C-Tzu Front ABS Wheel Speed Sensor for GM Trucks & SUVs, Left/Right ALS482 Direct-Fit OE Signal

This C-Tzu front ABS wheel speed sensor is a direct-fit replacement designed for a wide range of GM vehicles, including Silverado, Avalanche, Suburban, Tahoe, Sierra, Yukon XL, Savana, Escalade and select Hummer H2 models. Built to match OE fit and signal characteristics, it aims to restore reliable anti-lock braking system (ABS) feedback without modifications. The sensor is offered as a left and right option and cross-references common part numbers ALS482, 15991986, 15037208, ABS3513FLR and 9181873 to help you confirm compatibility.

Which vehicles will this C-Tzu speed sensor fit?

This sensor covers many GM platforms from the late 1990s through early 2010s. Confirm fitment by checking the year, model and OEM cross-reference numbers before purchase.

• 2002–2006 Avalanche 1500/2500
• 1999–2006 Chevrolet Silverado series
• 2003–2013 Chevrolet Savana
• 2002–2006 Cadillac Escalade
• 2003–2007 Hummer H2 and various GMC/Chevy SUVs and vans

How does this part restore ABS function and dashboard warnings?

The C-Tzu ALS482 senses wheel rotation and sends a real-time electrical signal to the ABS control module. Replacing a failing sensor corrects inaccurate or missing wheel-speed input, which often extinguishes ABS warning lights once the module detects valid signals.

• Accurate wheel-speed detection reduces false ABS faults
• Signals match OE response to ensure proper ABS timing
• Compatible connector and harness reduce wiring errors

Is installation difficult and what tools are needed?

Installation is designed to be straightforward for a mechanic or a confident DIYer. The sensor attaches with OE-style mounting and plugs directly into the factory wiring harness, removing the need for cutting or splicing.

• Plug-and-play electrical connector—no soldering required
• Common hand tools (socket, ratchet, torque wrench and jack stands)
• Typical install time: 30–90 minutes per side depending on access

What technical benefits does this replacement sensor provide?

Beyond restoring ABS operation, the sensor helps the vehicle maintain consistent braking support and handling feedback. It’s manufactured to give stable signal transmission and durable performance against road exposure.

• Precise signal transmission for timely ABS responses
• Robust housing resists water, dirt and road debris
• Replaces common OEM numbers for straightforward sourcing

Who is this for: This C-Tzu front ABS wheel speed sensor is intended for owners and technicians servicing compatible Chevrolet, GMC, Cadillac or Hummer vehicles that show ABS warning lights, inconsistent braking feel, or that need a reliable OEM-style replacement. It’s suitable for DIY installers who can perform basic wheel removal and electrical checks, as well as professional shops seeking a cost-effective direct replacement that fits common GM models.
