Removal and installation ABS wheel sensors (Mazda CX-5KE)

Front ABS wheel sensors

1. Remove the mudguard.

2. Disconnect the ABS wheel sensor connector.

3. Loosen the mounting bolt and remove the ABS wheel sensor.

4. Installation is carried out in the reverse order of removal.

5. After installation, make sure that the ABS wheel sensor is not twisted.

Rear ABS wheel sensors

1. Remove the trunk panel.

2. Remove the trunk trim edge.

3. Remove the rear door sill.

4. Remove the side trim of the trunk.



5. Disconnect the rear ABS wheel sensor connector.

6. Compress the rear ABS wheel sensor tabs and remove the sensor from the outside of the vehicle.



7. Pull back the mudguard and remove the rear ABS wheel sensor by unscrewing the mounting bolt.

8. Installation is carried out in the reverse order of removal.

9. After installation, make sure that the ABS wheel sensor is not twisted.

Checking the output parameters of the ABS wheel sensor

Caution: Checking the resistance with any testers or ohmmeters may damage the ABS wheel sensor. Use only the M-MDS diagnostic tool to check the ABS wheel sensor output.

1. Turn off the ignition.

2. Connect the M-MDS device to the DLC-2 diagnostic connector.

3. Select the following parameters:

• WSPD_SEN_LF (left Front Wheel Sensor)
• WSPD_SEN_RF (right front wheel sensor)
• WSPD_SEN_LR (left rear ABS wheel-speed sensor)
• WSPD_SEN_RR (right rear ABS wheel-speed sensor)

4. Start the engine and drive the car.

5. Check that the M-MDS display shows the same speed as the speedometer. If any deviation is found, replace the corresponding ABS wheel sensor with a new one.

Visual inspection of the installed ABS wheel sensor

Check the ABS wheel sensors for the following:

• Excessive play in ABS wheel sensor
• ABS wheel sensor deformation
• Deformation or damage to the ABS wheel sensor rotor

If any defects are found, replace the damaged component with a new one.

Checking the gap in the ABS wheel sensor

Front ABS wheel sensors

1. Remove the ABS wheel sensor from the vehicle.

2. Remove the wheel hub with the steering knuckle assembly.

3. Install the ABS wheel sensor on the removed wheel hub with the steering knuckle and tighten to a torque of 8-10 Nm.



4. Using a set of flat feeler gauges, measure the gap between the rotor and the ABS sensor.



5. If the measured value is not within the norm (0.87-1.53 mm), check the following parameters and, if necessary, replace the sensor with a new one:

• Deformation or damage to the ABS sensor rotor.
• Deformation or damage to the ABS sensor.
• Presence of foreign material on the sensor or rotor.

6. Remove the ABS wheel sensor from the wheel hub.

7. Install the wheel hub with the steering knuckle assembly.

8. Install the ABS wheel sensor.

9. Check the alignment angles of the front wheels of the vehicle.

Rear wheel sensors (versions with front-wheel drive 2WD)

1. Remove the rear ABS wheel sensor.

2. Measure the distance between the wheel sensor mounting surface and the rotor. This is dimension A.



3. Calculate the gap between the ABS wheel sensor and the rotor using the following formula:

• Gap (mm) = A - 14

4. Make sure that the obtained gap value corresponds to the norm (0.28-1.17 mm). If this is not the case, replace the sensor with a new one.

Rear wheel sensors (4WD versions)

1. Remove the ABS wheel sensor.

2. Measure the distance between the wheel sensor mounting surface and the rotor. This is dimension A.



3. Calculate the gap between the ABS wheel sensor using the following formula:

• Gap (mm) = A - 34.35

4. Make sure that the obtained gap value corresponds to the norm (0.3-1.4 mm). If this is not the case, replace the sensor with a new one.
