P0014 Technical Description
Camshaft Position ‘B’ – Timing Over-Advanced or System Performance (Bank 1)
If you’re seeing the P0014 trouble code, this guide will help you understand its meaning, symptoms, causes, and fixes. This code indicates an issue with your car’s exhaust camshaft timing.
I’ve seen this issue many times.
You’ll learn what the P0014 code means and how to fix it, so your car runs smoothly again. We’ll go through the technical details and common symptoms before diving into the causes and solutions.
Alright, let’s get started!
Key Takeaways
- P0014 indicates an issue with the exhaust camshaft timing on Bank 1.
- Symptoms include rough idling, poor acceleration, and the Check Engine Light.
- Common causes are a faulty VVT solenoid, low or dirty engine oil, and a worn timing chain.
- Fixes involve checking and replacing the engine oil, VVT solenoid, timing chain, and camshaft phaser.
- Diagnosing the issue requires inspecting various components and possibly using an OBD-II scanner.
- Consult a professional mechanic if the problem persists after initial repairs.

What Does P0014 Trouble Code Mean?
The P0014 trouble code means there’s an issue with the camshaft timing on your vehicle’s exhaust side, specifically for Bank 1.
Bank 1 refers to the side of the engine with cylinder 1. This code gets triggered when the Engine Control Module (ECM) detects that the camshaft timing is over-advanced beyond the normal operating range.
In simpler terms, your car’s computer thinks the exhaust camshaft is moving faster than it should. This can mess with the engine’s timing, which affects performance and efficiency.
The timing is controlled by the Variable Valve Timing (VVT) system, which adjusts the camshaft’s position to optimize performance and fuel economy.
When the VVT system isn’t working right, it can cause the camshaft to be out of sync.
Several things can cause this timing issue. It might be a problem with the VVT solenoid, which controls the oil flow to the VVT system.
If the solenoid gets stuck open or closed, it can mess with the timing. Other potential causes include low or dirty engine oil, a worn timing chain or belt, or issues with the camshaft phaser.
Ignoring this code can lead to bigger problems. Your engine might run rough, you might notice decreased fuel efficiency, or even damage to the engine over time.
It’s crucial to address this issue promptly to avoid more costly repairs down the road.
In short, the P0014 code means your exhaust camshaft timing is off. Identifying and fixing the root cause is key to keeping your engine running smoothly.
P0014 Trouble Code Symptoms
If your car has the P0014 trouble code, you might notice the following symptoms:

P0014 Trouble Code Causes
The P0014 trouble code can be triggered by several issues, including:
- Faulty VVT solenoid
- Low or dirty engine oil
- Worn timing chain or belt
- Defective camshaft phaser
- Problems with the oil control valve
- Issues with the ECM (Engine Control Module)
How To Fix A P0014 Trouble Code
Fixing a P0014 trouble code involves diagnosing the root cause and then addressing it. Here’s a step-by-step guide to help you through the process:
1. Check Engine Oil
Ensure the engine oil is at the correct level and in good condition. Low or dirty oil can affect the VVT system. If necessary, change the oil and filter.
2. Inspect the VVT Solenoid
Locate the VVT solenoid (usually near the camshaft). Check for any visible signs of damage or wear. You can also test the solenoid with a multimeter to ensure it’s functioning correctly. Replace it if it’s faulty.
3. Examine the Timing Chain/Belt
Inspect the timing chain or belt for wear or damage. A worn or stretched chain/belt can cause timing issues. If it’s not in good condition, it will need to be replaced.
4. Look at the Camshaft Phaser
The camshaft phaser adjusts the camshaft position. If it’s defective, it can cause timing to be off. Check for any signs of wear or malfunction and replace if needed.
5. Test the Oil Control Valve
The oil control valve regulates oil flow to the VVT system. Test its operation and ensure it’s not clogged or damaged. Clean or replace it as necessary.
6. Scan and Clear Codes
Use an OBD-II scanner to clear the P0014 code after making any repairs. Drive the car and see if the code returns. If it does, further diagnosis might be needed.
7. Consult a Professional
If you’re unable to pinpoint the issue or the problem persists, it may be time to consult a professional mechanic. They can perform more in-depth diagnostics and repairs.
By following these steps, you should be able to diagnose and fix the issue causing the P0014 trouble code, ensuring your car runs smoothly again.
