Error Code P0965: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0965 can be explicated as Pressure Control Solenoid "B" Control Circuit Range/Performance. There can be a lot of situations where the automatic transmissions will include at least three pressure control solenoids which are known as solenoid A, B and C. The transmissions which are new would have more gears as well as more solenoids. There are a lot of error codes which are related to the "B" solenoid control circuit and some of the most common include P0964, P0965, P0966 and P0967. If the powertrain control module would detect an issue with the transmission pressure control solenoid "B" control circuit, then it would give rise to the P0965 trouble code. The particular code which is triggered depends upon the specific fault which the PCM has detected.

Do you want to gain some more knowledge about the P0965 trouble code? If there is an appearance of the P0965 trouble code, then it would mean that the engine control module has discovered the levels of voltage to be outside the specifications set by the manufacturer. This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

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

• Confined transmission filter
• Defaults in the transmission pump
• There can be polluted transmission fluid
• There can be defective transmission valve body
• Obstructed hydraulic passages
• Faulty pressure control solenoid
• The connector might be burned
• Powertrain control module might be flawed
• Some issues related to the wiring

It is vital 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 P0965 here:

Common Symptoms:

• Check engine light might come into signal
• Excessive heat in the transmission
• Transmission may move firmly
• Growth in the fuel consumption
• Transmission glide when shifting
• Some misfire like symptoms
• The PCM may put the transmission into limp mode

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• The malfunctioning wiring should be repaired or replaced as per the need
• You must flush transmission to clean passages
• Make sure to mend the faulty connectors
• It is essential to change the fluid and filter
• Carefully adjust the faults in the pressure control solenoid
• The engine control module should be restored to working order
• Recondition the non-functioning transmission valve body
• Adjust the flawed transmission pump

Here are some steps which you should follow in order to diagnose this fault code:

• If you want to diagnose the P0965 fault code, then you must research 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 flawed wiring that might be opened or shorted. It is very important to repair it properly.

Common Mistakes When Diagnosing The P0965 Code

• Some issues related to the engine misfire
• Flaws in the transmission pump
• Malfunctioning internal transmission
• Driveline related problems
