Hyundai Tucson: Coupling Assembly / Pressure Sensor

- Description The 4WD ECU makes a Motor Pump(Actuator) turn round for generating an oil pressure. And then it presses a multiple disk clutch and transfers the generated torque into rear wheels. Its torque value varies according to a pressure status.

• Component location

Measure the resistance of pressure sensor

1.Turn ignition switch OFF.

2.Disconnect the pressure sensor connector.

3.Measure resistance between sensor terminal and terminal.

4.Check the measured resistance. (Refer to table)

• Be careful not to damage the parts located under the vehicle (floor under cover, fuel filter, fuel tank and canister) when raising the vehicle using the lift.(Refer to General Information - "Lift and Support Points")

1.Remove the coupling assembly.(Refer to 4 Wheel Drive (4WD) System - "Direct Electro Hydraulic Actuator Coupling")

• Keep it level with the sticker (A) on the top of the coupling.

2.Remove the pressure sensor (A).

• Keep going horizontal state to prevent leaks during remove the pressure sensor.

Tightening torque:10.8 - 14.7 N.m (1.1 - 1.5 kgf.m, 8.0 - 10.8 lb-ft)

1.To install, reverse the removal procedure.

• Check the cleanliness of the pressure sensor before installation.

• Check the pressure sensor O-ring (A).

• Keep it level with the sticker (A) on the top of the coupling.
