P2856 OBD Error Code: Problem & Solutions

 <<See All OBD Codes

The trouble code P2856 can be defined as Clutch "B" Pressure Charge Performance. The signals which come from the switches and sensors control the clutch pressure control solenoid. The clutch pressure is adjusted to be suitable to the engine load state and vehicle driving state. Then it would become possible to finely control the clutch hydraulic pressure with high precision and there would be the attainment of the smoother shift change characteristic

It is always good to learn more! That is the reason why we are here to help you out in gaining more knowledge about the P2856 error code. The transmission should detach when it is coming to an end. Now if the transmission would fail to disengage correctly, then the P2856 trouble code would start flashing up.

What causes this problem with the Clutch "B" Pressure Charge Performance?

• Some flaws in the high clutch & reverse brake solenoid valve
• Defective control valve assembly

1. Automatic Transmission Module - Sometimes the transmission module is unable to communicate or correctly anticipate the speed of the vehicle and thus creates difficulty in gear shift leading to sluggish acceleration, throttle response and stalling. Thus, can also hamper a lot of components physically and thus must be checked and replaced, if required.
2. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
3. Transmission Fluid Pump - Faulty transmission fluid pump can cause harsh shifts and audible transmission noise. This leads to decreased performance and chances of increased physical damage to the transmission components. Thus, replace it immediately.
4. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
5. Transmission Fluid Pump Harness - Damaged transmission fluid pump harness can cause problematic transmission performance and can lead to transmission slipping, rough shifts, fuel leakages and delayed engagements. Buy new harness now!
6. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
7. Diagnostic Tools - It is always advisable to use the correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in an efficient manner. Buy new quality diagnostic tools from us today!

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

• As an initial step the mechanic will carefully inspect the vehicle with the help of a scanner.
• After this, the technician will connect a scanner to the diagnostic code so that he can recover all the codes and freeze frame data.
• Note down this information as it can clearly help for further diagnosis.
• After careful inspection, he will reset the code and test drive your vehicle to check for reappearance of the codes.
• He will know that an intermittent condition persists, if the code does not return instantly.
• But if the error code returns quickly, the vehicle is test driven, and then he has to inspect the transmission fluid.
• If any of the clutch "B" pressure is damaged, the mechanic will replace them quickly.
• Most often, whenever the mechanic carries out any repair work, he will reset the code and test drive your car, to check if the codes return immediately. This can preferably help the mechanic to know what caused this error code in the vehicle.

Common Mistakes When Diagnosing The P2856 Code

• Malfunctioning internal transmission
• Wiring related issues
• Diminishing transmission fluid level
