Standard Ignition FLS-159 Brake Fluid Level Sensor

Brake Fluid Level Sensor for Nissan Applications

Standard Ignition FLS-159 is a brake fluid level sensor built for vehicles that use an electrical warning circuit to monitor reservoir fluid level. It features a female plug-in connector, two male blade terminals, and a sensor-only contents listing for direct replacement service.

Key Features

• Brake fluid level sensor for reservoir monitoring
• Female connector with plug-in design
• 2 male blade terminals for electrical connection
• Direct-fit replacement for select Nissan models
• Cross-references Standard Ignition FLS-159 and OE-style applications

Detailed Description

Standard Ignition FLS-159 is a brake fluid level sensor used to restore proper fluid-level signaling in the brake system. When the reservoir level drops, the sensor helps trigger the warning circuit so the driver can address a low-fluid condition before braking performance is affected. This part is a direct replacement for select Nissan LEAF, GT-R, Rogue, Altima, Sentra, and Juke applications, including 2012-2017 Nissan LEAF, 2009-2016 Nissan GT-R, 2010-2013 Nissan Rogue, 2008 Nissan Rogue, 2007-2012 Nissan Altima, 2008-2012 Nissan Sentra, 1995-2002 Nissan Sentra, and 2011 Nissan Juke. This part cross-references 5S14964 and 71-3725 for the same application.

What It Helps Fix

• Brake warning light stays on due to a faulty fluid level sensor
• No low-fluid warning when reservoir level drops
• Intermittent brake fluid level signal from worn electrical contacts
• Sensor connector damage at the reservoir connection point
• Incorrect brake fluid level readings during inspection or diagnosis

Installation Notes and Tips

Verify connector style, terminal layout, and reservoir fitment before installation. Inspect the brake fluid reservoir opening and electrical connector for corrosion, contamination, or damaged terminals before transferring the new sensor into service. After installation, confirm the brake warning circuit operates correctly with the ignition on and the reservoir at the proper fluid level.

Quality Assurance

Standard Ignition is a recognized aftermarket source for electrical and sensor components, and FLS-159 is built to match the specified connector and terminal configuration for the listed Nissan applications.
