Replacing the wheel speed sensor wire (Skoda Fabia 6Y)

Removal the junction box cover

Disconnecting the wiring harness from the ABS control unit connector

Fastening the front wheel speed sensor wire

Attention! ABS wires are shielded and cannot be repaired

This section describes how to replace the front wheel sensor wires. Since replacing the rear wheel sensor wires requires a special tool and wire connectors, it is recommended that this work be performed at a service station.

1. Remove the upper engine cover (see subsection 2.1).

2. On 1.9L 74kW diesel models, remove the charge air duct and the hose between the engine inlet pipe and the upper air duct.

3. Pull out the lock 2 (see figure Disconnecting the connector from the ABS control unit) pads and, pulling upwards, disconnect pad 3 from control unit 1.

4. Prying with a screwdriver 2 (see figure Removing the junction box cover), remove cover 3 of the shoe.

5. Using a screwdriver 3 (see the figure Disconnecting the wiring harness from the ABS control unit connector) move the purple lock 2 in the direction indicated by the arrow to release the wires in the connector.

6. Disconnect the wiring harness.

7. Push the corresponding wires out of the connector. The contact numbers are shown in the figure Contact numbering (1–42) of the ABS control unit connector block and in the table. Circuits connected to the connector contacts.

8. Remove the corresponding wheel.

9. Disconnect connector 1 (see the figure Fastening the wire of the front wheel speed sensor) with wires from the wheel speed sensor.

10. Remove wire 3 from holders 2.

11. Install the wire in reverse order.

12. After securing the wire in the holders, turn the steering wheel all the way to the right and left to make sure that the wire is not stretched or caught on anything.

13. When connecting the wire to the control unit connector, make sure that the wire insulation is inserted all the way into the connector hole. Secure the wiring harness braid with new clamps.
