Evaporator Temperature Sensor / Switch: Testing and Inspection

A/C Evaporator Temperature Sensor Inspection




Check resistance between A/C evaporator temperature sensor terminals. If check result is not in specification, replace A/C evaporator temperature sensor with the new one.

A/C evaporator temperature sensor resistance
6.1 - 7.7 kOhm at 0 °C (32 °F)
2.1 - 2.3 kOhm at 25 °C (77 °F)
