Standard Ignition BST128 Brake Fluid Pressure Sensor

Brake Fluid Pressure Sensor for Nissan and Toyota

Standard Ignition BST128 is a brake fluid pressure sensor built for direct replacement in select Nissan and Toyota applications. It uses a male 3-pin terminal layout with a rectangular plug-in connector for a clean electrical connection in the brake system.

Key Features

• Brake fluid pressure sensor for brake system monitoring
• Black and gray housing
• Male connector with rectangular plug-in design
• 3-pin male terminal configuration
• No hardware, O-rings, mounting brackets, or wiring harness included
• Direct-fit replacement reference for Standard Ignition BST128

Detailed Description

Standard Ignition BST128 is a brake fluid pressure sensor used in brake pressure monitoring circuits on select Nissan Frontier, Armada, TITAN, Xterra, Pathfinder, and Pathfinder Armada models, as well as Toyota Sequoia applications. It is also a fitment match for 2002-2007 Toyota Sequoia and 2004 Nissan Pathfinder Armada, along with 2005-2021 Nissan Frontier and other listed Nissan platforms. This part cross-references 472403X00A for the same application.

With a male connector, rectangular plug shape, and 3-pin terminal design, BST128 is intended to match the original sensor connection style on the vehicle. The compact black and gray sensor body is suited for brake system service where accurate pressure signal input is required.

What It Helps Solve

• Brake warning light concerns related to pressure sensor signal faults
• Erratic or missing brake fluid pressure readings
• Electrical connector mismatch during brake sensor replacement
• Failed sensor diagnosis in Nissan Frontier, Armada, TITAN, Xterra, and Pathfinder applications
• Service replacement for Toyota Sequoia brake pressure sensor applications

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. Because hardware, O-rings, mounting brackets, and wiring harness are not included, reuse or source any required vehicle-specific components separately. Confirm the brake system is properly inspected and the electrical connector is fully seated after installation.

Quality Assurance

Standard Ignition replacement parts are built for service use in automotive electrical and brake system applications. BST128 is identified by part number BST128 and is supported by listed interchange references for application matching.
