Detailed Description

Holstein 2ABS3154 is an ABS wheel speed sensor application matched to specific Subaru Legacy and Subaru Outback front positions. The fitment data includes 2015-2019 model coverage, with separate listings for front, front left, and front right configurations depending on the vehicle and build date. For 2018 and 2017 vehicles, the notes indicate harness-equipped applications with production-date limits, so matching the exact year, position, and note is important before ordering. The part number 2ABS3154 is also cross-referenced to OE-style numbers 27540-AL00A and 27540AL00A for the same application.

What It Helps Address

• ABS warning light caused by a failed wheel speed sensor
• Intermittent wheel speed signal loss
• Brake control system faults related to sensor input
• Incorrect sensor fitment when the harness or position differs

Installation Notes

Verify the exact Subaru Legacy or Subaru Outback fitment by year, position, and production-date note before installation. Match harness-equipped listings only to vehicles that call for that configuration. Confirm connector style and mounting location against the removed sensor and vehicle build information. The part number 2ABS3154 should be checked against the vehicle application before final installation.
