Check TPS
1. IG "OFF" and disconnect TPS connector.
2. Measure resistance between terminals 4 and 8 of TPS connector. ( component side)
  Specification: 4 ~ 6kΩ

3. Is the measured resistance within specification?
  YES
  - Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure
  NO
  - Substitute with a known - good ECT motor & TPS and check for proper operation. If the problem is corrected, replace ECT motor & TPS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  CAUTION:
  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. ( It will takes 10sec.)
  3. Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
