About ABS Pump Part Number 58920 3W800

The ABS pump with part number 58920-3W800 is a hydraulic control unit used primarily in certain Toyota and Lexus vehicles manufactured between the late 2000s and early 2010s. It functions as the core component of the Anti-lock Braking System (ABS), regulating brake fluid pressure during rapid stops to prevent wheel lockup. This particular model integrates with electronic stability control (ESC) and traction control systems, making it essential for safe handling on slippery surfaces.

Commonly found in models such as the Toyota Sienna (2004–2010), Camry (2007–2011), RAV4 (2006–2012), and Lexus RX350 (2007–2012), this pump ensures precise modulation of brake force across all wheels. The unit typically includes solenoid valves, a pump motor, accumulator, and integrated electronic control module. Because it operates under high pressure and must respond within milliseconds, its mechanical and electrical integrity is crucial.

It’s important to note that while some variations may appear visually similar, differences in firmware, sensor layout, or connector pin configuration can render a seemingly identical unit incompatible. Therefore, buyers should not rely solely on part number matching without confirming fitment through manufacturer documentation or professional verification.
