Component Inspection

  1. Check resistance of ETS Motor
    1. IG "OFF"
    2. Disconnect ETS motor & TPS connector.
    3. Measure resistance between terminal 2 and 3 of ETS motor & TPS connector (Component Side).

      Specification: Prix. 1.275-1.725Ω@ 23°C(73.4°F)

    4. Is the measured resistance within specifications?

      YES 

      • 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 

      • Substitute with a known-good ETC and check for proper operation.

      If the problem is corrected, replace ETC and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

    Procedure of ETS Initialization 

    1. Erase the trouble codes on PCM
    2. Turn the ignition key off and keep this condition until the main relay is turned off.(10 sec.)
    3. Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
