PowertrainMedium urgency
What this code means
The intake camshaft on bank 1 is more advanced than the PCM commanded, or the VVT system isn't responding as expected. Often caused by low/dirty oil or a faulty oil control valve.
Common causes for your Hyundai
- Low or dirty engine oil (most common—change oil first)
- Failed or sludged oil control valve (OCV/VVT solenoid)
- Stretched or worn timing chain
- Stuck VVT actuator (cam phaser)
Symptoms
- Check Engine Light
- Rough idle or rattling on cold startup
- Poor fuel economy
- Reduced power
Typical fixes
- Oil change with correct viscosity oil (often resolves it)
- Clean or replace oil control valve
- Replace timing chain if stretched
- Replace cam phaser if faulty
Repair cost range
For a Hyundai, repairs for P0011 often fall between $50 and $1200, depending on the cause and whether you use OEM or aftermarket parts. Labor rates vary by location.
Known issues on Hyundai
Hyundai Theta-II and Nu GDI engines see P0011 from CVVT solenoid clogging. An oil change with 5W-20 full synthetic and solenoid screen cleaning resolves most cases.
