Component Inspection

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 ~ 4.1 kΩ

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 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 scantool that can erase optional parts automatically detected and memorized by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others

CAUTION: Procedure of ETS Initialization

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