Product Features and Specifications

Purpose and Common Applications

The Standard Ignition ALS1804 sensor plays a vital role in the anti-lock braking system by monitoring wheel speed and sending data to the vehicle’s ABS control module. This helps prevent wheel lockup during braking and enhances vehicle control. It is commonly used to address issues such as:

• ABS warning light illumination due to faulty sensor signals
• Intermittent or inaccurate wheel speed readings
• Traction control or stability control system malfunctions
• Uneven or compromised braking performance
• Diagnostic trouble codes related to wheel speed sensor faults

Installation Notes and Tips

Installation requires removal of the wheel and brake components to access the spindle mounting location. The sensor mounts with a single bolt, so ensure the mounting hole and bolt are clean and free of debris. Since mounting hardware and wiring harness are not included, verify the condition of existing parts before installation. Proper alignment and secure attachment are essential for accurate sensor operation. Consult vehicle-specific repair manuals for torque specifications and safety precautions.
