Test Point 3 - Engine Temperature Sensor II

TEST POINT 3 - Engine temperature sensor II - Fault code 2_14

Possible Causes, Elimination, Remarks
- Disconnect the EZK control unit plug.
- At the EZK control unit plug, connect terminals 19 and 18 with the ohmmeter.

Display at:
0°C (32° F) = 4.4 - 6.8k Ohms
15-30°C (59-86° F) = 1.4 - 3.6k Ohms
40°C (104° F) = 1.0 - 1.3k Ohms
80°C (176° F) = 250 - 390 Ohms
100°C (212° F) = 160 - 210 Ohms

If these values are not reached, test at the sensor in the thermostat housing. However, do not connect both contact tabs with the ohmmeter but test each plug contact at the temperature sensor separately against ground (there are two independent temperature sensors).
