P0017 on Hyundai by model: symptoms, diagnosis and fix
The 5.0L Tau GDI V8 in the Equus develops a timing chain rattle on cold start that lasts 1-5 seconds before oil pressure builds and the hydraulic tensioners take up chain slack. The issue is caused by the hydraulic chain tensioners bleeding down oil overnight, allowing chain slack at startup. While the rattle typically goes away quickly, prolonged operation with rattling chains can cause chain guide wear and eventual timing chain stretch. Extended oil change intervals (beyond 5,000 miles) exacerbate the issue.
Common Symptoms
- Rattling or clattering noise for 1-5 seconds on cold start
- Noise comes from front of engine (timing cover area)
- Noise disappears after engine warms up
- Rattle worsens in cold weather
- Check engine light with cam/crank correlation codes (advanced wear)
How to Fix
Change oil every 5,000 miles (not 7,500 as recommended in some manuals) with 5W-30 synthetic that maintains viscosity at cold temperatures. If the rattle persists beyond 3-5 seconds, replace the primary timing chain tensioners with updated Hyundai parts. The Tau V8 uses four timing chains (two primary, two secondary) — inspect all tensioners and guides during replacement. Some owners install one-way check valve oil drain back fittings to prevent tensioner bleed-down.

Owner tips & cautions
- TipUse a quality 5W-30 full synthetic oil (Mobil 1, Pennzoil Ultra Platinum) and change every 5,000 miles — good oil prevents tensioner bleed-down and chain wear
- TipIf cold start rattle lasts more than 5 seconds, have the tensioners inspected immediately — prolonged rattle causes chain guide wear that turns a $1,000 repair into a $3,000 one
- WarningDo not extend oil change intervals beyond 5,000 miles on the Tau V8 — the GDI system dilutes oil with fuel, reducing its ability to maintain hydraulic tensioner pressure
The Tiburon Beta and Delta engines use a timing belt with a hydraulic tensioner that can fail, causing the belt to lose tension and potentially jump timing. Both the 2.0L Beta engine (1997-2001) and the 2.7L Delta V6 (2003-2008) are interference engines, meaning a jumped or broken timing belt causes catastrophic valve-to-piston contact. The tensioner bearing can also seize, causing belt wear and failure. Replacement at the recommended 60,000-mile interval is critical.
Common Symptoms
- Ticking or squealing from timing cover area
- Engine vibration at idle
- Check engine light with timing-related codes
- Sudden engine failure if belt jumps
- Rattling on cold start

The 3.5L Sigma V6 engine in the XG350 uses a timing belt with a hydraulic tensioner that can fail, allowing the belt to lose tension. The tensioner bearing can seize or the hydraulic damper can leak, both leading to belt slack and potential timing jump. The Sigma V6 is an interference engine, so a timing belt failure or jump causes catastrophic engine damage. Hyundai recommends timing belt replacement at 60,000-mile intervals, but many XG350 owners defer this service due to cost.
Common Symptoms
- Squealing or chirping from timing cover area
- Engine vibration and rough idle
- Check engine light with timing codes
- Ticking noise from front of engine
- Sudden engine failure if belt jumps or breaks

MD-generation Elantras with the 1.8L Nu engine develop a distinct two-to-five second rattle or 'diesel' clatter on cold start-up as the hydraulic timing chain tensioner bleeds down overnight and the plastic chain guides wear and become brittle. Early on the noise is only at start-up and quiets once oil pressure builds. As the guides crack and shed material the chain slaps continuously, cam timing drifts, and in the worst cases the chain jumps teeth on the sprocket, producing a crank-no-start and, on this interference engine, valve-to-piston contact. Forum reports consistently note that replacing the tensioner alone does not cure the noise once the guides and sprockets are worn - the whole timing set is needed. The condition is aggravated by extended oil-change intervals and by the low oil level that the same 1.8L Nu is prone to, and is separate from the connecting-rod bearing knock this engine is also known for.
Common Symptoms
- Rattle or clatter for a few seconds on cold start-up
- Continuous chain slap or whine at idle as wear progresses
- Check engine light with cam/crank correlation codes
- Rough running or reduced power
- Crank but no start after the chain jumps teeth
How to Fix
Diagnose by listening at cold start after the car has sat overnight, then verify with a live-data cam/crank correlation reading and by inspecting the guides through the timing cover. The real fix is a complete timing set - chain, both guides, tensioner arm, hydraulic tensioner and, where worn, the sprockets - not a tensioner alone. There is no recall for this. Use only a filter meeting Hyundai's anti-drainback specification (Hyundai has published guidance that non-conforming filters worsen start-up noise) and shorten the oil-change interval to roughly 5,000 miles. If the chain has already skipped, a compression or leak-down test must be done before rebuilding the timing set, because bent valves are likely.

Frequently asked questions
What does P0017 mean on a Hyundai?
P0017 stands for "Crankshaft/Camshaft Position Correlation - Bank 1 Sensor B." This code means the engine computer has detected that the crankshaft and the Bank 1 'B' camshaft (typically the exhaust camshaft) are out of their proper timing relationship with each other. The computer compares the crankshaft position signal to the camshaft position signal, and when they don't line up within the allowed window, it sets this correlation code. This usually points to mechanical timing being off, most often from a stretched or worn timing chain, a slipped or stuck variable valve timing phaser, or a tensioner problem. You may notice rough running, low power, rattling at startup, or a no-start, and it should be addressed promptly to avoid valve-to-piston contact on some engines. On Hyundai it is documented across 4 models: Equus, Tiburon, XG350, Elantra.
What are the most common causes of P0017?
The most common causes of P0017 are: Stretched or worn timing chain, Worn or failed timing chain tensioner or guides, Stuck or faulty variable valve timing (VVT) cam phaser, Faulty VVT oil control/solenoid valve, Low or dirty engine oil affecting phaser operation, Faulty camshaft or crankshaft position sensor, Timing chain jumped a tooth or incorrect timing after service, Damaged reluctor (tone) ring. The specific cause varies by vehicle.
How much does it cost to fix P0017 on a Hyundai?
Published repair estimates on Hyundai range from $100 to $2,500 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.
