Removal [Knock Sensor #1 (Bank 1)] 1. Turn the ignition switch OFF and disconnect the battery negative (-) cable. 2. Disconnect the knock sensor connector (A).
Inspection 1. Ignition "OFF" 2. Disconnect ambient temperature sensor. 3. Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature. 1. Sensor Ground2.
Inspection 1. Ignition "OFF". 2. Disconnect the intake actuator connector. 3. Verify that the actuator operates to the recirculation position when connecting 12V to the terminal 3 and grounding terminal 7. 4. Verify that the intake actuator operates to the fresh position when connecting in the reverse.
