By Ezra Lane You've encountered the P0795 Nissan code, which highlights an issue with the Pressure Control Solenoid 'C' in your vehicle's transmission. This problem can significantly affect your car's gear shifting capabilities by causing erratic, harsh, or slow shifts, potentially resulting in a slipping transmission. To tackle this, you'll need to check the transmission fluid, inspect and test the solenoid connections, and ensure the wiring isn't damaged or corroded. Repair costs typically range from $300 to $600, where addressing it early can prevent costlier future damage. Addressing these issues promptly ensures improved safety and operational reliability of your vehicle, inviting further exploration into maintaining optimal transmission health.
P0795 Nissan Code Meaning
The P0795 Nissan code indicates an issue with the Pressure Control Solenoid Valve 'C' in the transmission.
Check transmission fluid levels and electrical connections.
If unresolved, further transmission inspection is needed to prevent additional problems and ensure proper gear shifting.
Error Code P0795 Symptoms
When the P0795 code pops up on your Nissan, it means there's an issue with the Pressure Control Solenoid Valve 'C' in the transmission.
This problem can lead to a few noticeable changes in how your car drives:
- Erratic Shifting: Your car might change gears unpredictably when you speed up or slow down. This can make driving feel unstable.
- Harsh or Slow Shifts: You may feel the car shifting gears too hard or taking too long to shift. This can disrupt the smoothness of your ride.
- Transmission Slipping: If it seems like your car is losing power, especially when you need it most, the transmission might be slipping. This means the power isn't getting to the wheels properly.
- Transmission Overheating: Watch for signs that the transmission is getting too hot. If it overheats, it can lead to more serious problems.
If your check engine light is on, consider these symptoms, as they might be linked to the P0795 code.
Causes of Nissan P0795 Fault Code
Several things can cause the P0795 error code in your Nissan, often relating to the transmission system. Knowing these can help pinpoint the issue and find the right solution.
- Bad Pressure Control Solenoid Valve 'C': This valve helps control pressure in your car's transmission. If it's not working right, your car mightn't shift gears smoothly.
- Problems with Wiring: If the wires connected to the solenoid are broken or have short circuits, the solenoid may not work properly.
- Low Transmission Fluid: If there isn't enough fluid, the solenoid might stop working. Low fluid means parts aren't getting enough lubrication or cooling, leading to wear and tear.
- Issues Inside the Transmission: Worn-out parts like gears or bearings can cause this error code. These problems affect how well the transmission works.
Tools Needed to Diagnose
If you want to figure out what's causing the Nissan P0795 error code, you'll need some tools to help you.
These tools will help you find the problem so you can fix it right.
Here's what you'll need:
- OBD-II Scanner: This gadget pulls error codes and shows data from your car's transmission. Make sure it can read codes specific to Nissan cars.
- Multimeter: Use this to check if the pressure control solenoid valve C is getting the right voltage. It also checks for broken wires or circuits that aren't connected.
- Pressure Gauge: This tool measures hydraulic pressure in the transmission. It helps you see if the solenoid is working as it should.
- Basic Hand Tools: Grab a set of wrenches and screwdrivers to reach and remove parts like the solenoid.
A Nissan service manual can also be handy.
It gives you clear steps and details so you know exactly what to do.
How to Fix P0795 Nissan Error Code – Step by Step
Step 1:
Conduct a diagnostic scan to confirm the presence of the P0795 error code and check for any additional issues. This step is crucial to ensure that you're addressing the correct problem.
Step 2:
Inspect the wiring harness and connections for the pressure control solenoid valve C. Look for any signs of damage, corrosion, or loose connections that could affect the solenoid's performance.
Step 3:
Use a multimeter to test the solenoid's functionality. Ensure it operates within the manufacturer's specified parameters. If it doesn't, you may need to replace the solenoid.
Step 4:
Check your transmission fluid levels. Low fluid can exacerbate issues with the solenoid and overall transmission performance. Top up with the appropriate type of fluid recommended by Nissan if necessary.
Step 5:
Clear the trouble codes from your vehicle's computer to reset the system.
Take your car for a test drive to ensure the P0795 code doesn't return and that your transmission's performance has genuinely improved. If the issue persists, further diagnostics may be needed to identify less obvious faults.
Common Diagnosis Mistakes
When dealing with the P0795 Nissan error code, pay attention to these common mistakes to avoid repeated issues:
- Check Fluid Levels: Make sure the transmission fluid isn't low. This simple check can prevent unnecessary complicated diagnostics.
- Inspect Wiring: Before replacing the solenoid, look at the wiring harness and connections for any damage or rust.
- Identify Real Causes: Don't just assume the solenoid is faulty. Look for other internal transmission problems that might be causing the issue.
- Scan for More Codes: Always check for other trouble codes. They can give important clues about the P0795 error.
Just clearing the error codes won't solve the problem. Fix the real issue to stop the P0795 error from coming back.
P0795 Nissan Repair Cost
If you need to fix the P0795 error on your Nissan, you might wonder about the cost. Usually, it can range from $300 to $600. The cost depends on what exactly needs fixing and how much labor costs in your area.
The key part you'll need to replace is the pressure control solenoid valve. This part can cost between $100 and $300. This price will affect the total repair cost.
Also, you'll need to pay for diagnostic scans to check the P0795 code, which can add another $100 to $150 to the cost.
If the problem involves low transmission fluid levels, you'll need to add the cost of replacing this fluid to your expenses. Keep this in mind when planning for repairs.
To get a clearer idea of the exact cost and any extra expenses, talk to a mechanic. They can give you advice based on their experience with similar problems and provide a more accurate estimate of what you might spend to fix the P0795 code on your Nissan.
