Check TPS
1. IG "OFF" and disconnect TPS connector.
2. Measure resistance between terminals 1 and 5 of TPS connector (Component side).
  Specification: 2.7-4.1kΩ

3. Is the measured resistance within specification?
  YES
  - Substitute with a known-good ECM and check for proper operation. If the problem is corrected, replace ECM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NO
  - Substitute with a known-good TPS and check for proper operation. If the problem is corrected, replace TPS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by ECM. After testing ECM on the vehicle, use this function before reusing the ECM
CAUTION:
Procedure of ETS Initialization
1. Erase the trouble codes on ECM
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
