P0016 on a Hyundai: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can often drive a Hyundai short distances with P0016, but if it runs rough, stalls, or won't start, stop driving — a jumped timing chain can cause major engine damage.

What P0016 means on a Hyundai

On a Hyundai, P0016 means the crankshaft and camshaft position sensors on bank 1 are out of sync. Hyundai engines use the CVVT variable valve timing system, and a correlation code usually points to a stretched timing chain, a stuck oil control valve, or a faulty sensor. If the chain has jumped, the engine can be damaged.

Is P0016 common on Hyundais?

P0016 appears on Hyundai models like the Elantra, Sonata, and Tucson, often at higher mileage. The oil control valve can get clogged with sludge, and timing chains stretch over time, especially when oil changes are skipped.

Commonly reported on: Elantra, Sonata, Tucson, Santa Fe.

Check engine light on
Rough idle or stalling
Hard starting in some cases
Loss of power or poor fuel economy

Common causes

most common: Stretched timing chain
common: Clogged or stuck oil control valve
common: Worn chain tensioner or guide
less common: Faulty camshaft position sensor
less common: Low oil level or low oil pressure

Frequently asked questions

Can I keep driving my Hyundai with a P0016 code?

Short distances are usually okay if the engine runs fine. If it idles rough, stalls, or won't start, stop driving — a jumped timing chain can ruin the engine.

What causes P0016 on a Hyundai?

A stretched timing chain is the most common cause. A clogged oil control valve, worn chain tensioner, or a bad camshaft position sensor can also set this code.

How much does it cost to fix P0016 on a Hyundai?

Replacing the oil control valve runs about $100–$300. A timing chain job usually costs $1,000–$2,000, and a camshaft sensor is around $80–$200.
