Component Inspection

Component Inspection

1. Check TPS
(1) IG "OFF" and disconnect TPS connector.
(2) Measure resistance between terminals 6 and 7 of TPS connector. (Component side)
A. Specification : 2.7 - 4.1kOhms




(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.

CAUTION:
There is a memory reset function on scantool that can erase optional components automatically detected and memorized by PCM.Before or after testing PCM on the vehicle, use this function to reuse the PCM.

CAUTION:
Procedure of ETS Initialization
1. Erase the trouble codes on PCM
2. Turn the ignition key off and maintain this condition until the main relay is turned off. (It will take 10 sec).
3. Turn ignition key on more than 1 second to record the throttle motor position on the EEPROM
