Component Inspection

Check TPS resistance
1. IG "OFF" and disconnect ETC Motor & TPS connector.
2. Measure resistance between TPS1 power and TPS1 ground terminals of ETC Motor & TPS connector.(component side)
A. Specification : 4 - 6kOhms




3. Is the measured resistance within specification?
YES
1) 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
1) 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 take 10sec.)
3. Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
