Evaporator temperature sensor

Connect the leads of an ohmmeter to evaporator temperature sensor terminals 3 and 4

Feed the drain tube through the hole in the bulkhead

Ambient temperature sensor

Ambient temperature sensor (arrowed)

7 To test the sensor, connect the leads from an ohmmeter to the sensor terminals, and measure the resistance. At 25°C the resistance should be 1.7 ± 0.85 Ohms, and at 50°C the resistance should be 0.6 ±0.1 Ohms.

8 Refitting is a reversal of removal.

9 Remove the radiator grille as described in Chapter 11.

10 Disconnect the wiring plug, release the connector clamp, then carefully prise the sensor from position (see illustration).

11 To test the sensor, connect the leads from an ohmmeter to the sensor terminals, and measure the resistance. At 25°C the

resistance should be 1.6 to 1.8 kOhms, and at 40°C the resistance should be 0.5 to 0.7 kOhms. 12 Refitting is a reversal of removal.

13 To test the sensor in place, remove the glovebox (Chapter 11, Section 27), connect the leads from an ohmmeter to the sensor terminals 3 and 4, and measure the resistance. At 25°C the resistance should be 1.5 kOhms.

(see illustration).

14 To renew the sensor, remove the evaporator as described in Section 16.

15 Carefully pull the sensor from position

(see illustration 16.8a).

16 Refitting is a reversal of removal.
