NTC sensors are circuitelements whose resistance decreases if the heat increases. Indoor environment sensor and evap sensor are NTC elements.Such sensors do not have a standard resistance value. They only have a usage resistance range. NTC will show different resistancevalues depending on the temperature of the environment it is in.
