DIAGNOSTIC TROUBLE CODE (DTC) – P1535 EVAPORATOR TEMPERATURE
Circuit Description
A semiconductor which resistance is noticeably
changed as the change of temperature. When the refrig-
erant temperature of the evaporator drops to 0°C (0°F)
and below, the evaporator cores get stuck with frost or
ice, reducing the airflow, lowering the cooling capacity.
The thermistor is a sensor which is used to prevent from
frosting or icing. The thermistor is installed on the evap-
orator.
Conditions for Setting the DTC
D A short to battery voltage condition exists and is pres-
ent for more the 2 seconds.
