P0011 on a Hyundai Elantra
P0011 means camshaft Position Timing Over-Advanced (Bank 1). On the Elantra, a few causes come up far more than others.
What P0011 usually means on a Elantra
P0011 on the Elantra means the bank 1 intake camshaft is over-advanced or not responding as commanded, a fault in Hyundai's CVVT variable valve timing. On these engines the leading causes are oil-related: a stuck or dirty oil control valve, low or dirty engine oil, or, at higher mileage, timing-chain wear. CVVT relies on clean oil pressure to move the cam, so neglected oil changes are a common contributor. Symptoms often include a rough idle, hesitation, and sometimes a rattle at startup.
Most common causes on the Elantra
- Stuck or dirty oil control valve
The OCV (also called the CVVT solenoid) is a frequent cause; sludge or debris keeps it from regulating oil to the cam actuator.
- Low or dirty engine oil
CVVT needs clean oil at proper level and pressure; overdue changes commonly set this code.
- Timing-chain wear or stretch
At higher mileage a stretched chain or worn guides throws cam timing off enough to trigger P0011.
- Faulty camshaft actuator
A worn cam phaser cannot hold the commanded position.
What P0011 costs to fix on a Elantra
Start cheap: an oil change and a new oil control valve is a low-hundreds repair and resolves many of these. If the timing chain is at fault, the job is much larger because of the labor to access and replace it, running into four figures. Confirming the oil path and OCV first can save a great deal.
Fixing it
Change the oil and test or replace the oil control valve before assuming a timing-chain job; on these CVVT engines a dirty OCV or neglected oil is a common and inexpensive cause of P0011.

Year, engine and mileage change the answer. Start a case and Redline weighs these causes against what your car shows, then names the check that would settle it.
Elantra owners also ask
Is P0011 on my Elantra a timing-chain problem?
It can be at higher mileage, but more often it is a dirty or stuck oil control valve or simply low or dirty oil. Try an oil change and OCV service first, and only investigate the timing chain if the code persists or you hear chain rattle.
Does the oil control valve need replacing or just cleaning?
Sometimes cleaning the OCV and its screen restores function, but if it is worn or sticking electrically it should be replaced. It is an inexpensive part, so many shops simply replace it once it is out and the oil is refreshed.
