Exhaust Camshaft Timing Over-Advanced or System Performance Bank 1
The engine computer sees the exhaust camshaft on bank 1 in the wrong position. This is often caused by low or incorrect oil, a faulty variable timing solenoid, or a mechanical timing problem.
You may be able to drive a short distance, but continued driving can cause poor running and possible engine damage if timing is incorrect. Avoid hard acceleration and fix it as soon as possible.
P0014 means the PCM has detected that the exhaust camshaft timing on bank 1 is more advanced than commanded, or that the variable valve timing system is not responding correctly. Bank 1 is the side of the engine with cylinder 1. The fault can be caused by oil supply problems, a failed VVT control component, or incorrect mechanical cam timing.
Bank 1 is the side of the engine that contains cylinder 1. On inline engines, it refers to the only cylinder bank.
Yes. Low oil level or oil that is too thick, too thin, dirty, or incorrect for the engine can prevent the VVT system from controlling cam timing properly.
Sometimes. If the code is caused by low oil, dirty oil, sludge, or incorrect oil viscosity, an oil and filter change may correct it. If a solenoid, actuator, or timing chain has failed, more repairs will be needed.
Yes. It can cause poor performance, stalling, and possible engine damage if the cam timing is mechanically incorrect or the timing chain is worn.
On many vehicles, yes, if the solenoid is easy to access and you have basic tools. Mechanical timing diagnosis and timing chain work are more advanced repairs.
