Product Details

The NTK AB0104 is an ABS wheel speed sensor designed to report wheel rotation data to the anti-lock braking system. Accurate wheel speed signal input helps the vehicle’s braking electronics monitor rear wheel movement and respond properly during braking events. This sensor uses a grey round connector, 2 terminals, and a 35.00-inch harness for the listed rear applications.

NTK’s technical sensor lineup is supported by OE application knowledge and testing standards developed from decades of automotive sensor experience. This part cross-references Beck/Arnley 084-4145 for the same application.

What It Helps Address

• ABS warning light related to rear wheel speed signal loss
• Intermittent wheel speed sensor fault codes
• Erratic ABS operation caused by a failing rear sensor
• Loss of accurate wheel speed data to the braking system
• Brake system communication issues on select BMW rear applications

Installation Notes

Verify connector style, harness length, and rear mounting location before installation. Inspect the tone ring, wiring path, and connector terminals for corrosion, damage, or debris that could affect signal quality. Confirm the vehicle application by year, model, and rear position before replacing the sensor. For BMW rear ABS wheel speed sensor replacement, match the OE-style connector and terminal configuration to the original part.

Quality Assurance

NTK manufactures this sensor to meet or exceed OE specifications and validates sensor performance through thermal shock, vibration, and OBD verification testing. The AB0104 is part of NTK’s full-line technical sensor coverage for import and domestic vehicles.
