By Ezra Lane When your Nissan registers a P0770 code, it indicates a shift solenoid E malfunction, which disrupts your car's gear shifting abilities. This issue usually stems from a faulty solenoid, low transmission fluid, or electrical problems. Diagnosing this involves checking fluid levels and using a multimeter to measure the solenoid's resistance. Repair costs typically range between $250 and $600, depending on the severity of the malfunction. Symptoms such as harsh shifting, erratic gear changes, and an illuminated check engine light will persist until the faulty components are replaced and the system is thoroughly tested to ensure the problem is effectively resolved. By further exploring these steps, you'll gain a deeper insight into the necessary resolutions.
P0770 Nissan Code Meaning
The P0770 code in a Nissan indicates a problem with Shift Solenoid Valve E, affecting gear shifts.
Causes include a faulty solenoid, low transmission fluid, or electrical issues.
Diagnosis involves checking fluid levels and solenoid resistance.
Repair costs typically range from $250 to $600.
Error Code P0770 Symptoms
When your Nissan shows a P0770 code, it means there's a problem with the shift solenoid E in the transmission.
Here's what you might notice:
- Harsh or Delayed Shifting: Gears might shift harder or slower than normal. This can make driving uncomfortable and hint at transmission issues.
- Inability to Shift Gears: Sometimes, the transmission may not shift at all. This could result in losing power and possibly getting stuck.
- Erratic Shifting Behavior: You may experience unexpected gear changes or slipping. This behavior can be surprising and affect vehicle control.
- Check Engine Light On: The dashboard light will likely turn on. This signals that the car's system has detected a transmission issue needing attention.
These symptoms suggest problems with the transmission that can affect how well your Nissan drives.
Noticing these signs helps in keeping your vehicle running smoothly.
Causes of Nissan P0770 Fault Code
When your Nissan shows a P0770 code, it usually means there's a problem with Shift Solenoid Valve E. This valve helps control the flow of transmission fluid, which is needed for changing gears.
Here are some common reasons for this code:
- Bad Shift Solenoid Valve E: The valve mightn't work right. This affects how the transmission fluid moves, which can make gear shifting hard.
- Low Transmission Fluid: If there isn't enough fluid, the system can't work smoothly. This can cause problems with the solenoid and other parts.
- Blocked Fluid Filter: A dirty filter can block fluid flow. This makes it hard for the solenoid to do its job and might cause the P0770 code.
- Wiring Problems: If wires are damaged or connectors are rusty, the solenoid mightn't get the signals it needs, leading to the code.
Fixing these problems can help keep your car's transmission working well.
Tools Needed to Diagnose
To diagnose the P0770 code on your Nissan, you'll need some basic tools. Having these ready will make the process smoother and help you avoid changing parts unnecessarily.
Here's what you should gather:
- OBD-II Scanner: Use this to read and clear error codes from your car's computer. It will show if the problem comes back after fixing it.
- Multimeter: This checks if the Shift Solenoid Valve E is working right by measuring electrical resistance. Make sure it matches the manufacturer's guidelines.
- Basic Hand Tools: Have a set of sockets and wrenches handy. You might need them to reach and change the shift solenoid if it's not working.
- Transmission Fluid Gauge: This checks fluid levels and pressure. Look for low fluid or a blocked filter that might be causing problems with the solenoid.
Also, keep a repair manual specific to your vehicle. It gives the details you need for the right steps and specs during the repair.
How to Fix P0770 Nissan Error Code – Step by Step
Step 1:
Begin by checking the transmission fluid level in your Nissan. If the fluid is low, either top it off or replace it entirely, as inadequate fluid levels can trigger the P0770 error code.
Step 2:
Proceed to inspect the wiring and connectors associated with Shift Solenoid Valve E. Look for any signs of damage or corrosion that could be affecting its operation.
Step 3:
Utilize a multimeter to measure the resistance of Shift Solenoid Valve E. If the resistance is outside the manufacturer's specified range, it indicates a problem, and you'll need to replace the solenoid.
Step 4:
After completing the necessary repairs or replacements, use an OBD-II scanner to clear the Diagnostic Trouble Code (DTC) from your vehicle's computer.
Step 5:
Reassess the vehicle to ensure that the changes have resolved the issue and that the P0770 code doesn't reappear.
Common Diagnosis Mistakes
When dealing with the P0770 error code in a Nissan, several common mistakes can occur during diagnosis. It's important to avoid these errors to prevent unnecessary repairs.
- Check Transmission Fluid First: Always verify the fluid level before suspecting the shift solenoid. Low fluid can mimic solenoid problems and trigger the P0770 code.
- Inspect Wiring and Connectors: Look for damage or corrosion in the wiring. These issues can disrupt solenoid function and lead to a wrong diagnosis.
- Test the Solenoid: Use a multimeter to check Shift Solenoid Valve E. This helps determine if the solenoid is the issue or if the problem lies elsewhere.
- Examine the Fluid Filter: A blocked filter can limit fluid flow, resembling solenoid failure. Check this part before concluding your diagnosis.
After repairs, clear the diagnostic trouble code (DTC) and take the car for a test drive to ensure the transmission works properly under regular driving conditions.
P0770 Nissan Repair Cost
When dealing with the P0770 code on your Nissan, repairing it could cost between $250 and $600. This includes both parts and labor.
Let's break it down:
- Parts Cost: The main part to replace is the Shift Solenoid Valve E. This can cost anywhere from $100 to $300. The price depends on whether you choose aftermarket parts or OEM parts. OEM parts are usually more expensive.
- Labor Cost: Expect to pay another $150 to $300 for labor. This cost varies based on the service provider and the complexity of the job for your car model. Labor rates also differ by location.
- Extra Costs: Be ready for possible extra expenses. If the mechanic finds low transmission fluid or a clogged filter, these will need fixing too. This ensures your transmission works well after the repair.

Related Error Codes on Nissan
When your Nissan's transmission seems off, error codes can help figure out what's wrong. If you see code P0770, it means there might be a problem with shift solenoid E. Sometimes, this code appears with others like P0750, P0755, and P0760, which suggest different solenoid issues. These codes often show up together if there's a wider issue affecting solenoids.
Other codes to watch for include P0740 and P0745, which might point to problems with the torque converter or pressure control solenoid. Code P0845 can indicate trouble with the transmission fluid pressure sensor, affecting how the transmission works. Seeing these codes together can help you identify broader issues with the transmission.
Here's a quick guide to these codes:
| Code | Description | Impact |
|---|---|---|
| P0750 | Shift Solenoid A Problem | Related to solenoid, like P0770 |
| P0745 | Pressure Control Solenoid Problem | Can affect transmission pressure |
| P0845 | Transmission Fluid Pressure Sensor | Affects how the transmission works |
Looking at these codes together can help solve transmission issues more effectively.
