Dirty Oil: If the oil and/or oil filter haven’t been changed in a long time, sometimes it can cause the camshaft actuator to clog up with sludge.If oil flow slows down enough to throw the p0014 code, It’s likely low enough to lock up the engine. The oil level needs to be low enough to lower the engine’s oil pressure (dangerously low). Low Oil: The most common cause of P0014 is low oil.There are three ways that it can cause P0014: The first thing you should do is check your Impala’s oil. Here are the most common causes, presented in order from the easiest thing to check to the most difficult: Engine Oil Here are the most common causes of the P0014 code in your Chevy Impala. Hard to Start– With the timing too far advanced, it won’t be easy to start the motor, especially when it is warm.Service Engine Soon Light– Most of the time, you’ll be able to feel or see one of the above symptoms, but if you can’t, the check engine light will come on and let you know something is wrong.Lost Power– Your truck’s engine will not be able to produce as much power this is because the cam profile will not allow it to run a performance power curve when you need more power.Decreased Gas Mileage– Now that your Impala’s engine can no longer adjust its cam timing on the fly, it will no longer be able to produce optimum combustion, which causes poor economy.A rattling sound can also indicate the timing chain jumped a tooth. Rattling Sound– You may hear the camshaft actuator rattling at idle speed since it’s not where it’s supposed to be.Poor Idle Quality– If the “B” camshaft actuator fails while it is too far advanced, it’ll idle roughly.Here are some of the typical symptoms of P0014 in the Chevy Impala: When the cam timing is off, it can cause some issues with the motor. It’s usually the cylinder head closer to the front of the engine. You’ll need to look up which side is bank 1. If your Impala has an inline engine, you don’t need to concern yourself with this.īut, if your Impala has a “V” engine, it’ll have two cylinder heads. Bank 1īank one is the side of the engine with the first cylinder. Here’s a detailed write-up on exactly how VVT works if you’re interested in learning more. Some simpler systems change the cam timing, while others change cam profiles entirely. They are hydraulic, which means that they use the vehicle’s engine oil to change the intake valve timing. Valve timing control methods can be quite different for every engine, even from the same manufacturer, but the basics are the same.Ĭamshaft actuators or phasers change how long the intake and exhaust valves stay open. When this happens, your Chevy Impala will store trouble code P0014. Sometimes, the system will get stuck in an over-advanced position. It can advance or retard the timing at will. VVT allows an engine to act as though it has different camshaft profiles at different RPMs this is great for both power and fuel economy. Adjusting the camshaft timing allows an engine to have a better power curve and better fuel economy (the automotive equivalent of having your cake and eating it too).ĭepending on the vehicle, the “B” camshaft is the exhaust, right or rear camshaft. “B” Camshaft PositionĮngines equipped with VVT use camshaft actuators (they’re often called phasers) to adjust the position of the cam. Here it is separated into its three main pieces, with a quick explanation of each. The technical definition of P0014 for the Impala is “B” Camshaft Position Timing Over Advanced or System Performance (Bank 1). Not usually, but in rare cases, the underlying causes can damage the engine.

P0014 means that the camshaft position is too far advanced from where it should be in relation to normal operating specs.īefore doing anything, check your Impala’s oil level. VVT adjusts the position of the camshaft(s) to maximize the combustion efficiency of the motor. P0014 is a relatively common trouble code for vehicles that have Variable Valve Timing (VVT).
