P0795 - OBD Trouble Code

<<See All OBD Codes

The PCM relies on the hydraulic pump pressure for shifting, it also relies on factors such as speed of the vehicle, speed of the engine, engine load, and throttle position. The PCM will set P0795 code if the pump pressure is not in congruence with the what the PCM requests. The check engine light will be illuminated. Mostly vehicles will have the check engine light illuminated when the error is set, however some may require multiple failure cycles before the light can come on.

When the fault with the electronic pressure control solenoid, or the solenoid circuit is present the OBD P0795 code will be set by the Powertrain Control Module (PCM). The hydraulic pressure used to actuate shifting is regulated by the electronic pressure control solenoids. They also help in proper functioning of the torque converter.

What causes this problem with the Pressure Control Solenoid C Malfunction?

• A poor electronic pressure control solenoid
• Failed transmission
• Blockages in the fluid passages of the transmission
• A failure of the PCM
• Dirty and contaminated transmission fluid/ low level of fluid

If you are facing OBD error code P0795, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

Here’s a list of few common symptoms you may come across:

• Inability to shift
• Failure of the torque converter
• Transmission is set to limp mode by the PCM
• Poor fuel economy
• Harsh shifting
• Slipping of the transmission
• Transmission overheating

It is very important to fix the fault code P0795. So here are some ways with which you can correct this issue:

• Replacement of all damaged or faulty wiring, connectors, or components
• Repairing any leaks in the transmission
• Replacing the hydraulic pump if it is bad
• Replacing any faulty electronic pressure control solenoids
• Replacing the PCM if it is bad
• Rebuilding the transmission if contaminants like debris is detected in the transmission pan. Install a new torque converter when rebuilding the transmission

However, if you face any issue then we have stocked a wide range of best priced Electronic Pressure Control Solenoid, Transmission, Transmission Fluid, Power Control Module and more to help you out in fixing your car.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• Pull out the dipstick of the transmission and investigate the fluid. it should be clean, if it smells burnt or looks strange, then look for debris in the transmission pan. Debris present are an indicator of a bigger problem, with the transmission and may require to be rebuilt.
• The next inspection you have to run is of the wiring, connectors and components, for any damage.
• Now hook the scanner to the vehicles diagnostic and download all the codes and freeze frame the data and then clear all the codes and take your vehicle of test drive.
• Make sure the transmission is filled to a good level and fix any leaks.
• Start your vehicle and wait for reaching normal operating temperature. Now you can test the system, and see if the code returns.
• If the code is restored, it’s time to hook up the manual pressure pump to the transmission and use the hydraulic pressure diagram, and you can successfully test the pressure levels of the hydraulic pump. Now compare the findings with those of the manufacturers and see if they’re correct.
• After replacing the faulty hydraulic pump, if the code is still faulty, and if after clearing the codes the code still returns, you will have to make use of the DVOM or digital volt/ohm meter and test the reference voltage as well as the ground signal of the electronic pressure control solenoid.
• If either one of them is open then you will have to check the continuity and resistance of all circuits that are related. All related modules will have to be disconnected in order to avoid any damage.
• If all else isn’t resolving the problem, you will have to test the PCM for any faults. However, PCM failure is rather rare, so be careful about diagnosing it.
• Now clear all the trouble codes and test the system and see if the code still returns.

Common Mistakes When Diagnosing the P0795 Code

• Wrongly replacing the high-pressure pump
• Overlooking malfunction of the wire
• Overlooking issues with electronic pressure control solenoid
