P0018 on Hyundai
Crankshaft/Camshaft Position Correlation - Bank 2 Sensor A
P0018 on Hyundai vehicles indicates crankshaft/camshaft position correlation - bank 2 sensor a. Au7o has documented this code across 1 Hyundai model — most commonly on Genesis Coupe. This code means the computer detected that the crankshaft and the Bank 2 'A' (typically intake) camshaft are out of their expected timing relationship. The computer compares the crankshaft and camshaft position sensor signals; they should stay in a fixed correlation as the engine turns. When the Bank 2 camshaft is too far off from the crankshaft, P0018 sets, indicating the valve timing on that bank is misaligned. This can cause rough running, reduced power, hard starting, or a no-start, and in some cases signals timing chain or phaser trouble that warrants prompt attention. Typical repair costs on Hyundai range from $1,500 to $3,600, depending on the specific model and root cause.
Common Causes of P0018
- •Stretched, worn, or jumped timing chain (Bank 2)
- •Worn or broken timing chain guides/tensioner
- •Stuck variable valve timing solenoid or phaser
- •Low or dirty engine oil affecting the phaser
- •Faulty crankshaft or camshaft position sensor
- •Damaged reluctor/tone ring
- •Incorrect timing from prior service
- •Wiring or connector fault at a cam/crank sensor

Hyundai Genesis Coupe(1 issue)
- Timing Chain Tensioner and CVVT Cam Phaser Rattle - 3.8 Lambda V62010-2016
The most consistently reported mechanical failure on the 3.8 Lambda V6 is a rattle on cold start from the timing chain system. Forum diagnosis converges on two causes: timing chain tensioners that bleed down oil pressure after the car sits, letting the chains slap until pressure builds, and worn CVVT (cam phaser) actuators whose internal lock pin no longer stays engaged. Hyundai's internal guidance treated a rattle under about three seconds as normal operation, which is why many owners were turned away at the dealer until the noise lengthened. Left alone, chain guides wear through and the chain can jump timing. This is a V6-specific failure - the 2.0T uses a different valvetrain - and it affects both the 2010-2012 MPI 3.8 and the 2013+ GDI 3.8.
