P0746 on Hyundai by model: symptoms, diagnosis and fix
Owners of 2.0-liter Velosters equipped with Hyundai's IVT (CVT) report hesitation from a stop, shuddering under light acceleration, delayed engagement, warning messages, and in some cases reduced-power or limp-home behavior. Hyundai issued service information covering DTCs related to transmission pump/pressure and ratio monitoring, indicating this is more than isolated owner perception. Complaints commonly describe the car feeling unsafe when merging or crossing traffic because throttle input does not produce immediate movement.
Common Symptoms
- hesitation from a stop
- shudder or judder during acceleration
- delayed drive engagement
- vehicle will not accelerate normally
- check engine light or transmission warning
- limp mode
How to Fix
Scan the TCM/PCM for stored transmission codes and verify fluid condition, line pressure behavior, and software level. Hyundai service procedures typically start with TCM/ECU updates and adaptation checks; persistent cases may require IVT replacement or internal transmission repair under warranty. A careful road test from cold and after full warm-up is important because many owners report intermittent symptoms.

Frequently asked questions
What does P0746 mean on a Hyundai?
P0746 stands for "Pressure Control Solenoid Performance/Stuck Off." P0746 means the transmission's pressure control solenoid 'A' is performing poorly or appears stuck in the off (low pressure) position. This solenoid regulates hydraulic line pressure that applies clutches and bands to make smooth, firm shifts; the TCM detects when commanded pressure changes aren't producing the expected response. A stuck-off condition typically means line pressure stays low. You may experience slipping, soft or delayed shifts, harsh engagement, overheating, or the transmission entering limp mode. On Hyundai it is documented across 1 model: Veloster.
What are the most common causes of P0746?
The most common causes of P0746 are: Low, dirty, or degraded transmission fluid, Faulty pressure control / EPC solenoid, Clogged valve body passages or stuck valve, Wiring or connector fault at the solenoid, Internal transmission wear (worn clutches, leaking seals), Dirty or clogged transmission filter, Faulty transmission control module (less common). The specific cause varies by vehicle.
How much does it cost to fix P0746 on a Hyundai?
Published repair estimates on Hyundai range from $300 to $5,500 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.
