A vehicle’s variable valve timing (VVT) system improves engine performance and fuel efficiency. It regulates the opening and shutting of the exhaust and intake valves, in turn, controlling the fuel-air mix.
This control allows for more power, better fuel economy, or a balanced approach counting on the demand on the engine at any given time.
The P0014 OBD-II generic code is merely applicable to vehicles with variable valve timing and refers to a drag with camshaft timing, specifically the exhaust camshaft in bank 1, position “B.” This component is liable for controlling the valves which release engine carbon emissions.
What Does Code P0014 Mean?
OBD-II Trouble Code P0014 Description
“B” Camshaft Position – Timing Over-Advanced or System Performance (Bank 1)
First, the code is telling you where the error is. “Bank 1” is that the area of the engine containing the primary cylinder. Position “B” is an exhaust camshaft located either within the rear or right of the engine from the attitude of the driving force , counting on the make and model of the vehicle.
Next, the error code is stating that this camshaft is over-advancing, meaning it’s exceeding a threshold set by the ECM (engine control module) while advancing or retarding the camshaft timing.
Symptoms of Code P0014
Wondering the way to identify when the P0014 error code occurs? Spotting the matter early reduces the quantity of injury to your vehicle. Here are a number of the key signs you would like to observe out for:
Difficulty starting: Does your car take a short time to start? That’s commonly associated with a camshaft problem. Listen for clicking noises as you switch the key. The vehicle can also start then die. If the matter isn’t fixed, eventually, the car won’t start in the least .
Stalling: almost like issues starting, the car may have trouble idling or stall randomly , especially at lower speeds.
Reduced fuel mileage: Large decreases in fuel mileage could be a results of the P0014 code. The decrease often occurs overnight instead of a gradual decline, making it easier to note .
Noise and vibration: A camshaft problem also can cause a rough ride because the vehicle receives an improper fuel-air mix. you’ll notice your vehicle shaking, more exhaust smoke, or the engine running louder than usual.
Causes of Code P0014
There are a couple of common causes of P0014 code that would be the source of the matter , including:
The engine oil viscosity is just too high and blocking passage to the camshaft. The flow of oil to the engine must be constant, which enables it to run smoothly.
The camshaft could be lodged during a higher position, but it had been instructed by the ECM to be lowered. The ECM must have full control of the camshaft for it to function correctly.
The camshaft phaser (aka camshaft actuator) and bank 1 oil control solenoid got to be liberal to move as needed . However, once they become stuck, it results in the P0014 code.
Is Code P0014 Serious?
When a vehicle doesn’t start properly or stay running, that’s a significant problem for many people. However, whether it’s a significant problem to repair depends on what generated the code within the first place.
A faulty timing chain can cause serious engine damage. Continuing to drive your car can cause further damage and a better repair bill. Ideally, you would like to drive to your nearest mechanic to urge the matter checked out as soon as possible.
How to Fix
There are a few of strategies you’ll use to repair a code P0014 error. you’ll got to change the oil and filter, which is typically an easy DIY job if you’ve got the experience. Alternatively, it’s a cheap maintenance service at the most shops.
You may still got to reset the fault code to urge your check engine light to travel out. If the matter isn’t fixed, the sunshine will come on.
If it does, you’ll got to replace the camshaft. the problem of this procedure depends on how easily accessible the camshaft is. Mechanics will charge more depending how difficult it’s to access and complete the method .
Finally, the phasers may have to be repaired or replaced. the value and time to finish the repair vary counting on what proportion damage the components have suffered.
Overall, the P0014 code is of medium severity and deserves your attention before you are doing any long-distance driving. concentrate to the symptoms and obtain the matter fixed early to avoid further complications.
