P0776 OBD Error Code: Problem & Solutions

<<See All OBD Codes

What causes the pressure control solenoid to get stuck? What are its symptoms and causes? This is a general type of error code which means that the level of fluid which is needed for the vehicle does not coincide with the actual amount that was used. Also, you will notice that in few vehicles, the check engine light will not be triggered despite several fail cycles.

The automatic transmission in the vehicle is controlled by the powertrain train control module through changing degrees of hydraulic pressure, providing the converter and the shift control solenoid. The pressure of the system is controlled by at least one electronic pressure control solenoid, which is supervised and managed by the PCM.

Every system depends on calculation although it slightly varies for different makes and models, depending on the load and speed of the engine, throttle position and the speed of the vehicle so as to measure the right degree of pump pressure that is needed for proper operation. If the amount of the transmission fluid does not match with the original amount, then the P0776 error code will be stored and the check engine light will be lit. Also, in some vehicles the light will not be lit despite several failures.

What causes this problem with the Pressure Control Solenoid B Performance or Stuck Off?

• Improper working of the electronic pressure control solenoid.
• Mechanical errors or failures in the internal transmission pump.
• The fluid passage of the internal transmission has hydraulic blocks.
• The transmission fluid is less or dirty.
• PCM is defective.

1. Pressure Control Solenoid - If there are any blocks in the pressure control solenoid or if it is broken / damaged, then the P0776 error code will be stored in your vehicle. Replace them at the right time to avoid the appearance of this error code.
2. Powertrain Control Module - In most vehicles, a faulty or a broken power control module is the main reason for the appearance of this error code. Replace or fix the component as soon as possible.
3. Connectors - Visually inspect the terminals of the connectors for damages or if they are broken, If you find them damaged, get them replaced with the right replacement part from Parts Avatar.
4. Automatic Transmission Filter - You have to inspect this element for any blockages. If there are blocks, clear them off the filter and re-fix them.
5. Body Control Module Component - In order to avoid the P0776 error code getting stored, the defective body control module must be replaced.
6. Auto Transmission Valve Body - Are there any damages? Looking to replace this defective part? Grab them from Parts Avatar at affordable price. 

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 P0776 here:

Common Symptoms

This error code could result in a wide range of symptoms. In certain situations, the mechanic may not notice anything wrong with your vehicle. At other cases, the shift function of your vehicle will be permanently disabled. You may notice that the torque converter clutch of your vehicle fails to lock or unlock. As a very rare case, when the P0776 error code is stored, the PCM will respond by pushing the vehicle into limp-in mode.

Other common symptoms include:

• Slipping of the transmission.
• Shift may be rude.
• Efficiency of the fuel is reduced.
• Transmission keeps heating. 

Want to correct the Trouble Code P0776? Read these points mentioned below:

• The defective electrical component needs repair or replacement.
• The transmission fluid must be filled or changed.
• If your clutch is broken due to low transmission fluid, then it must be changed.
• As a very rare case, you must replace the PCM.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0776 code to be stored:

• Basically, the technician will use a scanner tool in order to find out which error codes are stored in the powertrain control module of your vehicle. Then he will proceed with the diagnosis process to check the correct level and the quality of the transmission fluid. Even at times, the technician will check the transmission pan. Finally, he will visually inspect the wires, connectors, PCM as well as other components.

Common Mistakes When Diagnosing the P0776 Code

Most of the times, the mechanic will lay his eye on the high-pressure pump of your vehicle and he may even try to replace or change them, though the actual problem may lie with wiring malfunctions or even the electronic pressure control solenoid.
