Fault code P0014 is logged when the engine control module (ECM) has detected that the exhaust camshaft is more advanced than expected. This is for bank 1 of the engine. This occurs when the ECM is unable to correct the over-advancement of the camshaft in the first bank.
There are a number of issues resulting from any camshaft that is not behaving as intended.
Camshafts are responsible for numerous engine operations. The most common of these is ensuring the correct timing of the cylinder valves. In the case of the exhaust camshaft or “B” camshaft, it is responsible for expelling exhaust fumes within the correct timing.
This type of issue is more specific to vehicles with variable valve (VVT) or camshaft timing.
As engines get more complex, the risk of these issues increases. Manufacturers like GMC, Hyundai, Kia, and Opel/Vauxhall appear to be more susceptible to these issues than others.
Other Signs of This Problem
There are several fairly noticeable indicators that will allude to improper camshaft positioning. The first of these will be the presence of the Check Engine light. It may also be flashing.
If the camshaft is stuck too far advanced, the vehicle may have difficulty starting due to improper timing.
Another telltale sign is a rough feeling from the engine at idle. The vehicle may also unexpectedly stall.
If these symptoms are present in the absence of this code, it could still be a camshaft issue. For the mirror fault code which represents this issue in bank 2, refer to P0024. For faults with the intake camshaft, see P0011 and P0021.
What Could Be The Problem?
The most notable cause of this is that the exhaust camshaft in bank 1 has advanced too far for the ECM to be able to correct it.
Oil also plays a significant role in camshaft issues. If oil quality is not up to standard, particularly if it is too thick, it can cause the passages to clog up. This can restrict the flow of oil to the camshaft-phasers, which disrupts the correct operation of VVT.
Additionally, the oil control solenoid could have some malfunction in which it is stuck open, allowing excess oil to flow. Again, this can disrupt correct VVT.
There are several fixes that can be done for this type of P0014 issue. These range from relatively simple to very complex.
The first step is to check the oil. If the oil is in any way contaminated, old, or too thick, replacing the oil can be very helpful. It is also a good idea to check and replace the oil filter. This can give more information about the problem.
If there is any damage to the oil control valve, be sure to replace this.
If there is a timing issue, be sure to replace a damaged or worn timing belt or chain. Also, check for damage in the camshaft phaser.
Ensure all the wiring to ensure it is free of damage.
Fault code P0014 represents a very serious issue. Any issue with a camshaft has the potential to cause severe damage to the engine and other expensive components.
If you notice any of these symptoms, be sure to stop driving immediately. It is best to have this issue resolved as soon as possible.
