What is OBD-II Code P0795 – Pressure Control Solenoid C

OBD (On-Board Diagnostic) codes are codes transferred to a car’s OBD-II system when issues arise in any of the car’s systems. The system includes a wide range of sensors and other equipment responsible for ensuring the car operates at its optimal level. The P0795 code means that there is a problem with the pressure control solenoid C, specifically that the signal is low.

In this article, we will explore OBD-II code P0795 in detail. We will explain what the code means, and how to repair the issue associated with the code. We will also provide tips for car owners who may encounter this problem in the future. By the end of this article, you will have a better understanding of the OBD-II code P0795, its causes, and how to fix it.

What is OBD-II Code P0795 – Pressure Control Solenoid C

The pressure control solenoid is an essential component of your car’s transmission system. It is responsible for regulating the hydraulic pressure inside the transmission, which is used to shift gears. The P0795 code means that there is a problem with the pressure control solenoid C. The code is largely associated with automatic transmissions and may come up alongside other transmission control errors.

The code P0795 signifies that the engine control module (ECM) has registered that the pressure control solenoid C signal is low. The ECM does not only measure the amount of control pressure in the solenoid but also ensures the pressure meets the required level at every shift point. If the ECM detects that the pressure control solenoid C is not signaling correctly, the code P0795 is generated.

What Causes OBD-II Code P0795 – Pressure Control Solenoid C

Several factors may trigger the P0795 code, and they include:

1. Electrical problems: One of the main causes of the P0795 code is electrical issues. Damaged wiring or a short circuit increases resistance, leading to low pressure, and eventually triggering the P0795 code.

2. Failed pressure control solenoid C: Damage to the pressure control solenoid C due to wear and tear, contamination, or other factors may cause low pressure and trigger the P0795 code.

3. Low transmission fluid: Low transmission fluid levels may cause the transmission system to malfunction, leading to low pressure, triggering the P0795 code.

4. Malfunctioning ECM: A malfunctioning ECM may also cause the P0795 code. If the ECM fails to read the pressure control solenoid C signals accurately, it may assume there is low pressure and generate the P0795 code.

Symptoms of OBD-II Code P0795 – Pressure Control Solenoid C

Here are some of the most common symptoms that may indicate a problem with the pressure control solenoid C:

1. Transmission slips during a shift: Low pressure from the malfunctioning pressure control solenoid C may cause slipping during gearshifts, making the ride unpleasant and potentially dangerous.

2. Delayed engagement of gears: The delay in gear engagement signifies that your car’s transmission system is not operating optimally, and the issue may be associated with the P0795 code.

3. Hard shifts: Another common symptom of the P0795 code is hard shifts between gears, causing shock to the car’s occupants and causing wear and tear on the transmission system.

4. Illuminated check engine light: If the check engine light is on, you need to check the transmission system. An illuminated check engine light may be an indication of a problem with the pressure control solenoid C.

How to Repair OBD-II Code P0795 – Pressure Control Solenoid C

The solution to repairing the P0795 code largely depends on what is causing it. Here are some of the common ways to fix the P0795 code:

1. Repair wiring: If your car’s wiring has been compromised due to damage, it needs repairing or replacing. Ensure that the wires have the correct gauge and that they are correctly installed.

2. Replace the pressure control solenoid C: If the pressure control solenoid C is faulty, replace it as soon as possible. Ensure you get the right replacement part and have a transmission specialist fit it in your car.

3. Check and refill transmission fluid: Check your car’s transmission fluid levels and make sure they are at the right level. If it is too low, top it up to avoid any contamination issues that may exacerbate the low pressure problem causing the P0795 code.

4. Have a professional diagnose the problem: If you are not sure what’s causing the problem, have a trained mechanic look at the car. They will be able to diagnose the problem and recommend the best possible repair to solve the issue.

5. Reset the ECM: After repairs, reset the car’s ECM by disconnecting the battery terminals for about an hour or two. This ensures the car’s computer receives a power cycle and reboots, potentially eliminating the P0795 code.


Q. What is the cost of fixing the P0795 code?
A. The cost of repairing the P0795 code depends on several factors, including what caused the issue, the extent of the problem, and your car’s make and model. On average, the cost may range from $300 to $600.

Q. Can I still drive my car with the P0795 code?
A. Yes, it is still possible to drive the car with the P0795 code, although we strongly advise that you take your car for repair immediately. Continuing to use a car with the P0795 code may lead to a transmission failure, which is even more expensive to repair.

Q. How can I prevent the P0795 code from happening?
A. To prevent the P0795 code from happening, ensure you maintain your car’s transmission system correctly. Check the car’s transmission fluid regularly, change it as scheduled,and avoid driving in extreme conditions that may cause stress on the transmission system.

Q. What other issues can trigger transmission control errors besides the P0795 code?
A. Several other issues may trigger transmission control errors, including damaged sensors, damaged wires, or a malfunctioning transmission control module.

Q. Should I purchase an OBD-II scanner to diagnose the P0795 code?
A. Yes, you may purchase an OBD-II scanner to diagnose the P0795 code. An OBD-II scanner allows car owners to read the trouble codes generated by the car’s computer, providing a quick and accurate diagnosis.


The P0795 code can be a troubling issue for car owners, but it is not something that cannot be fixed. The above tips will help you diagnose and repair the P0795 code, whether it’s the wiring, pressure control solenoid C, ECM, or low transmission fluid causing the issue. When in doubt, seek professional help.

Remember, maintaining your car’s transmission system should be a priority. Regular transmission fluid changes and other maintenance will help to prevent issues like the P0795 code from happening in the first place.
