Wheel Speed Sensor

REMOVAL AND INSTALLATION

1993-97 626, MX6 and 1995-97 Protege

1. Raise and safely support the vehicle.
2. Remove the wheel.
3. Disconnect the connector. Remove the mounting bolts/nuts and remove the sensor.
4. Installation is the reverse of removal. Torque the bolts at the sensor to 12-16 ft. lbs. (16-22 Nm).

1995-97 Millenia

Front

1. Disconnect the negative battery cable. Wait at least 90 seconds before performing any work.
2. Working from under the hood disconnect the ABS speed sensor electrical connector.
3. Raise and safely support the vehicle and remove the tire and wheel.
4. Remove the two nuts and the ABS sensor wire bracket from the body.
5. Remove the two nuts and remove the speed sensor wire clamp from the strut bracket.
6. Remove the grommet and draw out the speed sensor wire from the engine compartment.
7. Remove the bolt attaching the speed sensor wire clamp to the knuckle.
8. Remove the mounting bolt and remove the ABS speed sensor.

   To install:

9. Install the ABS speed sensor with its mounting bolt and torque to 14-18 ft. lbs. (19-25 Nm).

   Fig. 2:Measuring speed sensor clearance -- 1995-97 Millenia and RX7

10. Check the clearance between the wheel-speed sensor and the sensor rotor. Clearance is 0.012-0.043 in. (0.3-1.1 mm). If clearance is not within specifications, replace the ABS sensor or the sensor rotor as necessary.
11. Install the speed sensor wire clamp to the steering knuckle with the bolt. Bolt torque is 14-18 ft. lbs. (19-25 Nm).
12. Feed the ABS speed sensor wire into the engine compartment. Reinstall the grommet.
13. Install the wire clamp to the strut bracket with the two nuts and install the wire clamp to body bracket with the two nuts. Torque all the nuts to 70-95.4 in. lbs. (7.9-10.7 Nm).
14. Reinstall the tire and wheel and safely lower the vehicle.
15. Reconnect the speed sensor electrical connector.
16. Reconnect the negative battery cable.

Rear

1. Disconnect the negative battery cable. Wait at least 90 seconds before performing any work.
2. Disconnect the speed sensor electrical connector.
3. Remove the bolts attaching the sensor wire clamps to the body and the strut assembly.
4. Remove the speed sensor mounting bolt and remove the sensor.
5. Installation is the reverse of removal. Mounting bolt and wire clamp mounting bolts are tightened to 14-18 ft. lbs. (19-25 Nm).
