P0014 on Hyundai: How to Diagnose & Fix
Exhaust Camshaft Position Timing - Over-Advanced (Bank 1)

P0014 on Hyundai by model: symptoms, diagnosis and fix
The Continuous Variable Valve Timing (CVVT) actuator and its associated oil control valve (OCV) on the Santa Fe's Theta II engine can fail, causing rough idle, poor fuel economy, and check engine lights. The OCV gets clogged with sludge from extended oil change intervals, and the CVVT actuator's internal components wear out. This issue can also trigger timing-related fault codes and affect emissions.
Common Symptoms
- Check engine light
- Rough idle
- Poor fuel economy
- Rattling noise on startup
- Hesitation on acceleration
How to Fix
Replace the CVVT actuator (camshaft phaser) and the oil control valve. Clean the oil passages feeding the VVT system. Switch to a high-quality full synthetic oil and maintain strict oil change intervals (5,000 miles or less). In some cases, cleaning the OCV with throttle body cleaner can restore function temporarily, but replacement is the permanent fix.

On the Sonata, P0011 (Intake Camshaft Timing Over-Advanced, Bank 1) is set when the CVVT phasing runs further advanced than commanded. The most common Sonata cause is a failed/clogged intake Oil Control Valve (OCV/VVT solenoid) — the CVVT system uses oil pressure metered by the OCV to phase the cam, so a sticking solenoid or contaminated oil passages drive the cam over-advanced. Low oil level, wrong viscosity, or dirty oil commonly cause or worsen it; a displaced timing chain is a more severe possibility. A useful field test is swapping the intake and exhaust OCVs (identical, one bolt each): if the code migrates to P0014, the moved OCV is the faulty part.
Common Symptoms
- Check engine light
- Rough idle
- Loss of acceleration/power
- Hesitation or stalling at idle
- Reduced fuel economy
How to Fix
Verify oil level, condition, and correct viscosity first — top up/change oil if degraded. Test the intake OCV (coil resistance ~6.8-8.0 ohms at 68°F) and swap intake/exhaust OCVs to confirm; replace the failed OCV. Clean the OCV oil-feed screen/passages. If timing components are displaced, inspect and correct the timing chain.

Frequently asked questions
What does P0014 mean on a Hyundai?
P0014 stands for "Exhaust Camshaft Position Timing - Over-Advanced (Bank 1)." P0014 means the exhaust camshaft on bank 1 is timed too far advanced — the variable valve timing (VVT) system has moved the cam beyond the position the computer commanded, or it's stuck in an over-advanced position. The engine uses VVT to rotate the camshaft and optimize valve timing for power, economy, and emissions; the computer compares the commanded cam position to the actual reading from the cam sensor and flags this code when they don't agree. Common results are rough idle, reduced power, poor fuel economy, or a rattle at start-up. Oil flow and the VVT actuator are the usual suspects. On Hyundai it is documented across 2 models: Santa Fe, Sonata.
What are the most common causes of P0014?
The most common causes of P0014 are: Low or dirty engine oil restricting VVT operation, Stuck or failed camshaft oil control valve (VVT solenoid), Clogged VVT solenoid screen or oil passages, Faulty camshaft phaser/actuator, Wiring or connector fault at the oil control valve, Stretched timing chain or jumped timing, Camshaft position sensor fault giving incorrect reading. The specific cause varies by vehicle.
How much does it cost to fix P0014 on a Hyundai?
Published repair estimates on Hyundai range from $120 to $900 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
