As your car owner, you’re always looking to be more aware of what’s going on under the hood. But even if you’re mechanically inclined, some check engine light warnings can be disconcerting. The P0014 code It’s one of those codes.
The P0014 code refers to a problem with the bank 1 exhaust camshaft. When this code is activated, the engine control module, ECM, says that the camshaft is too advanced.
VVT System Operation
VVT systems They are among the most common methods of controlling variable valve timing in an engine. They work by using oil pressure to change the position of a valve sprocket, which in turn changes the position of the exhaust camshaft.
The system changes valve timing on the fly, improving performance and fuel economy.
The P0014 code often means there is a problem with the engine timing. This code appears when the camshaft position (CMP) sensor does not detect the correct timing for the engine.
The engine control unit (ECU) is responsible for monitoring and controlling all engine functions. When there is a problem with engine timing, the ECU usually gives the code P0014.
What Does Code P0014 Mean?
OBD-2 code P0014 means that the bank 1 exhaust camshaft has advanced beyond the ECM instructions. Advance occurs when the ECM tells the camshaft to retard or advance.
The P0014 code is activated when variable valve timing sets the camshaft position too far from the normal location indicated by the ECM.
In most cases, this code is caused by a timing chain problem, where the chain has become too stretched and can no longer keep the camshaft in sync with the crankshaft.
This can lead to a number of problems, including poor performance, engine knocking, and even engine failure.
The exhaust camshaft is driven by the timing belt, which must be synchronized with the crankshaft for the engine to run properly.
If there is a problem with the exhaust camshaft or its timing, the engine will run poorly and may even damage the valves. So if you see the P0014 code, it’s time to take your car to a mechanic to have it checked.

What Are the Symptoms of Code P0014?
The P0014 code It is often an indication of a more serious problem with the engine and should not be ignored. If you experience any of the following symptoms, take your car to a mechanic as soon as possible.
1. Difficulty starting
One of the most common symptoms of an error code P0014 It is the difficulty in starting the engine. It’s because the cylinders may not be firing properly, making it difficult for the engine to turn over.
2. Increased fuel consumption
As a result of the misfiring cylinders, the car will not run as efficiently as before. It means you will probably see an increase in fuel consumption.
3. Noise and vibration
The engine will also produce more noise and vibrations than usual. You may notice this most when the engine is cold and idling.
4. Other symptoms
A P0014 code is activated when a sensor informs the ECM that there is a problem with the camshaft. These are the other symptoms:
- The check engine light will come on.
- The engine could have rough idling problems.
- The engine could stop for no apparent reason.
- Emissions test failure.
- Detonations in the engine.
What Are The Causes Of Code P0014?
The P0014 code It has several possible causes. Causes include problems with the exhaust camshaft, oil viscosity, and solenoid.
There are some potential causes of the P0014 code, which are mentioned below.
1. Poor oil quality
One of the most common causes of the P0014 code is poor quality or loss of oil pressure. If the oil is not up to par, it can cause the VVT system to fail.
Therefore, you need to make sure that you are using the correct oil for your car. Additionally, you must change it according to the manufacturer’s instructions.
2. VVT System Failure
If there is a problem with the VVT system, the P0014 code may appear. There could be a problem with the solenoid, oil pressure, or timing.
How to Diagnose Code P0014
Now that you know what the P0014 code is, let’s see how to diagnose and repair it.
- First, determine the appearance of the code using the OBD-2 scanner.
- Before performing any repairs, check the wiring and sensor connections near the bank 1 camshaft.
- The next step is to check the engine oil level. It should be the viscosity recommended by the manufacturer. Use the vehicle’s service manual to determine what the viscosity of the engine oil should be.
- Use OBD-2 scanner to check engine code. Check the freeze frame data to find exactly what triggered the code and when it was activated.
- Clear the code and start the car. Then, check the code again with the OBD-2 scanner.
- Use hand tools to disconnect the oil control valve from the exhaust camshaft. After disconnecting the OCV, observe the timing data. If the data changes, the valve works, so the problem is with a sensor or the ECM wiring.
- Using the vehicle’s service manual, the final step is to follow the precise tests for the code. If something is wrong, the car should be taken to a licensed mechanic for necessary repairs.
Here are the tools you need to diagnose the P0014 code correctly.
- Car service manual. It is a comprehensive resource containing information about the specific make and model of a vehicle. Additionally, this manual provides details on the location of particular components, how to troubleshoot, and how to properly maintain the car.
- Basic hand tools. Basic hand tools are essential for performing many car repairs. These typically include wrenches, screwdrivers, and pliers.
- Jumper Cables: In some cases, jumper cables may be necessary to bypass a fuse or start the car. Jumper cables are two metal cables that are connected with alligator clips.
- OBDII scan tool. An OBDII scan tool is a device that plugs into the car’s diagnostic port. You can use this tool to read and clear diagnostic codes and capture freeze frame data.
Perform a visual inspection
Perform a visual inspection It is an excellent way to diagnose the code P0014. By looking for common causes of this code, you can often fix the problem without taking the car in for repairs.
Check the wiring for damage to the wires that could cause a poor signal to the ECM. If you find a damaged cable, you must repair or replace it immediately.
You should also check the condition of the connectors. A failed or damaged connection may be the cause of this code. Make sure they are connected correctly and that there is no corrosion or damage.
The solenoid can also cause P0014. If it is damaged, corroded, or worn, you will not be able to control the valve properly. If the solenoid is damaged, you must replace it.
Check the condition of your engine oil
If you get a engine code P0014, it might be time to check your engine oil level. This code is usually caused by low oil levels, which can cause several problems with your car.
One of the main problems that occur when the oil level is low is that the engine will begin to misfire. It can cause all kinds of problems with your car, including poor fuel economy and performance.
In some cases, a misfire can even damage your engine.
If you have any of these problems, it is a good idea to check your engine oil level and make sure it is at the correct level. If not, you can add more oil to your car.
Additionally, the oil must be in good condition. A thick, sticky, dark oil without its properties can cause the code P0014.
