P0014 Toyota Yaris Trouble Code Definition
P0014 trouble code in Toyota Yaris is defined as Camshaft Position Sensor B Timing Over-Advanced or System Performance (Bank 1).
What Does The P0014 Code Mean In Toyota Yaris?
P0014 trouble code in Toyota Yaris is an internal code that indicates excessive camshaft position (CMP) timing advance.
This code is often accompanied by P0011, P0012, or P0013 codes.
The trouble code P0014
indicates where the error occurred.
Bank 1 is the area in the engine that houses the first cylinder. Position “B” refers to an exhaust camshaft. This can, depending on the vehicle make/model, be located either at the rear or right from the driver’s perspective.
The P0014 trouble code indicates the camshaft has been over-advancing. This means it is exceeding a threshold set forth by the Engine Control Module. It may be advancing or slowing down its timing.
Toyota Yaris P0014 Code Possible Causes
Toyota Yaris’s P0014 trouble code is generated when the vehicle’s computer detects an over-advancing exhaust camshaft on bank 1.
The check engine light will be illuminated to notify drivers, and the ECU will save a P0014 code.
Toyota Yaris’s P0014 code could be triggered by several things:
- Improper Camshaft Timing
- Defective Camshaft Timing Control Solenoid
- Variable camshaft tuning (VVT), or variable valve timing (VCT), fails
- The oil lines for the variable camshaft timing (VVT
), or variable valve tuning (VCT), solenoid, become clogged with debris. - Low Engine Oil
- Oil Pressure Low
- Defective Camshaft Position Sensor
- A neglected crankshaft position sensor
- Fix broken wiring
- Defective timing belt or timing chain
- Defective Timing Tensioner
Toyota Yaris P0014 Code Common Symptoms
- The Check Engine Light will illuminate, indicating an issue.
- Problems with the camshaft could cause this to occur. Listen to the clicking sound as the car starts or stops while you turn the key.
- Stalling: Your vehicle might experience similar issues to problems starting.
- P0014 Code May Cause Significant Decreasing Fuel Economy. It is possible for the P0014 code to cause a sudden decrease in fuel economy. This makes it easier to identify.
- Noise and vibration from the Engine: An incorrect fuel-air mixture can lead to a rough ride. Your vehicle may shake, emit more exhaust smoke, or run louder than usual.
- Engine emissions can cause vehicles to fail emission tests.
Is It Safe To Drive a Toyota Yaris With a P0014 Code?
It is dangerous to drive a Toyota Yaris that has the trouble code P0014 without first diagnosing it. Neglecting a problem with camshaft timing can cause an engine to fail, which could be expensive and time-consuming.
People are often concerned when their vehicle stops responding or doesn’t start. The cause of the problem is what determines the severity.
Major engine damage can result from timing chains that fail. Neglecting to take the car to a mechanic for repairs could cause additional harm and expensive repair bills.
Toyota Yaris P0014 Code: How To Diagnose
Identifying the P0014 trouble code in Toyota Yaris is difficult without the right knowledge and experience.
It can be difficult to achieve camshaft timing due to the complexity of some systems.
Most people can quickly identify the P0014 problem code with some basic knowledge.
- Use an OBD2 scanner to search for trouble codes that might be causing the P0014 error. You should look for any trouble codes that are related to the crankshaft position sensor and camshaft position sensors to resolve the P0014 code.
- To ensure that your engine oil is sufficient, check the level. Add oil to your engine oil level or replace the filter. Clear out any P0014 error codes, and then try again.
- To check for sludge in the engine, take a look at your service manual and oil cap. You may have engine oil that is very old. This could be clogging the oil lines to the variable camshaft tuning or VVT engine control valves. It may be necessary to change both types of oil and clean both components.
- Your diagnostic scanner can test the variable valve timing (VVT), or variable camshaft tune (VCT), solenoid. To test whether the VCT solenoid is moving, perform an output test. You can experiment with 12v+ and ground if you are familiar with car electrical systems.
- Remove the variable camshaft tuning control valve solenoid (VCT) and clean the oil passages with compressed air and a suitable cleaning agent.
- To confirm that they send accurate signals, verify the position sensors on the crankshaft and camshaft.
- You can manually check the timing of your engine’s camshaft. Refer to your owner’s guide for details on how to do this in your engine. Inspect the timing chain or timing belt for damage.
Toyota Yaris P0014 Code: Common Diagnosing Mistakes
One common error in the Toyota Yaris’s P0014 code is assuming that the timing chain/belt is defective.
Replacements can be expensive and could also be caused by other problems. To ensure accurate results, it is vital to complete a thorough diagnosis prior to beginning repairs.
Toyota‘s P0114 signifies a malfunctioning or damaged VVT or VCT system. These systems regulate camshaft timing. There are other possible causes, such as an error in the camshaft position sensor and low oil levels.
How Much Does It Cost To Repair P0014 Code In Toyota Yaris
Repairing the P0014 code in Toyota Yaris costs $170. The part costs $70 while labor costs $100.
What Repairs Can Fix The P0014 Code in Toyota Yaris?
- Change the oil filter and add or remove engine oil.
- Clean the oil lines for variable camshaft tuning (VCT), or variable valve timings (VVT) systems.
- Replace or clean the variable camshaft tuning solenoid (VCT), or variable valve timing solenoid (VVT).
- Replacing the timing chain or belt
- Replacing the solenoid of the camshaft timing control valve
- The Camshaft Position Sensor can be adjusted
- Replace the crankshaft position sensor
- Any defective wiring can be repaired
How To Fix The P0014 Code In Toyota Yaris
- Clearing error codes & performing a road test
- To ensure maximum performance and extended engine life, change the oil and filter to engine-specific viscosity.
- Replace the wiring to the bank1 exhaust camshaft oil controller valve.
- Bank 1 will need to change its exhaust camshaft oil regulator valve.
- When changing the timing chain or the camshaft-phasers, be sure to follow the instructions in the service manual.
In Conclusion
Toyota Yaris’s P0014 code indicates that there is a timing problem with the camshaft. The problem could be due to improper timing of the camshaft. This should be fixed immediately or you will be charged a high repair bill.
It can also be caused simply by insufficient engine oil, or malfunctioning camshaft position sensors – both of these are typically repairable for less than $200.
You can contact a qualified mechanic right away if you are unsure of your ability to solve the problem.
