P0341 on a Hyundai: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually keep driving a Hyundai with P0341, but rough idle or hard starting is possible, so get it checked soon.

What P0341 means on a Hyundai

On a Hyundai, P0341 means the engine control unit sees a camshaft position signal from bank 1 that is outside the expected range. The sensor works with the continuously variable valve timing system to keep fuel and ignition timing correct. When the reading drifts, you may notice rough idle, hesitation, or hard starting.

Is P0341 common on Hyundais?

P0341 shows up on Hyundai models with the 2.0L and 2.4L Theta engines as the camshaft position sensors age. Oil contamination in the connector and worn variable valve timing components are also common on higher-mileage cars. The engine usually keeps running, but it may not run smoothly.

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