Removing, checking and installing the engine coolant temperature sensor Mitsubishi Outlander 

1. Make sure the ignition switch is in the "OFF" position.

2. Before removing the coolant temperature sensor, drain the antifreeze from the engine as described  here .

3. Disconnect the wire from the negative terminal of the storage battery.

4. Then disconnect the wiring block from the coolant temperature sensor connector (the location of the wiring block is shown on the removed engine for clarity, the first photo is the 4B12 engine, the second is 6B31).

5. Remove the coolant temperature sensor using a special tool (tool head, catalog number MB992042).

6. Checking the coolant temperature sensor is carried out in this way. Connect a multimeter in ohmmeter mode to the sensor leads. To measure the resistance at the terminals of the coolant temperature sensor at different temperature conditions, lower the sensor's sensitive element into hot water and check the change in its resistance as the water cools down, monitoring the water temperature with a thermometer. Resistance ratings at different temperatures are shown in the table below.

Note:

There should be enough water in the vessel to cover the entire fuser tip, but not above the threads.

7. If the measured resistance differs significantly from the nominal value, replace the coolant temperature sensor.

8. Clean the sensor threads if installing an old sensor.

9. Apply the specified sealant to the threads of the transducer as shown.

Note:

Sealant - Three bond 1324N or equivalent.
Install the sensor as soon as possible after applying the sealant (within 3 to 5 minutes).
After installing the sensor, wait at least an hour before refilling with coolant.

10. Install and tighten the Mitsubishi Outlander HL temperature sensor to the specified nominal torque.

Note:

The tightening torque is 30 ± 9 Nm.
Similar to the removal procedure, tighten the coolant temperature sensor using a special tool (tool head MB992042).
