Mitsubishi Outlander: Wheel Speed Sensor

REMOVAL AND INSTALLATION

CAUTION The vehicle speed detection encoder collects any metallic particle easily, because it is magnetized.

Make sure that the encoder should not collect any metallic particle. Check that there is not any trouble prior to reassembling it.

Pre-removal and post-installation operation

• Air cleaner body assembly removal and installation <Refer to GROUP 15 − Air Cleaner (3000)>.

  Front wheel speed sensor (LH)

• Quarter trim removal and installation (Refer to GROUP 52A − Trim). Rear wheel speed sensor

Front wheel speed sensor removal steps

1. Bolt (front wheel speed sensor and knuckle connection)
2. Front wheel speed sensor connector
3. Front wheel speed sensor grommet
4. Front wheel speed sensor
5. Harness clip

Rear wheel speed sensor removal steps

6. Bolt (rear wheel speed sensor and rear wheel hub assembly connection)
7. O-ring
8. Rear wheel speed sensor connector
9. Rear wheel speed sensor grommet
10. Rear wheel speed sensor
11. Protector

NOTE: The vehicle speed detection encoder is integrated with the front wheel bearing and the rear hub assembly, which cannot be disassembled.

INSTALLATION SERVICE POINTS

REAR WHEEL SPEED SENSOR, O-RING, AND BOLT (CONNECTION OF REAR WHEEL SPEED SENSOR WITH REAR WHEEL HUB ASSEMBLY) INSTALLATION <VEHICLES WITH 5 SEATING CAPACITY>

1. Align the mounting bolt hole position of rear wheel speed sensor with the mounting bolt hole position of rear wheel hub assembly.

CAUTION

• Do not insert the rear wheel speed sensor at an angle or by prying the sensor because it may be possible that the O-ring of rear wheel speed sensor cannot be mounted properly.
• After the insertion, do not perform an alignment of mounting bolt hole positions by rotating the rear wheel speed sensor.

2. As shown in the figure, mount the rear wheel speed sensor while keeping the sensor perpendicular to the rear wheel hub assembly.

HARNESS CLIP INSTALLATION

Install the front wheel speed sensor to the harness clip as shown in the figure.

FRONT WHEEL SPEED SENSOR GROMMET/REAR WHEEL SPEED SENSOR GROMMET INSTALLATION

Install the front wheel speed sensor grommet and the rear wheel speed sensor grommet to the body panel snugly as shown in the figure.

INSPECTION

WHEEL SPEED SENSOR CURRENT CHECK

CAUTION Do not connect the battery terminals in reverse as the wheel speed sensor may be damaged.

1. Connect the circuit tester to the wheel speed sensor using the special tool extra fine probe (MB992006), and measure the sensor current as a single unit.

Standard value: 5.9 to 8.4 mA or 11.8 to 16.8 mA

2. If the measurement value is not within the standard value range, replace the wheel speed sensor with a new one.

WHEEL SPEED SENSOR INSULATION CHECK

1. Connect the circuit tester to the wheel speed sensor using the special tool extra fine probe (MB992006), and measure the insulation resistance between terminal No. 1/2 and the wheel speed sensor body as a single unit.

Standard value: 5 MΩ or more

2. If the insulation resistance is not within the standard value range, replace the wheel speed sensor with a new one.
