Evaporator temperature sensor
Use SDP3 to check the values from the evaporator temperature sensor, air temperature sensor and cab temperature sensor. Cab temperature can be read from the instrument cluster.If the values do not correspond, check the wiring and connectors on the temperature sensor which shows the incorrect value.If necessary, renew the temperature sensor which shows the incorrect value.Clear the fault codes in the ACC control unit.
