Meaning of the P0014 OBD2 Code
Skip to the good stuff:
The technical definition of P0014 is Camshaft Position “B” Timing Over-Advanced or System Performance Bank 1. Again, it is quite a mouthful, but is simple to understand once you break the words apart.
In layman terms, P0014 is a generic engine code that refers to an advanced or over-advanced exhaust camshaft in bank 1.
Similar to other related OBD2 diagnostic trouble code, this code is mostly seen in V6, V8, or larger motors with VVT (Variable-Valve Timing). Depending on the configuration, this system utilizes sensors to monitor the timing in the intake and exhaust valves. The P0014 trouble code is significantly associated to the exhaust cam in bank 1.
What are the causes of a P0014 fault code?
Since P0014 has something to do with the position of the exhaust cam, the problem can be traced to the camshaft phaser and related components, which includes the oil control solenoid and the oil viscosity.
Yes, P01144 can be caused by dirty or sludgy motor oil. Remember that VVT-equipped motors rely on clean engine oil to adjust the cam timing. If the engine oil is dirty, it might clog up the tiny oil passages in the camshaft phasers. When this happens, the cam will be stuck to an over-advanced position, which also results in poor emissions and lethargic engine performance.
The problem can also be attributed to a shorted oil control solenoid in bank 1. This particular issue is caused by a wiring problem.
What are the symptoms of the P0014 DTC?
The main symptom is the presence of a check engine light in the console. This is followed by hard starting or the refusal to start at all. If this is the case, it means the camshaft is stuck in a far advanced position.
Here’s the most common symptoms you’ll experience with this DTC:
- Rough Idle
- Poor throttle response
- Fuel economy loss
- Failure to start
If the engine is running, you will notice poor fuel economy and rough idling. In some cases, the engine will stall depending on the position of the stuck camshaft. But whatever the case, an engine running with a check engine light and P0014 code is sure to fail the emissions test.
How much does it cost to fix a P0014 OBD2 trouble code?
The cost will vary. In most cases (or if the engine is relatively new), a simple oil change will do the trick. You can this in your own garage for not a lot of money. However, it is important not to skimp on an OEM oil filter and good quality engine oil. Modern vehicles equipped with VVT motors require fully-synthetic blend motor oil to sustain good engine performance, even over longer mileage.
Dirty oil has a tendency to produce sludge, which will block the tiny oil passages in the cam phasers. And you know this is bad news, right? Once the exhaust cam gets stuck, the P0014 OBD2 trouble code is sure to ruin your day.
But in some cases, the mechanic will need to perform a visual inspection on the valve or wiring in the bank 1 exhaust camshaft. If this is the case, replacing critical engine components will cost more money.
