P0746 on Hyundai
Pressure Control Solenoid Performance/Stuck Off
P0746 on Hyundai vehicles indicates pressure control solenoid performance/stuck off. Au7o has documented this code across 1 Hyundai model — most commonly on Veloster. 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. Typical repair costs on Hyundai range from $300 to $5,500, depending on the specific model and root cause.
Common Causes of P0746
- •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)
P0746 on Hyundai by Model
Hyundai Veloster(1 issue)
- Smartstream IVT/CVT Hesitation, Judder, and Limp-Mode from Transmission Control Logic or Internal Faults2019-2021
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.
