Component Inspection

Check variable intake motor.
1. Ignition "OFF".
2. Disconnect variable intake motor connector.
3. Measure resistance between terminal "1" and "2" of variable intake motor connector.
  1. Specification: Approx. 40~70Ω (20°C/68°F)

4. Is the measured resistance within specifications?
  YES
  - Substitute with a known-good VIS motor rotation sensor and check for proper operation. If the problem is corrected, replace VIS motor rotation sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  - Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NO
  - Check variable intake motor for contamination, deterioration, or damage. Substitute with a known-good variable intake motor and check for proper operation. If the problem is corrected, replace variable intake motor and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
