Schrader Valves 20281 Tire Pressure Monitoring System (TPMS) Sensor

TPMS Sensor for Hyundai and Kia

Schrader Valves 20281 is a direct tire pressure monitoring system (TPMS) sensor built for Hyundai and Kia applications that use a 433 MHz signal. It uses a snap-in mounting method, a rubber valve, and a battery-powered direct monitoring design to transmit real-time tire pressure data to the vehicle system.

Compatible With Hyundai Palisade, Santa Fe, Tucson, Sonata, Veloster, and Nexo, as well as Kia Telluride, Sedona, and K900 applications that call for this sensor type. The Schrader Valves 20281 is pre-programmed and non-programmable for straightforward replacement service.

• Direct TPMS sensor with real-time pressure signal transmission
• 433 MHz frequency for supported Hyundai and Kia platforms
• Snap-in mounting with rubber valve construction
• Pre-programmed, non-programmable sensor format
• Black valve color with plastic housing
• Includes installed Ni plated valve core, plastic cap, and aluminum nut
• Cross-references Dorman - OE Solutions 974-055 and Standard Ignition TPM169 for the same application

Detailed Product Overview

This Schrader Valves TPMS sensor is engineered for direct tire pressure monitoring on a wide range of Hyundai and Kia vehicles from 2014 through 2025. It is a fitment-based replacement for models such as the Hyundai Palisade, Hyundai Santa Fe, Hyundai Tucson, Hyundai Sonata, Hyundai Veloster, Hyundai Nexo, Kia Telluride, Kia Sedona, and Kia K900. Part number 20281 is specified for 433 MHz systems and is built to deliver live pressure data to the vehicle’s TPMS receiver.

Because it is pre-programmed and non-programmable, this sensor is suited to applications that call for a ready-to-install OE-style replacement rather than a configurable universal unit. The snap-in design, rubber valve, and included mounting hardware support standard TPMS service procedures on the listed Hyundai and Kia platforms.

Common TPMS Issues It Can Address

• TPMS warning light caused by a failed sensor battery
• Loss of tire pressure data on 433 MHz Hyundai or Kia systems
• Intermittent or inaccurate pressure readings from an aging sensor
• Sensor replacement after tire service or wheel service
• Restoring direct monitoring on vehicles with a damaged valve-mounted sensor

Installation Notes and Tips

Verify the vehicle uses a 433 MHz direct TPMS system before installation. For listed Hyundai and Kia applications, follow the specified torque values where provided: screw torque 11.5 in-lbs (1.3 Nm) and valve core torque 3.5 in-lbs (0.4 Nm). Always confirm fitment by year, make, model, and TPMS frequency before service.

Quality Assurance

Schrader Valves backs this sensor with a 1-year manufacturer warranty. Part number 20281 is built as a direct replacement for supported Hyundai and Kia TPMS applications and is listed with OE-style interchange references for service matching.
