P0014 Toyota 4Runner Code: Camshaft Position Timing Over-Advanced or System Performance Bank 1

The P0014 code on a Toyota 4Runner is an OBD-II trouble code that indicates Camshaft Position “B” – Timing Over-Advanced or System Performance (Bank 1), meaning the exhaust camshaft on the first cylinder is over-advancing.

In this article, I will be explaining the P0014 trouble code in Toyota 4Runner, what causes it, how to fix it, and how much it will cost.

P0014 Toyota 4Runner Trouble Code Definition

P0014 Toyota 4Runner Code Camshaft Position Timing Over-Advanced or System Performance Bank 1

P0014 is a generic trouble code in Toyota 4Runner that stands for Camshaft Position Sensor B Timing Over-Advanced or System Performance (Bank 1).

What Does The P0014 Code Mean In Toyota 4Runner?

The P0014 trouble code on a Toyota 4Runner is an internal generic trouble code that indicates an excessive camshaft position (CMP) timing advance.

It can be seen alongside related codes like P0011, P0012, and P0013.

Bank 1 refers to the region in the engine containing the first cylinder, while position “B” refers to an exhaust camshaft which, depending on your vehicle model and make/model, may be located either at the rear or right side from a driver’s perspective.

Toyota 4Runner: Possible Causes of The P0014 Code

The P0014 Toyota 4Runner trouble code is displayed when the vehicle’s computer detects that the exhaust camshaft on bank 1 is progressing too quickly, or ahead of schedule.

Therefore, a check engine light will illuminate to alert drivers and the ECU will store a P0014 code.

There are multiple causes that could result in the P0014 code being displayed on your Toyota 4Runner:

  • Bad Camshaft timing sensor
  • Defective Camshaft Timing Control Solenoid
  • Variable camshaft tuning (VVT) or variable valve timing (VCT) that has not worked.
  • Oil lines of variable camshaft tuning (VCT) or variable valve timing (VVTOpens in a new tab.
  • Engine Oil LowOpens in a new tab.
  • Oil Pressure LowOpens in a new tab.
  • Defective Camshaft Position Sensor
  • Neglected Crankshaft Position Sensor
  • Damaged wiring
  • Defective timing chain or timing belt.
  • Defective Timing Tensioner

Toyota 4Runner: Common Symptoms of the P0014 Code?

As with any other trouble code, the early detection of the P0014 code is essential.

Here are common symptoms associated with the P0014 trouble code in Toyota 4Runner:

  • The Check Engine Light illuminates, signaling an issue.
  • Starting Issue: This could be due to camshaft issues. As you turn the key, listen for clicking sounds as the car starts and then stops; eventually, if not addressed, it may not start at all.
  • Stalling: Similar to problems with starting, your vehicle may experience difficulty idling or randomly stall at lower speeds.
  • P0014 Code Causes Significant Decreasing Fuel Economy: The P0014 code may cause abrupt decreases in fuel economy, making it easier to detect.
  • Noise and Vibration from the Engine: A camshaft issue can lead to a rough ride due to an incorrect fuel-air mix. You may feel your vehicle shaking, emitting more exhaust smoke, or running louder than normal.
  • Vehicles will fail emissions tests due to engine emissions.

Is It Safe To Drive a Toyota 4Runner With a P0014 Code?

No, it is never safe to drive a Toyota 4Runner with the P0014 trouble code without first diagnosing the issue. Neglecting camshaft timing could potentially result in complete engine failure – in which case replacement of that engine could become costly and time-consuming.

People often become concerned when their vehicle won’t start or seems unresponsive. However, the true extent of the issue depends on what caused the code in the first place.

Timing chains that malfunction can cause significant engine damage. Neglecting to take your car in for repairs could result in further harm and an expensive repair bill, so it is best to get to a mechanic as soon as possible to have the problem diagnosed and addressed.

How To Diagnose The P0014 Code In a Toyota 4Runner

Diagnosing a P0014 trouble code in Toyota 4Runner can be challenging without the right expertise and insight.

Due to the intricate nature of some systems, it may be difficult to precisely time camshaft timing without the correct tools and expertise.

Here is how to diagnose the P0014 code in Toyota 4Runner:

  • Connect an OBD2 scanner and check for any trouble codes that could be causing the P0014 code. If you locate any related to either the crankshaft position sensor or the camshaft position sensorOpens in a new tab.
  • Check your engine oil level to make sure it is sufficient. If it is low, add more or replace both the oil and filter. Clear away any P0014 error codes and try again.
  • Examine your service manual and oil filler cap to detect signs of sludge inside the engine. If there are, your engine oil may be very old and clogging up its lines to the variable valve timing (VVT) or variable camshaft tuning (VCT) engine control valve. In such cases, it may be necessary to switch both types of oils and clean both components separately.
  • Test the variable valve timing (VVTOpens in a new tab.
  • If possible, take the variable camshaft tuning (VCT) control valve solenoid and clean its oil passages using compressed air and a suitable cleaning solution.
  • Verify the camshaft and crankshaft position sensors to make sure they are sending accurate signals.
  • Manually verify the engine camshaft timing by consulting your owner’s manual for instructions on how to do so in your specific engine. If the timing belt or chain is damaged, disassemble it and inspect for damage.

Toyota 4Runner: Common Mistakes When Diagnosing The P0014 Code

Toyota 4Runner drivers often misdiagnose the P0014 code as a sign that their timing chain or belt is damaged, when in fact this could be an entirely preventable error.

Replacement can be expensive, and in many cases, the P0014 code could be indicative of another underlying issue; thus, conducting a comprehensive diagnosis before beginning repairs is essential for accurate outcomes.

P0114 in Toyota 4Runners typically indicates a problem with the VVT or VCT system, which regulates camshaft timing. Other potential causes could include an errant camshaft position sensor or low oil levels.

How Much Does It Cost To Repair P0014 Code In Toyota 4Runner?

Repairing the P0014 code in Toyota 4Runner costs $35.01 for the exhaust camshaft position sensor and $90 for labor, totaling $125.01.

What Repairs Can Fix The P0014 Code in Toyota 4Runner?

Here are all the repairs that can fix the P0014 code in Toyota 4Runner:

  • Add or drain excess engine oil and replace the oil filter as necessary.
  • Cleaning oil lines associated with variable camshaft tuning (VCT) or variable valve timing (VVT) systems.
  • Cleaning or replacing the variable camshaft tuning (VCT) or variable valve timing (VVT) solenoid may be necessary.
  • Replacement of the timing belt or chain
  • Replace the camshaft timing control valve solenoid.
  • Adjust the Camshaft Position Sensor
  • Replace the crankshaft position sensor
  • Repair any defective wiring.

How To Fix The P0014 Code In Toyota 4Runner

Here is how to fix the P0014 code in Toyota 4Runner:

  • Clearing error codes and performing a road test
  • By replacing the oil and filterOpens in a new tab.
  • Repair or replace the wiring to the bank 1 exhaust camshaft oil control valve.
  • Bank 1 requires replacing its exhaust camshaft oil control valve.
  • Follow the service manual’s instructions when repairing or replacing the timing chain and camshaft-phasers.

In Conclusion

Toyota 4Runner’s P0014 code indicates a timing issue with the camshaft. This could be caused by incorrect camshaft timing and should be addressed promptly to avoid costly repair bills in the future.

Yet it could also be caused by something as minor as insufficient engine oil or a malfunctioning camshaft position sensor – both of which are usually fixable for under $200.

If you are uncertain of your ability to fix this problem yourself, contact a knowledgeable mechanic right away for assistance.
