you more knowledge about the P0964 trouble code. It is a generic powertrain code which is associated to the transmission. It includes the defects in the pressure as well as some faults in the sensor. If the engine control module would receive a signal that the pressure control solenoid for the B control circuit is open, then the P0964 trouble code would start appearing.

What causes this problem with the Pressure Control Solenoid "B" Control Circuit/Open?

• Some problems related to eroded connector
• Malfunctioning PCM
• The wiring might not be functioning properly
• The transmission fluid might be adulterated
• Minimal transmission filter
• Quirks in the transmission pump
• Transmission valve body might be flawed
• There can be distorted pressure control solenoid
• The hydraulic passages might be closed

3. Engine Control Module - Are you facing some faults in your Engine Control Module? Don’t worry and get them replaced or else P0964 code can turn up.
4. Body Control Module Component - Common cause behind this P0964 error code can be some fault in Body Control Module Component. So it will be a good decision to replace them now.
5. Auto Transmission Control Module - Body Control Module Component is perfectly fine but still but having that trouble code P0964 flashing? In such a situation your Auto Transmission Control Module might be faulty. Why don’t you think of getting that replaced?
6. Electronic Control Unit - The P0964 code can also arise due to some issues in Electronic Control Unit. So it is advised to replace them as soon as possible.
7. Automatic Transmission Filter - P0964 code does not really end up spoiling your Electronic Control Unit, but it might also accompany few Automatic Transmission Filter issues. We have best Automatic Transmission Filter with us.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0964 here:

Common Symptoms:

• Possible misfire like symptoms
• Elevation in the overall fuel consumption
• A lot of warmth in the transmission
• Transmission may move firmly
• Appearance of the service engine soon light
• Transmission slink when it is moving
• Transmission is set into limp mode by the powertrain control module

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P0964:

• Make sure to mend the faulty pressure control solenoid
• The malfunctioning transmission valve body should be repaired or replaced as per the need
• It is essential to restore the flawed wiring
• Repair or replace the quirky powertrain control module
• Rehabilitate the defaults in the transmission pump
• The connectors should be cleaned properly
• Recondition the non-functioning fluid and filter

If you want to easily diagnose this trouble code, then you must follow the steps which are mentioned here as below:

The first step in the troubleshooting process for any malfunction is to investigate the technical service bulletins for the particular automobile by year, model and power plant. There can be some situations where it would save a lot of your precious time in the long run by pointing you in the correct way. After that the next step is to perform a thorough visual inspection to check the associated wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots. Then check the connectors and connections for security, corrosion and damaged pins. This process must include all wiring connectors and connections to the battery, alternator, PCM, and the voltage regulator. Some charging system configurations may be more complex including relays, fuse-able links and fuses in some circumstances. The visual inspection should also include the condition of the serpentine belt and the belt tensioner. The belt should be tight with a sight amount of flexibility and the tensioner must move freely and apply the appropriate amount of pressure on the serpentine belt. Based on the vehicle and the charging system configuration a defective or damaged voltage regulator will require an alternator replacement in most circumstances. The advanced steps would become very automobile specific and would need an equipment which is acceptable to perform correctly. These procedures would need a digital multimeter and the particular technical references for the vehicle. A charging system diagnostic device would be the perfect tool which can be used in this situation. The need of voltage would keep on changing as it all depends upon the particular year as well as model of your automobile. The voltage of the battery should be appropriately 12 volts and the alternator output must be higher to compensate for electrical draws and charge the battery as well. The lack of voltage indicates a faulty alternator, voltage regulator or a wiring issue. If the alternator voltage output is in the appropriate range, this is an indication that the battery requires replacement or a wiring issue exists. If there is absence of a power source or ground, continuity testing may be required to check the integrity of the wiring, alternator, voltage regulator and other components. Continuity tests should always be performed with the power removed from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance unless otherwise specified by the technical data. Resistance or no continuity is an indication of quirky wiring that is open or shorted and it should be restored as per the need.

Common Mistakes When Diagnosing The P0964 Code

• Non performance of the engine
• Failure in the transmission pump
• Internal transmission might start failing
• Non observance of the driveline
