P0019 on Hyundai by model: symptoms, diagnosis and fix
The 3.3L and 3.8L Lambda V6 engines in the Azera use timing chains with hydraulic tensioners that can fail due to oil pressure loss or internal wear. The tensioner relies on consistent oil pressure to maintain chain tension, and low oil levels or degraded oil can cause the tensioner to lose pressure, resulting in chain slack and noise. In severe cases, the chain can jump timing, causing valve-to-piston contact on these interference engines. Regular oil changes and maintaining proper oil levels are critical.
Common Symptoms
- Rattling or chain noise on cold start
- Check engine light with timing codes
- Rough idle
- Reduced engine power
- Engine noise increases with RPM
How to Fix
Diagnose the concern by verifying oil level/condition, scanning for cam/crank correlation codes such as P0016-P0019, and listening for front cover timing chain rattle on cold start; if noise or correlation faults are present, remove the front timing cover and inspect the primary/secondary chains, hydraulic tensioners, guides, and cam phasers/CVVT components for wear or slack. Repair typically involves replacing the timing chain tensioners, guides, and chains as a complete timing set, changing the engine oil and filter, and addressing any root cause of low oil pressure such as sludge, a restricted pickup, or a worn oil pump. If the chain has jumped timing, perform a compression or leak-down test to check for bent valves before reassembly because these Lambda engines are interference designs. Typical repair cost is about $1,500-$3,000 depending on parts replaced and labor time, with substantially higher cost if cylinder head or valve damage is found.

Frequently asked questions
What does P0019 mean on a Hyundai?
P0019 stands for "Crankshaft/Camshaft Position Correlation - Bank 2 Sensor B." This code means the engine computer detected that the crankshaft and camshaft positions on bank 2 (sensor B, typically the exhaust camshaft) are out of their expected correlation — in other words, the cam and crank timing don't line up correctly. The computer compares the crankshaft and camshaft position sensor signals to verify valve timing, which is often controlled by a variable valve timing (VVT) actuator. A correlation error points to mistimed valve events, frequently from oil-flow or VVT issues, a stretched timing chain, or sensor faults. You may notice rough idle, reduced power, poor fuel economy, or a check-engine light, and ignoring it can risk engine damage. On Hyundai it is documented across 1 model: Azera.
What are the most common causes of P0019?
The most common causes of P0019 are: Stretched or worn timing chain (and worn guides/tensioner), Faulty variable valve timing (VVT) actuator/solenoid (Bank 2), Low oil level or dirty/sludged oil restricting VVT flow, Faulty camshaft or crankshaft position sensor, Clogged VVT oil control valve screen, Damaged sensor wiring or connector, Jumped/misaligned timing during prior service. The specific cause varies by vehicle.
How much does it cost to fix P0019 on a Hyundai?
Published repair estimates on Hyundai range from $800 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.
