"Delete Error Code Permanently, Disable DTC Error Code Function for P2757 in the ECU"

In extreme cases, we even have the option to permanently remove the specific DTC P2757 and disable the function of the specific error code in the ECU. All other fault code functions will then continue to work to protect the engine. This is different from clearing an error code with a diagnostic device. We have the option to permanently remove the function of the specific error code, so that it never comes back. Also emergency running that occurs on the specific error code can be solved in most cases.

Of course we prefer to first try to solve the cause of the error code, but sometimes the only solution is to permanently disable the DTC function of P2757.

If an issue would be detected in the torque converter clutch pressure control solenoid circuit by the automobile’s onboard powertrain control module, then the P2757 fault code would start appearing.

What causes this problem with the Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance/Stuck Off?

• There can be distorted torque converter clutch pressure control solenoid
• Torque converter clutch pressure control solenoid harness is open or small
• Torque converter clutch pressure control solenoid circuit might have inadequate electrical connection

Replace/Repair These Parts To Fix OBD Code P2757

1. Transmission Control Module - The TCM monitors the functioning of the transmission system and will store this OBD code if the fluid pump does not function properly. Contrary, the TCM can also be faulty and might need reprogramming and replacement. Thus, replace it now!
2. Electronic Control Unit - ECU monitors the temperature differences in the boost converter with the help of the temperature sensors to prevent the converter from overheating and malfunctioning. Thus, replace faulty ECU immediately.
3. Intake Valve - Intake valve is a valve in the cylinder head of an internal-combustion engine that opens at the proper moment in the cycle to allow the fuel-air mixture to be drawn into the cylinder. Thus, replace it now!
4. Engine Control Module - ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
5. Powertrain Control Module - Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
6. Diagnostic Tool - In order to be that DIY guy, you need few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come in handy to do so, so why not have a look?

Easy Diagnosis Of Engine Error OBD Code P2757

Do you wish to diagnose P2757 error code easily? Here are some steps which you should follow in order to diagnose this fault code:

You will need a scanner and a digital volt/ohmmeter to diagnose this error code successfully. Generally every vehicle with an automatic transmission produced since the mid-eighties is equipped with some type of computer controlled automatic transmission system. A sophisticated computerized control system is utilized by the OBD-II equipped vehicles that calculates a number of engine drivability inputs with vehicle speed inputs, engine/turbine speed inputs, and transmission output speed inputs to determine the desired gear ratio necessary to achieve maximum fuel efficiency, to optimize engine performance, and provide the greatest engine and transmission longevity. The input data is calculated by the powertrain control module and initiates upshifting and downshifting by using strategically designed shift solenoids to actuate fluid transfer between the hydraulic circuits of each set of corresponding gears. If there are a lot of stored shift solenoid codes then it would indicate that a transmission component slipping or delayed engagement condition has occurred. The automatic transmission uses a high pressure pump to circulate fluid through the transmission hydraulic circuits in the transmission housing and valve body. Now if the transmission pressure is not sufficient enough to actuate gear changes, this type of code might exist. Insufficient fluid pressure is most often caused due to less or grubby transmission fluid condition. You must begin the transmission diagnosis with an inspection of the transmission fluid dipstick. Just make sure that the fluid level should be within manufacturer’s specified recommendations and that the fluid is in nice condition. Fluid that smells burned or unusual in any way should be considered inappropriate. If the fluid is burned, then it would indicate that the transmission has been operated during a low fluid level condition and may have experienced catastrophic internal mechanical failure. If the fluid smells or appears burned, then the transmission pan should be removed and inspect for the presence of clutch material and other debris. If such contaminants are present in the transmission pan, a total rebuild, fluid flush and replacement, and a new torque converter would be needed before the transmission will function correctly. If no debris is found in the transmission pan, then you should check all internal wiring and connectors. Search for shorted or burned wiring and replace circuitry and connectors as required. Most applications will require replacement of the full internal transmission harness if discrepancies are noted. If the system wiring, connectors, and components appear to be in normal working order, connect the scanner to the diagnostic connector and record all stored trouble codes and freeze frame data. The intermittent conditions can be diagnosed easily with the help of this information that may have contributed to this code being stored. Now once the codes have been cleared, operate the vehicle to see if the code returns. If the code fails to immediately return, then there is a situation of intermittent condition. Intermittent conditions can prove to be challenging to diagnose and in extreme cases may have to be allowed to worsen before a correct diagnosis can be made. Now if the transmission fluid is in decent shape, but the overall level of the fluid is less, then you should add enough fluid to locate a leak and repair it. Fill the transmission with fluid, allow the vehicle to reach normal operating temperature, and test drive it to see if the transmission operates normally and to determine whether the code will return. If the transmission operates normally and the code doesn’t return, then it was likely caused by transmission slippage due to a low fluid level/pressure condition. If the code is returning back again and the transmission slips or suffers from delayed engagement, check pump pressure using a manual pressure gauge. Obtain a hydraulic pressure diagram pertaining to the vehicle and thread the end of the gauge into the appropriate opening on the transmission housing to record pump pressure. Your findings should be compared with manufacturer’s specifications and make repairs as per the requirements. Typical causes of low pump pressure include clogged hydraulic passages, a defective pump, faulty shift solenoids, or a faulty electronic pressure regulator. There would be a need of transmission removal in the pump replacement and partial disassembly. If the code immediately returns, and the transmission seems to operate normally, then inspect for reference voltage and ground signals at the affected shift solenoid. If either the reference voltage or ground circuits are open, then a digital volt/ohmmeter should be used to check for continuity as well as resistance in all circuits. Repair or replace system circuits/connectors as required and retest the system to ensure that repairs were successful. Using the manufacturer’s wiring diagram for the affected shift solenoid, test all related circuits and the solenoid itself for resistance and continuity and compare your findings with manufacturer’s specifications. Repair or replace system circuitry, connectors, and/or components that fail to coincide with manufacturer’s specs. Always retest the system to ensure a successful repair. If all system circuits are intact connect the scanner to the diagnostic connector and attempt to manually activate the shift solenoid/s. If the shift solenoid functions properly and all circuits coincide with manufacturer’s specifications, suspect a defective PCM. Just keep in mind that PCM failure is rare and it will require reprogramming during replacement. If the shift solenoid fails to activate manually, replace the solenoid (or solenoid pack) and retest the transmission control system.
