Toyota RAV4’s OBD-II Trouble Code P0014 indicates Camshaft Position B – Timing Over-Advanced (Bank 1), which means that the exhaust camshaft on cylinder one is too advanced.
In this article, I will be talking about the P0014 trouble code in Toyota RAV4, its symptoms, causes, and how to fix it.
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 RAV4 P0014 Code Possible Causes
Toyota’s P0014 trouble code is generated when the vehicle’s computer detects an over-advancing or premature exhaust camshaft on bank 1.
The check engine light will be illuminated to notify drivers, and the ECU will save a P0014 code.
Here are several causes of the P0014 code in Toyota RAV4:
Bad 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 (VCT), or variable valve timing solenoid (VVT), become clogged with debris.
These are the most common symptoms that Toyota P0014 trouble codes can cause:
The Check Engine Light will illuminate, indicating an issue.
Problem with the Toyota’s starting: Is it taking too long for your Toyota to start? Camshaft problems could cause this. Listen to the clicking sound as the car starts or stops. If this is not fixed, the car may not start at all.
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 RAV4 With a P0014 Code?
It is not safe to drive a Toyota RAV4 with the P0014 trouble code. An issue with the timing of camshafts could lead to engine failure. In this case, it can be costly and time-consuming to replace the engine.
Many people become worried when their vehicle won’t turn on or isn’t responding to their commands. However, the extent of the problem will depend on the cause.
Engine damage can be caused by timing chains that aren’t working properly. Failure to bring your vehicle in for repairs can lead to additional damage and a high repair bill. It is important to contact a mechanic immediately to diagnose the problem and get it fixed.
Toyota RAV4: How To Diagnose The P0014 Code
Without the right knowledge and experience, diagnosing a Toyota RAV4 P0014 code can be difficult.
It can be difficult to achieve camshaft timing due to the complexity of some systems.
Most people can quickly identify the trouble code P0014 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 its 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. If the timing chain or timing belt is damaged, take it apart and inspect for any damage.
Toyota RAV4 P0014 Code Common Diagnosing Mistakes
A common misdiagnosis in the Toyota RAV4’s P0014 code is mistakenly believing that the timing belt or chain is defective.
Replacing a damaged device can be costly. In many cases, other issues could cause the P0014 code to appear. It is important to conduct a thorough diagnosis before you begin repairs.
Toyota RAV4’s P0114 code indicates a malfunctioning VVT/VCT system that regulates camshaft timing. Other possible causes include an incorrect camshaft position sensor or low oil levels.
Toyota RAV4 P0014 Code Repair Cost
Repairing The P0014 code in Toyota RAV4 costs between $150 and $200 in total. The labor cost is $110 while parts can be between $40 and $90 depending on the year and quality of the product.
What Repairs Can Fix The P0014 Code in Toyota RAV4?
Repairs that can fix the P0014 trouble code in Toyota RAV4 include:
Change the oil filter and add or remove excess 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 the 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 RAV4
Here is how to fix the P0014 code in Toyota RAV4:
Clearing error codes, and performing a road-test
You can extend the engine’s life by changing the oil filter and oil with engine-specific viscosity oils.
Replace or repair the wiring for the bank 1 exhaust camshaft oil valve.
Bank 1 needs to replace its exhaust camshaft oil control valve.
When replacing or fixing the timing chain, camshaft-phasers, and/or the timing chain, please refer to the service manual.
In Conclusion
Toyota RAV4’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 the 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.
