By Ezra Lane When your Nissan displays the P0014 code, it indicates that the exhaust camshaft timing on Bank 1 is excessively advanced. You might notice symptoms such as reduced power during acceleration, erratic idling, increased stalling, diminished fuel efficiency, and unusual engine noises. Typically, the causes include a malfunctioning Variable Valve Timing (VVT) solenoid, the presence of engine oil sludge, blocked hydraulic ports in camshaft sprockets, incorrect engine oil viscosity, or faulty camshaft or crankshaft position sensors. Addressing this issue promptly is crucial to avoid severe engine damage. If needed, start with checking and replacing the engine oil and VVT solenoids, and from there, investigating electrical connections and sensor functionality can reveal deeper insights.
P0014 Nissan Code Meaning
A P0014 code in a Nissan indicates advanced exhaust camshaft timing on Bank 1.
Possible causes include a faulty VVT solenoid, engine oil sludge, or wiring issues.
Addressing this promptly is crucial to prevent further engine damage or reduced vehicle efficiency.
Error Code P0014 Symptoms
If you see a P0014 code in your Nissan, it means there's an issue with the timing of your car's exhaust camshaft.
Here's what you might notice:
- Lack of Power: Your car may not accelerate as quickly or feel as responsive.
- Shaky Idling: The car might shake or vibrate more when it's just sitting there.
- Frequent Stalling: It could stall more often, especially when you're slowing down or stopping.
- Worse Gas Mileage: You could be filling up the tank more often because it's using more fuel.
- Odd Engine Noises: Listen for strange noises, especially when you're braking, as these might mean something's wrong with the timing.
These problems can mess with your driving and might lead to more engine troubles if not fixed soon.
Causes of Nissan P0014 Fault Code
The P0014 fault code in a Nissan can pop up for a few reasons, mainly related to the exhaust valve timing system.
Here's what might be causing it:
- Bad Exhaust Valve Timing Control Solenoid: This part helps manage the timing of exhaust valves. If it's not working right, it might cause the P0014 code.
- Engine Oil Sludge or Gunk: Sludge or gunk in the engine can block the system that controls valve timing, leading to the fault code.
- Blocked Hydraulic Ports: These ports in the camshaft sprocket need to be clear to adjust valve timing properly. If they're blocked, it may cause problems.
- Wrong Engine Oil Viscosity or Low Oil: Using oil that's too thick or too thin, or not having enough oil, can mess with the valve timing system, causing this code to appear.
- Faulty Camshaft or Crankshaft Sensors: These sensors send timing signals. If they're not working, they can trigger the P0014 code.
Checking these areas can help solve the problem.
Tools Needed to Diagnose
To fix the Nissan P0014 error code, you'll need some tools to help you figure out what's wrong and make any needed repairs.
Having the right tools makes it easier to find the cause of the problem related to timing and valve control.
Here's a list of tools you might need:
- OBD-II Scanner: Used to read the P0014 code and other codes.
- Multimeter: Checks the electrical connections and voltage of the variable valve timing solenoids and wires.
- Engine Oil Pressure Gauge: Measures oil pressure, which is important for checking if low pressure is an issue.
- Mechanic's Stethoscope: Lets you hear any strange sounds from the camshaft or timing parts.
- Basic Hand Tools: Needed for taking apart and replacing parts like the VVT solenoids, and for general maintenance like oil changes.
Each tool has its own role in helping you find and fix the P0014 error.
How to Fix P0014 Nissan Error Code – Step by Step
Step 1:
Check the engine oil level and quality. Low or dirty oil can hinder the Exhaust Valve Timing Control system. Change the oil if necessary, using the manufacturer-recommended viscosity for optimal performance.
Step 2:
Inspect the Variable Valve Timing (VVT) solenoids. Test them to ensure they're operating correctly. If you find any defects, replace the faulty solenoids to restore proper function.
Step 3:
Examine the wiring and connectors associated with the EVTC system. Look for signs of damage, corrosion, or poor connections that could impair electrical flow.
Repair or replace any compromised components to maintain system integrity.
Step 4:
If the problem persists, consider checking the camshaft and crankshaft position sensors. These sensors can affect timing control if they malfunction, requiring more technical expertise to diagnose and replace if necessary.
Step 5:
If the above steps don't resolve the issue, seek professional help. Advanced diagnostics might require examining timing components, which could involve more complex mechanical work.
Addressing these steps methodically will help you fix the P0014 error code effectively.
Common Diagnosis Mistakes
When dealing with the P0014 error code on your Nissan, be aware of common mistakes that can lead to incorrect diagnoses:
- Check Engine Oil: Always look at the oil level and condition. Bad oil can mess with the VVT system.
- Test Solenoids First: Before swapping out VVT solenoids, make sure they're actually broken. Testing them can save you money.
- Look at Wiring: See if the wires and connectors are damaged or corroded. These issues can seem like solenoid problems.
- Consider Other Causes: Don't rush to blame the timing chain or belt. Think about oil sludge or clogged hydraulic ports too.
- Update ECM Software: Keep the ECM software current. Old software might give wrong error codes.
P0014 Nissan Repair Cost
Fixing a P0014 code in your Nissan can cost between $200 and $500. This depends on the problem and where you live. Simple fixes like an oil change or cleaning a sensor will be cheaper. Bigger jobs, like replacing a broken variable valve timing solenoid, will cost more.
Where you live affects the cost. Mechanics charge by the hour, usually between $75 and $150. This means the same repair can cost different amounts at different shops.
Parts are another cost to consider. Good solenoids and sensors help your car's camshaft timing work well. Buying quality parts can prevent frequent repairs later.
Routine maintenance can help avoid these issues. Regular oil changes and system checks can catch problems early.
Stick to your Nissan's maintenance schedule to keep repair costs down.
Related Error Codes on Nissan
When you see the P0014 error code on your Nissan, it might be useful to look for other codes that could show more problems with the Variable Valve Timing (VVT) system. If P0014 pops up, other codes might also appear, hinting at related issues. Checking these codes helps figure out if the problem is just one part or more widespread.
Here's a quick list of related codes and what they mean:
| Code | What It Means | Effect on VVT System |
|---|---|---|
| P0011 | Timing is too advanced on Bank 1 | Timing might be too far ahead |
| P0013 | Exhaust valve control issue | Solenoid might not be working well |
| P0340 | Problem with camshaft sensor | Timing affected by sensor errors |
There are other related codes like P0024 and P0345. P0024 shows similar timing issues but on another side of the engine, which might mean a large timing problem. P0345 could point to more sensor problems needing attention.

People Also Ask
What Is the Role of the Exhaust Camshaft in an Engine?
The exhaust camshaft in a car's engine helps control when the exhaust valves open to let out gases after burning fuel. This helps the engine run better, use less fuel, and reduce pollution. It can change timing based on how fast you're going and how hard the engine is working.
How Does Over-Advanced Camshaft Timing Affect Fuel Efficiency?
When the camshaft timing is too advanced, it messes up the engine's timing for mixing air and fuel. This makes the engine use more gas because it can't work well. So, the car may end up drinking more fuel than usual.
Can P0014 Code Affect the Nissan's Emissions?
Yes, the P0014 code can make your Nissan's emissions go up. It happens because the exhaust valve timing isn't right, which makes the engine burn fuel poorly. This leads to more bad stuff like NOx and hydrocarbons coming out of your car.
Are There Aftermarket Parts Recommended for Fixing P0014?
Yes, you can use aftermarket parts to fix the P0014 issue. Brands like Aisin and Duralast offer good VVT solenoids. These parts meet the standards of original parts. Before buying, read reviews and make sure they have good warranties.
Does Altitude Impact the P0014 Error Occurrence?
Yes, being at a high place like a mountain can make the P0014 error happen more. The air is thinner up high, which can make problems with your car's exhaust valve timing worse. This might cause the error code to show up.
