P0841 on Hyundai
Transmission Fluid Pressure Sensor/Switch "A" Circuit Range/Performance
P0841 on Hyundai vehicles indicates transmission fluid pressure sensor/switch "a" circuit range/performance. Au7o has documented this code across 1 Hyundai model — most commonly on Veloster. This powertrain code means the transmission computer detected the 'A' transmission fluid pressure sensor or switch reading out of its expected range or not matching actual operating conditions. This sensor converts hydraulic line pressure into an electrical signal the computer uses to manage shift timing and quality. An out-of-range reading can cause incorrect shift behavior, harsh or slipping shifts, or limp mode. It should be addressed to prevent drivability problems and possible transmission damage. Typical repair costs on Hyundai range from $300 to $5,500, depending on the specific model and root cause.
Common Causes of P0841
- •Low or contaminated transmission fluid
- •Faulty transmission fluid pressure sensor/switch
- •Wiring or connector problems in the sensor circuit
- •Clogged filter or restricted fluid passages
- •Worn valve body or internal pressure control fault
- •Faulty transmission control module (less common)
P0841 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.
