Standard Ignition ALS3556 ABS Wheel Speed Sensor - Front

Overview

Standard Ignition ALS3556 is an ABS wheel speed sensor for front applications on select Tesla models. It is built with a direct snap-fit attachment, a single bolt mount, and an included wiring harness for a clean replacement of the original sensor assembly.

Compatible with Tesla 3 and Tesla Y front applications, this sensor uses a 2-terminal, female connector with a rectangular shape and mini-blade terminals. The 27.5-inch harness length supports routing to the factory connection point, while the spindle mounting location matches the original layout.

Key Features

• ABS wheel speed sensor for brake system speed signal input
• Direct, snap-fit attachment with bolt-mount installation
• Includes wiring harness for replacement of the sensor lead
• Female connector with 2 terminals and rectangular housing
• Black and gray finish with spindle mounting location
• Fits 2017-2024 Tesla 3, front
• Fits 2020-2024 Tesla Y, front

Detailed Description

ALS3556 is a Standard Ignition ABS wheel speed sensor engineered for front fitment on Tesla 3 and Tesla Y applications. It uses a direct, snap-fit design with one bolt hole at the spindle mounting location, helping match the factory sensor interface during service. The included harness, 27.5-inch lead length, and mini-blade terminal layout support a straightforward electrical connection to the vehicle harness.

This part cross-references Monroe Shocks & Struts (e.g., 533944, 104476100E) for the same application. For buyers searching for a Tesla 3 front ABS wheel speed sensor or a Tesla Y front wheel speed sensor, ALS3556 provides the specified connector style, mounting method, and harness configuration in one replacement part.

What It Is Used For

• Restoring wheel speed signal input to the ABS system
• Replacing a damaged sensor connector or harness lead
• Addressing ABS warning lights caused by sensor circuit faults
• Correcting intermittent wheel speed data from a worn sensor
• Replacing a sensor that no longer mounts securely at the spindle

Installation Notes and Tips

Verify the connector shape, terminal count, mounting type, and harness length before installation. This sensor mounts at the spindle with a bolt mount and direct snap-fit attachment, so the factory routing path should be checked for clearance and secure seating. Confirm front application fitment for the specific Tesla 3 or Tesla Y model year before service.

Quality Assurance

Standard Ignition replacement sensors are built to match the specified connector, mounting, and harness requirements for the application. ALS3556 is identified by part number ALS3556 for accurate ordering and service verification.
