Pressure Sensor

Description and Operation

Description

The AWD ECM rotates the pump motor (actuator) to generate oil pressure. It then presses the multi-plate clutch and transmits the generated torque to the rear wheels. The torque value varies depending on the pressure condition.

Repair Procedures

Inspection

Measure the pressure sensor resistance.

1. 1
   Turn the ignition off.
2. 2
   Disconnect the pressure sensor connector.
3. 3
   Measure the resistance between the sensor terminal and the terminal.
4. 4
   Check the measured resistance. (Refer to the table)

[Table 1]

Terminal	Resistance
PIN 2 – PIN 3	153.2 - 255.36 kΩ
PIN 1 – PIN 3	50.3 - 75.6 kΩ
PIN 1 – PIN 2	123.36 - 328.56 kΩ

Removal

1. 1
   Remove the coupling assembly. (Refer to All-Wheel Drive (AWD) System - Coupling Assembly)

   Keep it level with the label (A) on the upper part of the connector.

2. 2
   Remove the pressure sensor (A).

   Keep the coupling horizontal to prevent leaks while removing the pressure sensor.

   Tightening torque: 10.8 - 14.7 N·m

   

   

Installation

1. To install, reverse the removal procedure.

Before installation, check that the pressure sensor is clean. Inspect the O-ring of the pressure sensor (A). Keep it level with the label (A) on the upper part of the coupling.
