P0014 Toyota Prius Trouble Code Definition
P0014 trouble code in Toyota Prius is defined as Camshaft Position Sensor B Timing Over-Advanced or System Performance (Bank 1).
What Does The P0014 Code Mean In Toyota Prius?
The P0014 trouble code in Toyota Prius means that the vehicle’s computer has detected a camshaft position on cylinder one to be over-advanced.
This code can be found alongside P0011, P0012, or P0013.
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 Prius P0014 Code Possible Causes
Toyota Prius’s P0014 trouble code is generated when the vehicle computer detects that bank 1’s exhaust camshaft is ahead or over-advancing.
This will cause a check engine warning light to illuminate and an ECU to store a P0014 Code.
Toyota Prius may issue the P0014 code for a variety of reasons:
- Improper Camshaft Timing
- Defective Camshaft Timing Control Solenoid
- Variable camshaft tuning failure (VVT) and variable valve timing failure (VCT).
- Oil lines of the variable camshaft tun (VCT), and variable valve timing (VVT), solenoid get clogged up with debris.
- Low engine oil
- Oil Pressure at a Low Level
- Defective Camshaft Position Sensor
- A neglected crankshaft position sensor
- The wiring is not working properly
- Defective timing system or timing belt
- Defective Timing Tensioner
Toyota Prius 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. If this is not fixed, the car may not start at all.
- Stalling: Your vehicle might experience similar issues to problems starting.
- Significantly Decreasing Fuel Economy with the P0014 Code: This code can cause a sudden decrease in fuel economy. It is easier to spot.
- 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 Prius With a P0014 Code?
It is not safe to drive a Toyota Prius 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.
How To Diagnose The P0014 Code In a Toyota Prius
- 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 Prius P0014 Code: Common Diagnosing Mistakes
A common misdiagnosis in Toyota Prius’s P0014 code is to mistakenly believe 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‘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.
How Much Does It Cost To Repair P0014 Code In Toyota Prius
It costs $155 to repair the P0014 code in Toyota Prius. Parts cost $55 while labor costs $100.
What Repairs Can Fix The P0014 Code in Toyota Prius?
- Make sure to add or take out excess engine oil, and that you change the oil filter.
- Cleaning the oil lines of variable camshaft tuning systems (VCT), or variable timing (VVT), systems.
- Clean or replace variable camshaft tun (VCT), or variable timing (VVT), solenoid.
- Replace the timing belt/chain
- Replace the solenoid at the camshaft Timing Control Valve
- Adjusting the camshaft position sensor
- Replace the crankshaft position sensors
- Repair any defective wiring
How To Fix The P0014 Code In Toyota Prius
- 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, or camshaft-phasers, please refer to the service manual.
Toyota Prius’s code P0014 indicates a timing issue in the camshaft. The cause for this is improper camshaft position timing. It is important to correct this immediately.
You can also cause it by insufficient motor oil or a malfunctioning camshaft sensor.
If you are not sure about fixing the problem by yourself, take your car to a mechanic shop.
