4.
Is the throttle valve normal?
YES
a.
Go to "Check ETC motor resistance" as follows.
NO
a.
Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.
■ Check throttle valve for stuck
IG "OFF".
Disconnect the air hose between throttle body and air mass flow sensor.
Check stuck on throttle valve.
Is the throttle valve normal?
YES
Go to "Check ETC motor resistance" as follows.
NO
Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.
■ Check ETC motor resistance
IG "OFF".
Disconnect ETC Motor & TPS connector.
Measure the resistance between ETC motor(+) and (-) terminals of ETC Motor & TPS connector (component side).
Specification : Approx. 1.275 ~ 1.725Ω @ 23℃(73.4℉)
Is the measured resistance within specification ?
YES
Go to "ETC motor actuation test" as follows.
NO
Substitute with a known - good ETC motor and check for proper operation.
If the problem is corrected, replace ETC motor and go to "Verification of Vehicle Repair" procedure.
※ 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 10 second)
3. Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
■ ETC motor actuation test
IG "OFF".
Connect ETC motor & TPS connector.
After IG "ON", execute the "ETC motor actuation test" by Scantool.
Does the "ETC motor actuation test" execute normally?
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 ETC motor and check for proper operation. If the problem is corrected, replace ETC motor and go to "Verification of Vehicle Repair" procedure.
