P0014 Toyota Sienna Code: Camshaft Position Timing Over-Advanced or System Performance Bank 1

OBD-II Trouble Code P0014 in Toyota Sienna indicates Camshaft Position B – Timing over-Advanced or Performance (Bank 1), which means the exhaust camshaft of the first cylinder may be too advanced.

In this article, I will be talking about the P0014 trouble code in Toyota Sienna, its symptoms, causes, and how to fix it.

P0014 Toyota Sienna Trouble Code Definition

P0014 Toyota Sienna Code Camshaft Position Timing Over-Advanced or System Performance Bank 1

P0014 trouble code in Toyota Sienna is defined as Camshaft Position Sensor B Timing Over-Advanced or System Performance (Bank 1).

What Does The P0014 Code Mean In Toyota Sienna?

Toyota Sienna’s trouble code P0014 is an internal powertrain code that signals excessive camshaft positioning (CMP) timing advance.

You may see it alongside related codes like P0011, and P0012.

The location of the error is indicated by the trouble code P0014Opens in a new tab.

Bank 1 refers to the area of the engine that contains the first cylinder. Position “B”, which is an exhaust camshaft, can be found depending on vehicle model and make/model at either the rear or right side, from a driver’s perspective.

Toyota Sienna P0014 Code Possible Causes

Toyota Sienna’s ECU generates the P0014 trouble codes when it detects that the exhaust camshaft bank 1 is either over-advancing or ahead of schedule.

A check engine light will go on to alert drivers. The ECU will also store the P0014 code.

Toyota Sienna could have a number of reasons for the P0014 Code:

  • Improper Camshaft Timing
  • Defective Camshaft Timing Control Solenoid
  • Failed variable camshaft tuning or variable valve timing
  • Oil lines for variable camshaft tune (VCT) and variable valve timing solenoid (VVT) become clogged.
  • Low Oil Levels
  • Oil Pressure Low
  • Defective Camshaft Position Sensor
  • A neglected crankshaft position sensor
  • Broken wiring
  • Defective timing chains or timing belts
  • Defective Timing Tensioner

Toyota Sienna P0014 Code Common Symptoms

  • The Check Engine Light lights up, which indicates an issue.
  • Camshaft problems could be the cause of this problem. As you turn the key, listen out for clicking sounds when the car starts and stops.
  • Stalling may occur in the same way as problems with starting. Your vehicle may have difficulty idling, or stall randomly at lower speeds.
  • P0014 Code Can Cause Significant Decreasing Fuel Economy. The P0014 codes can cause sudden drops in fuel economy. This is easier to detect.
  • Noise and vibration from your Engine: A problem with the camshaft can result in a rough ride because of an improper fuel-air blend. Your vehicle might shake more than normal, emit more smoke, or be louder.
  • Emission tests for vehicles will be failed due to engine exhaust.

Is It Safe To Drive a Toyota Sienna With a P0014 Code?

It is unsafe to drive a Toyota Sienna with a P0014 trouble code without diagnosing the problem. A problem with the timing of the camshaft could cause engine failure. This can lead to expensive and lengthy repairs.

When their vehicle doesn’t respond or won’t start, many people are concerned. It all depends on what caused it.

Failure to maintain timing chains can lead to major engine damage. You should not neglect to bring your car to the mechanic for repairs. This could lead to more damage and costly repair bills.

Toyota Sienna P0014 Code: How To Diagnose

If you don’t have the right information and expertise, it can be hard to diagnose a Toyota Sienna P0014 trouble code.

Because of the complexity of many systems, it can be difficult for camshaft timing to be achieved without having the right tools and knowledge.

Anyone with basic computer skills can quickly diagnose the problem code P0014.

  1. Connect an OBD2 scanner, and look for any trouble codes that may be causing your P0014 code. It’s time for you to diagnose any problems related to the crankshaft sensor or camshaft sensor to determine if they can solve your P0014 problem.
  2. Make sure your engine oil is at the right level. Low oil levels can be corrected by adding oil or replacing both the oil filter and oil. Clear away any P0014 error codes.
  3. Check your oil filler cap and service manual for any signs of engine sludge. There may be an accumulation of engine oil in the engine’s oil lines, which could lead to clogging at the variable valve timing (VVT), or variable camshaft tune (VCT) engine control valve. You have to clean both components and change the oil.
  4. Use your diagnostic scanner to test the variable timing (VVTOpens in a new tab.
  5. As soon as possible, take out the variable camshaft tune (VCT), and control valve solenoid. Clean its oil passages with a compressed or suitable cleaning solution.
  6. To verify that the signals are accurate, check the position sensors at the crankshaft or camshaft.
  7. Check the timing of the engine camshaft by manually checking it. For instructions on how to do it in your engine, consult your owner’s manual. If the timing belt/chain is not working properly, remove it from the engine and inspect it for damage.

Toyota Sienna P0014 Code: Common Diagnosing Mistakes

The common mistake in diagnosing the Toyota Sienna P0014 code as a misdiagnosis is thinking that the timing chain or belt is defective.

Repairs can be costly and the P0014 error code may be the result of other issues. Therefore, it is crucial to perform a complete diagnosis before starting repairs.

Toyota P0114 is a sign of a malfunctioning VVT/VCT system. This regulates camshaft timing. Low oil levels or errant camshaft position sensors could also be possible causes.

How Much Does It Cost To Repair P0014 Code In Toyota Sienna

It costs $150 to repair the P0014 code in Toyota Sienna. The part costs $70 while labor costs $80.

What Repairs Can Fix The P0014 Code in Toyota Sienna?

  • You can add or remove oil from your engine and also change the oil filter.
  • Clean oil lines that are associated with variable camshaft timing (VCT) and variable valve timing (VVT).
  • Clean the solenoid for variable camshaft timing (VCT), and replace it.
  • Repair of the timing belt/chain
  • Change the solenoid for the camshaft timing valve solenoid
  • Set the Camshaft Position Sensor
  • Replace the crankshaft position sensor
  • Fix any defective wiring

How To Fix The P0014 Code In Toyota Sienna

  • Clearing error codes and performing road tests
  • It is possible to improve engine performance and prolong engine life by replacing the oil and filter with engine-specific viscosity oil.
  • Replace the wiring of the bank 1 exhaust camshaft oil control valve.
  • Bank 1 must replace its exhaust camshaft oil valve.
  • For repairs or replacements of the timing chain or camshaft phasers, refer to the manual.

In Conclusion

Toyota Sienna’s P0014 code is indicative of a timing issue in the camshaft. The cause for this is the incorrect timing of the camshaft. If this happens, you should fix it immediately.

However, it could also be caused by insufficient oil or a malfunctioning sensor at the camshaft position – both of which can usually be fixed for less than $200.

For assistance, call a skilled mechanic immediately if you are not sure you can fix this problem.
