Standard Ignition ALS1372 ABS Wheel Speed Sensor - Front Left or Front Right

ABS Wheel Speed Sensor for Differential Mounting

Standard Ignition ALS1372 is an ABS wheel speed sensor built for differential mounting and direct signal monitoring in the brake system. It uses a female connector with an oval shape, 2 terminals, and blade-style terminal design for a straightforward electrical connection.

Compatible With select Chevrolet Silverado and GMC Sierra applications, this ABS wheel speed sensor supports accurate wheel speed input for the anti-lock brake system. The ALS1372 part number is also a useful reference when matching replacement sensors by connector style and mounting location.

Key Features

• ABS wheel speed sensor for brake system signal input
• Differential mounting location
• Female connector with oval connector shape
• 2 terminals with male blade terminals
• 1 connector and 1 bolt hole mounting design
• Standard Ignition ALS1372 replacement part

Detailed Description

Standard Ignition ALS1372 is an ABS wheel speed sensor designed to read wheel speed data from the differential area and send that information to the anti-lock brake control system. The connector layout includes one female oval connector with two terminals and blade-style terminal ends, which helps match the original electrical interface on the vehicle. When replacing a failed sensor on Chevrolet Silverado or GMC Sierra trucks, matching the mounting location and connector configuration is critical for proper installation and system communication. This part number, ALS1372, is also commonly used as a reference when cross-checking replacement options for the same application.

This part cross-references 531854 and 10456154 for the same application.

What It Helps Fix

• ABS warning light caused by a failed wheel speed sensor
• Erratic or missing wheel speed signal from the differential
• Anti-lock brake system fault codes related to rear speed input
• Traction control or stability system alerts tied to wheel speed data
• Brake system performance issues caused by inaccurate sensor readings

Installation Notes and Tips

Verify the differential mounting location, connector shape, terminal count, and terminal gender before installation. Compare the original sensor to ALS1372 to confirm the electrical connection and bolt-hole layout match the vehicle. Clean the mounting area and inspect the harness connector for corrosion or damaged terminals before reconnecting the system.

Quality Assurance

Standard Ignition replacement electrical components are built to meet application-specific fit and function requirements. Confirm vehicle coverage by matching the part number ALS1372 and the original sensor configuration before installation.
