Inspection1. After disconnecting the vapor hose from the PCV valve, remove the PCV valve. 2. Reconnect the PCV valve to the vapor hose.3. Run the engine at idle, then put a finger over the open end of the PCV valve and make sure that intake manifold vacuum can be felt.
DescriptionThe evaporator temperature sensor will detect the evaporator core temperature and interrupt compressor relay power in order to prevent evaporator from freezing by excessive cooling. The evaporator temperature sensor has the Negative Temperature Coefficient (NTC).
Inspection1.Turn the ignition switch OFF.2.Disconnect the intake actuator connector.3.Verify that the intake actuator operates to the fresh position when connecting 12V to terminal 3 and grounding terminal 4.Verify that the intake actuator operates to the recirculation position when connected in reverse.
