Schrader 29181 TPMS Sensor Overview

Schrader Valves 29181 is a direct tire pressure monitoring system sensor built for vehicles that use a 315 MHz signal and clamp-in mounting. It combines an aluminum valve stem with a plastic housing, battery power, and real-time pressure signal transmission for accurate TPMS communication.

Compatible With Chevrolet Trailblazer, GMC Envoy, Saab 9-7x, Isuzu Ascender, Buick Rainier, Cadillac CTS, Cadillac SRX, Chevrolet SSR, Chevrolet Trailblazer EXT, and GMC Envoy XL applications that call for a 315 MHz direct TPMS sensor. Schrader 29181 is also a direct replacement for OE-style service needs on these platforms.

Key Features

  • Direct TPMS sensor with real-time pressure signal transmission
  • 315 MHz frequency for supported GM and related applications
  • Clamp-in design with aluminum valve stem and silver valve color
  • Battery-powered sensor with pre-programmed and programmable activation
  • Plastic housing with installed nickel-plated valve core and plastic cap
  • Includes mounting hardware and uses a direct monitoring system
  • Manufacturer warranty: 1 year

Detailed Product Description

Schrader Valves 29181 is a tire pressure monitoring system sensor engineered for direct TPMS setups that require a 315 MHz transmitter. The clamp-in aluminum valve construction supports secure wheel mounting, while the battery-powered sensor sends pressure data in real time to the vehicle’s monitoring system. This part number is commonly used across Chevrolet Trailblazer, GMC Envoy, and related GM applications, including Saab 9-7x, Isuzu Ascender, Buick Rainier, Cadillac CTS, Cadillac SRX, Chevrolet SSR, Trailblazer EXT, and Envoy XL.

This part cross-references OE numbers 25774006 and 8257740060 for the same application. Schrader 29181 is a practical service replacement when the original TPMS sensor is no longer reporting correctly or when the vehicle requires a 315 MHz direct sensor with clamp-in mounting.

What This TPMS Sensor Helps Address

  • TPMS warning light caused by a failed sensor
  • Loss of tire pressure signal transmission
  • Incorrect or missing tire pressure readings in the dash display
  • Sensor replacement needs after wheel service or aging battery failure
  • Direct TPMS communication issues on 315 MHz applications

Installation Notes and Tips

Verify the vehicle uses a 315 MHz direct TPMS sensor before installation. For listed applications, the notes specify nut torque of 62 in-lbs (7 Nm) and valve core torque of 3.5 in-lbs (0.4 Nm). Confirm wheel and sensor compatibility, then follow the vehicle service procedure for TPMS relearn or activation after installation. Schrader 29181 is pre-programmed and programmable, which supports setup on the listed applications.

Quality Assurance

Schrader Valves backs this TPMS sensor with a 1-year manufacturer warranty. The part is built with an aluminum valve stem, plastic housing, and direct-monitoring sensor design for service on supported Chevrolet Trailblazer, GMC Envoy, and related vehicle applications.
