Ignition " ON".
A/C switch ON.
Disconnect evaporator temprature sensor connector.
Using the multi-tester, Measure resistance between terminal "1" and "2" of evaporator temperature sensor.
Evaporator core temperature [℃(℉)] | Resistance [㏀] |
-10(14) | 18.31 |
0(32) | 11.60 |
10(50) | 7.55 |
15(59) | 5.04 |
30(86) | 3.44 |
40(104) | 2.40 |
If the measured resistance is not specification, substitute with a known-good evaporator temperature sensor and check for proper operation.
If the problem is corrected, replace the evaporator temperature sensor.
