By Ezra Lane If you're facing the P0762 error code in your Nissan, it means your Shift Solenoid B is stuck in the "on" position. This issue can hinder smooth gear transitions, cause the transmission to remain in a single gear, or result in slipping; it often leads to a noticeable decline in fuel efficiency. The common causes include electrical faults, blocked transmission filter, or low transmission fluid. Diagnosing this requires an OBD-II scanner, multimeter, and sometimes a transmission fluid pressure gauge. Addressing it quickly is crucial, as delays can compound the damage. Exploring this topic further will unveil more crucial insights and potential solutions.
P0762 Nissan Code Meaning
The P0762 code in a Nissan indicates Shift Solenoid Valve C is stuck "on," affecting gear shifting.
Causes include faulty wiring, low transmission fluid, or internal damage.
Resolution involves inspecting the solenoid, connections, and fluid, with repair costs typically between $250 and $600.
Error Code P0762 Symptoms
If you notice a P0762 error in your Nissan, you might experience some noticeable driving issues. Your car may not handle or perform as expected.
Here are some things you might experience:
- Rough or Slow Shifting: Your car might've trouble changing gears smoothly. You could feel it hesitate or jerk when shifting.
- Transmission Slipping: It might seem like the car isn't speeding up as it should when you push the gas pedal, leading to a drop in power.
- Stuck in Gear: In serious cases, the car mightn't change gears at all, keeping you in one gear.
- Poor Fuel Economy: The engine works harder when the transmission isn't efficient, causing more wear and increasing fuel usage.
Watch for these signs, as they point to a problem needing attention.
Causes of Nissan P0762 Fault Code
To fix the P0762 error code in your Nissan, it's important to know why it happens. This code means Shift Solenoid Valve C is stuck in the 'on' position, which can cause problems with your car's transmission.
Here are some common reasons:
- Electrical Problems: If the solenoid or its wiring is faulty, it might stay 'on' when it shouldn't.
- Clogged Transmission Filter: A dirty filter can block fluid flow, causing low lubrication and pressure, which may make the solenoid stick.
- Low Transmission Fluid: Not enough fluid can reduce the pressure needed for the solenoid to work right.
- Transmission Issues: Mechanical problems inside the transmission or with the solenoid can cause it to get stuck.
Fixing these issues might involve replacing parts or adding more transmission fluid.
Tools Needed to Diagnose
To diagnose the P0762 code in a Nissan, you'll need some specific tools to check and fix the shift solenoid issue. Here's what you should gather:
- OBD-II Scanner: Use this to read the error code and see what's wrong with the transmission.
- Multimeter: This helps check if the wiring and connectors are working properly and if there's a good electrical connection to the solenoid.
- Transmission Fluid Pressure Gauge: This checks the transmission fluid pressure, which is needed for the transmission to work correctly.
- Basic Toolset: Includes wrenches and screwdrivers for reaching and replacing the solenoid or related parts.
Also, have a transmission fluid dipstick and a funnel ready. These are used to check and refill the transmission fluid, keeping the system running smoothly.
With these tools, you can deal with the P0762 error code effectively.
How to Fix P0762 Nissan Error Code – Step by Step
Step 1:
Begin with a comprehensive diagnostic scan to confirm the presence of the P0762 Nissan error code and check for any additional related issues. This ensures you're addressing the correct problem without overlooking other potential faults.
Step 2:
Examine the electrical connections and wiring linked to Shift Solenoid Valve C. Look for signs of damage or corrosion that could hinder operation.
Corroded or damaged connections can lead to malfunctions in solenoid performance, triggering the P0762 error code.
Step 3:
Inspect the transmission fluid filter. A clogged filter restricts fluid flow, which is crucial for the transmission's proper function.
If you find any blockage, replace the filter to restore proper fluid dynamics within the system.
Step 4:
Verify the level and quality of the transmission fluid. Low or poor-quality fluid can cause inadequate lubrication and cooling.
Refill or replace the fluid according to the manufacturer's specifications to ensure optimal performance and prevent future issues.
Step 5:
If these steps don't clear the error, consider replacing Shift Solenoid Valve C.
Ensure all connections are secure when installing the new solenoid to avoid any future errors related to poor installation.
Common Diagnosis Mistakes
Mechanics often focus just on the shift solenoid when looking into the P0762 Nissan code. You might do this too and miss other issues causing the problem.
- Check Wires and Connections: Look at the wires and connections around the shift solenoid. Bad connections can act like a stuck solenoid.
- Look at Fluid Levels: Make sure the transmission fluid isn't low. Low fluid can seem like a solenoid problem. Always check this first.
- Check the Fluid Filter: See if the transmission fluid filter is clogged. A blocked filter can stop fluid flow and cause solenoid trouble. Don't swap the solenoid before checking the filter.
- Think About Internal Damage: Damage inside the transmission can keep causing issues, even if you change the solenoid. Check the whole transmission for any damage.
P0762 Nissan Repair Cost
Fixing the P0762 error code on a Nissan usually costs between $250 and $600. The price depends on your car's make and year. This cost includes both parts and labor.
You'll likely spend $100 to $300 on parts, mainly to replace the Shift Solenoid Valve C. Labor can range from $150 to $300. Prices can vary based on where you live due to different labor rates.
Some cars make it easy to reach the solenoid, which can cut down on labor time and cost. But if your car needs parts taken apart to get to the solenoid, costs could be higher.
To get a good deal, call a few local repair shops. They can give you a specific estimate based on your car's condition and where you live. This way, you can find a fair price and reliable service.
Picking the right mechanic matters, as poor handling of solenoid issues might cause bigger transmission problems later.
Related Error Codes on Nissan

What Is the Warranty Coverage for Solenoid Repairs on a Nissan?
If your Nissan is still under the basic 3-year/36,000-mile warranty or has an extended powertrain warranty, solenoid repairs might be covered. Check your warranty details to be sure. It's best to use authorized Nissan dealerships for any repairs to make sure they are covered.
How Does Weather Affect Solenoid Functionality?
Weather can affect how a solenoid works. If it's too hot or too cold, the fluid inside can get too thick or too thin. Also, wet weather can cause electrical problems. These issues might make your car shift gears differently or not work right.
Are There Aftermarket Solenoids That Meet Nissan Specifications?
Yes, you can buy solenoids for your Nissan from other brands. Make sure they fit your car model and read reviews. These solenoids often have warranties, so they're a good choice if you want to save money and keep your car running well.
Can Solenoid Issues Affect Nissan's Fuel Efficiency?
Yes, if your Nissan has solenoid problems, it can use more fuel. This happens because the car doesn't shift gears smoothly, making the engine work harder. Fixing the solenoid can help the car run better and save gas.
How Often Should Solenoids Be Inspected in Nissans?
Check the solenoids in your Nissan every 30,000 to 60,000 miles. If your car has transmission problems or warning lights, look at them sooner. Regular checks help keep your car running smoothly and catch any problems early.
