Position Sensor/Switch: Service and Repair

Temperature/pressure sensor Active On-demand Coupling, replacing

Note: As the illustrations in this service information are used for different model years and/or models, some variation may occur. However, the essential information is always correct.

Removal
Preparatory work
Ignition off.
Wait 3-4 minutes after the ignition has been switched off to reduce oil leaks on removal

Removing the control module

Note: Clean the area around the control module thoroughly before beginning removal.





Position a container underneath the Active On-demand Coupling. Disconnect the connectors for the control module and the oil pump.

Remove
- the 2 screws for the control module
- the control module with the sealing plate and the cupped washer.

Removing components from the Active On-demand Coupling





Remove the throttle valve and the temperature/pressure sensor from the coupling.
A = Throttle valve.
B = Temperature/pressure sensor.
Use a large pair of pliers for removal. Grip the end of the throttle valve. Hold the pliers stable and pull the valve straight out.

Note: Make sure that no damage is caused when removing the throttle valve. The valve cannot be replaced separately. The throttle valve is removed in order to be installed in the control module. This is done to minimize the risk of damage occurring to the contacts when installing.

Remove
- the temperature/pressure sensor as above
- the O-ring from the throttle valve seat in the coupling housing.

Installation





Installing components
Install
- control module
- the sealing plate
- washer
- the throttle valve with O-rings
- the temperature/pressure sensor with O-ring
- the O-ring for the throttle valve seat
- the screws.

Components that are included in the kit and must be replaced





- the temperature/pressure sensor with O-ring
- washer
- the O-ring for the throttle valve seat.

Position the sealing plate in the control module
Press the throttle valve and temperature/pressure sensor into place on the control module contacts. Place the cupped washer with the convex side against the temperature/pressure sensor.
Lubricate the sealing rings on the valves with oil, P/N 1161641-4 (0.3 liters).

Installing the O-ring





Carefully check that the sealing surface on the control module and valve seats in the Active On-demand Coupling is clean. Ensure that there is no trace of cloth or paper.
Lubricate the new O-ring with oil, P/N 116 16414 (0.3 liters). Press the O-ring into place in its seat.

Installing the control module for the Active On-demand Coupling





Install the control module and the valves for the coupling.





Press the control module against the coupling housing while loosely installing the screws alternately. Tighten.
Connect the connectors to the control module and the oil pump. Fill the Active On-demand Coupling with oil. Check the oil level.
Erase any diagnostic trouble codes (DTCs).
