The camshaft and crankshaft are vital components that play a vital role in operating the engine efficiently. The Engine Control Module (ECM) of your car continuously observes the performance of these parts. Learn the P0014 code meaning, causes, symptoms, and prevention.
When something goes wrong with the camshaft timing or the variable camshaft timing system, the ECM triggers the P0014 trouble code.
This diagnostic trouble code can stem due to various causes, potentially leading to significant engine damage if neglected. Therefore, instant diagnosis is important to prevent such consequences. This guide explains the P0014 code causes and how to fix it.
Code P0014 Definition
The P0014 code stands for “Exhaust Camshaft Timing – Over-Advanced Bank 1.”
What does the P0014 Code Mean?
The P0014 code signifies that the engine control module (ECM) of your car has identified a discrepancy wherein the Bank 1 exhaust camshaft’s timing is more advanced than instructed by the ECM. This excessive advancement issue can take place during either the advancing or retarding phases of the camshaft timing.
The P0014 engine code is relevant exclusively to vehicles equipped with a Variable Valve Timing (VVT) system.
VVT system has the responsibility to improve fuel economy and engine efficiency, enabling the engine to generate increased rpms and power. This is achieved by precisely regulating the ignition of the air-fuel mixture through the manipulation of exhaust and intake valve opening and closing.
Causes of P0014 Code
Optimal engine performance depends on the accurate synchronization between the crankshaft and the camshaft. To achieve this, your engine relies on the readings coming from the camshaft position sensor and crankshaft position sensor.
Various factors can trigger the P0014 code. Some issues, like dirty engine oil or inadequate oil levels, can be addressed personally. In contrast, more intricate causes involve faulty parts within the VVT system itself.
The following are the most common causes of P0014 trouble code:
- Dirty or aged engine oil
- Poor oil pressure
- Insufficient oil levels
- A malfunctioning camshaft position sensor
- An issue with the exhaust camshaft position solenoid actuator
- A bad VVT solenoid
- Damaged wiring connected to the exhaust camshaft solenoid actuator
- Clogs oil lines connected to the VVT solenoid
- Incorrect camshaft timing
- Faulty crankshaft position sensor
- Clogged oil filter
- An issue with the Engine Control Module (ECM)
P0014 Trouble Code Symptoms
- Abnormal engine noises, such as rattling or knocking
- Illuminated check engine light
- Hard to start the engine
- Rough idle
- Poor engine performance
- Engine vibration or shaking
- Reduced fuel efficiency
- Rough acceleration
- Failed emissions tests

How to diagnose the P0014 Code?
When the vehicle triggers the P0014 code, it is not recommended to drive for a long distance. When your car shows this code, you should fix it promptly. To fix the P0014 code, you must have all the necessary tools. Follow the below given basic steps to diagnose engine code P0014:
- Begin by linking an OBD-II scan tool to identify potential trouble codes associated with the P0014 issue. If any codes linked to the crankshaft or camshaft position sensors emerge, prioritize their diagnosis as they could potentially resolve the P0014 error.
- Check the oil level and condition by using a dipstick. If oil levels are low, refill the oil reservoir and conduct a road test to validate the resolution. If your oil is dirty, opt for an oil replacement.
- Ensure the proper inspection of the crankshaft position sensor to check its proper functionality.
- Check the oil flow and oil pressure within the oil system.
- Check the camshaft to ensure its performance and alignment with the crankshaft positions sensor.
- Perform a visual inspection of the connectors, wires, and other related parts connected to the timing components, VVT solenoids, and camshaft position sensor for signs of corrosion, wear, or damage.
- Visually inspect the timing belt for damage.
- Check the performance of the VVT solenoid.
- Inspect the oil filter for damage.
- Conduct a compression test to check the overall health of your engine.
Common P0014 Diagnosis Mistakes
- Considering timing components are faulty
- Not checking the oil level and oil condition
- Not following manufacturer instructions
- Concentrating solely on the camshaft position sensor and overlooking the Variable Valve Timing (VVT) or Variable Camshaft Timing (VCT) system
- Not addressing other related codes and solely focusing on the P0014 code
- Not inspecting the Variable Valve Timing (VVT) or Variable Camshaft Timing (VCT) system
What repairs can fix the P0014 Code?
If your vehicle triggers the P0014 code, you need to repair or replace one or more of the following parts:
- Clearing the codes and performing a test drive
- Adding more if it is insufficient
- Replacing the bad exhaust camshaft position solenoid actuator
- Flushing the dirty engine oil and refilling the oil reservoir
- Replacing the timing belt if needed
- Cleaning or replacing the VVT solenoid
- Replacing the bad crankshaft position sensor
- Changing the faulty camshaft timing control valve solenoid
- Change the faulty camshaft sensor
- Repairing the damaged wires
How serious is the P0014 Code?
The P0014 code is a serious trouble code. It indicates an issue with the camshaft timing. The correct camshaft timing is very important to operate the engine efficiently.
Therefore, upon detecting the P0014 engine code, it is recommended to stop the vehicle and fix the issue. Neglecting a timely resolution could lead to potential piston-to-valve contact, ultimately incurring higher expenses.
Driving with this code for a long time may also lead to the complete failure of your engine.
How to Prevent P0014 Trouble Code
- Maintain proper oil levels
- Always use good quality oil recommended by your vehicle’s manufacturer
- Address the illuminated check engine light promptly
- Follow recommended service routines
- Exercise smooth and gradual acceleration and deceleration
- Monitor your car performance constantly
How Much Does It Cost To Repair P0014 Code?
You need to repair or replace one or more of the below-given parts to fix the trouble code P0014:
|Oil filter replacement||$40 to $80|
|Oil control valve replacement||$140 to $480|
|Oil pump replacement||$180 to $1,600|
|Timing belt replacement||$900 to $5000|
|Intake valve timing solenoid replacement||$280 to $580|
Can I drive with the P0014 code?
The fault code P0014 is considered serious. Driving your vehicle with this code present without conducting a comprehensive diagnosis is strongly discouraged. Ignoring a potential camshaft timing problem could lead to catastrophic engine failure, potentially resulting in costly engine replacement.
Can low oil cause the P0014 code?
Yes, low engine oil is one of the major causes of the P0014 code. Inadequate oil results in diminished oil pressure, which can adversely affect the camshaft solenoid and tensioner. These components are often regulated by oil pressure, and reduced pressure can affect the camshaft timing, ultimately leading to the emergence of the P0014 code.
How can I fix the P0014 code?
To address the P0014 code, a systematic approach is essential. Start by identifying any associated trouble codes. Should you encounter codes linked to the VCT or VVT control valve, a thorough assessment of this valve becomes essential. You also need to check the oil level and its condition. Additionally, scrutinize the camshaft timing to ensure there are no timing irregularities.
How much does it cost to replace the camshaft sensor?
In the event of a faulty camshaft sensor, replacing it is usually an economical endeavor. The sensor itself typically ranges from $40 to $220, with the replacement process often taking around 25 minutes. Consequently, the complete cost of replacing a camshaft sensor generally falls between $70 and $320 for most vehicles. It’s worth noting that costs might be higher for certain cars.
Can a bad spark plug cause P0014?
It’s important to note that the P0014 code pertains to problems with camshaft timing or the corresponding readings. Conversely, spark plugs have limited relevance to this issue. Thus, it’s highly unlikely for a malfunctioning spark plug to trigger the P0014 trouble code.
What are the symptoms of P0014 Toyota?
The P0014 Toyota refers to the issue related to camshaft timing. An issue with the camshaft timing may induce rough operation, potentially leading to challenges like challenging starts, engine stalling, poor fuel efficiency, and poor idling. While these symptoms are indicative, it’s essential to recognize that they might have multiple origins beyond timing-related issues.
