Components 1. Piston ring2. Piston3. Connecting rod4. Connecting rod upper bearing5. Piston pin6. Connecting rod lower bearing7. Connecting rod bearing cap8.
Removal 1. Remove the LH/RH cylinder head assembly and gasket. (Refer to Cylinder Head Assembly - "Cylinder Head") 2. Remove the water jacket seperators (A).
Inspection 1. Ignition "ON" 2. Using the scan tool. 3. Emit intensive light toward photo sensor using a lamp, and check the output voltage change. 4. The voltage will rise with higher intensive light and reduce with lower intensive light.
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.
