P0014: OBD-2 error code interpretation and solutions

Enter the error code and car brand

Vehicle engine and/or automatic transmission

Code: P0014 - "B" Camshaft Position - Timing Over-Advanced or System Performance Bank 1

Error P0014 is a common OBD-2 code applicable to cars such as Toyota, BMW, Kia, Mercedes-Benz, Ford, Volkswagen, Skoda, Nissan, Renault, and others. It indicates that the engine control module has detected that the exhaust camshaft for bank 1 is positioned more advanced than expected by the ECU. This condition arises when there is early or delayed synchronization of the camshaft position.

Causes of OBD P0014

The P0014 code can appear for several reasons:

The exhaust camshaft for bank 1 is excessively advanced when the engine control module is out of the delayed synchronization positions.
A thick oil consistency may cause clogging in the channels, restricting oil flow to the camshaft phasers and back.
The camshaft phaser may get stuck in the extended position of the camshaft.
The oil control solenoid for the exhaust camshaft on bank 1 may be shorted in the open position.

Symptoms of Error P0014

Here are some of the most common symptoms that might indicate a problem with your car and the P0014 code:

The first sign of the problem will be the illumination of the check engine light.
You might feel that engine performance is impaired, which could happen if the camshaft is stuck too far ahead.
Fuel efficiency or mileage may decrease due to incorrect camshaft positioning, which affects fuel economy.
Depending on the camshaft position, engine operation may become uneven or lead to stalling.
If your car undergoes an emissions test, it might fail to meet standards, potentially resulting in an unsuccessful test.

How to Diagnose DTC P0014?

There are several steps that a mechanic will take when checking and confirming that the P0014 code is indeed detected in the vehicle:

The mechanic should perform a visual inspection of the wiring, connectors, and/or solenoid for any obvious issues with the OCV (Oil Control Valve) for the exhaust camshaft on bank 1.
Check the engine oil level and condition to ensure it is full and of the correct viscosity.
Scan and document any engine codes, reviewing the freeze frame data to determine when the code was set.
The next step is to clear all codes. This allows the mechanic to check whether the code reappears, indicating an ongoing issue.
They will monitor time data by deactivating the OCV for the exhaust camshaft on bank 1 to see if timing changes. Any change will indicate that the valve is working, and the issue is likely with the wiring or ECM.
They will then perform the manufacturer-specific tests for the P0014 code and fix it if necessary.

How to Avoid Common Mistakes with OBD Code P0014?

Here are some common mistakes to watch out for when confirming the P0014 code:

Perform a visual inspection of the connector, solenoid, and wiring to confirm any issues with the oil control valve for the exhaust camshaft on bank 1.
Check the oil level and condition in your vehicle to ensure it is full and has the proper viscosity.
Scan and document engine codes using a popular OBD2 scanner, and review the freeze frame data to check when the code was set.
Clear all OBD2 codes, then start the engine to see if the P0014 code reappears. If it does, the issue persists.
Observe the timing data when deactivating the oil control valve for the exhaust camshaft on bank 1 to see if the timing changes. A change indicates that the valve is working, and the issue lies with the ECM or wiring.
Perform manufacturer-specific tests for accurate determination of the P0014 code and fix it as necessary.

How Serious Is Error P0014?

The P0014 code is quite serious and should be addressed if you notice any issues with your vehicle:

Engine performance may become uneven, sluggish, or difficult to start.
Fuel consumption may increase, potentially causing carbon buildup on pistons and valves.
Driving for an extended period with incorrect camshaft timing could cause valve-to-piston contact, especially if the timing chain has skipped gear teeth.

How to Fix Code P0014?

Here are some common repair methods that can fix the P0014 code:

Reset the fault codes and perform road tests.
Replace the oil and filter, using the correct oil viscosity for the engine.
Repair or replace the wiring to the oil control valve for the exhaust camshaft on bank 1.
Replace the oil control valve for the exhaust camshaft on bank 1.
Repair or replace the timing chain and camshaft phases as specified in your vehicle's maintenance guidelines.

Conclusion

If the P0014 code is not diagnosed and repaired, it could lead to serious issues with your vehicle. We recommend using this guide to properly diagnose, confirm, and fix the problem in order to clear this OBD2 trouble code correctly.
