| 1. Drive belt tensioner |
Removal and Installation 1. Remove the drive belt. (Refer to Timing System - "Drive Belt") 2. Remove the drive belt idler (A). Tightening torque : 53.
Removal and Installation 1. Remove the drive belt idler. (Refer to Timing System - "Idler") 2. Remove the drive belt auto tensioner (A). Tightening torque Bolt (B) : 81.
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.
