Component Inspection
- Check ETS motor
- Ignition "OFF"
- Disconnect ETS motor connector
- Measure resistance between terminals "1" and "2" of the ETS motor connector.
Specification: Approx. 1.275 ~ 1.725Ω at 20°C (68 °F)
- Is the measured resistance within specifications?
YES
- Go to 2 "Check TPS" as below
NO
- Substitute with a known-good ETS motor and check for proper operation. If the problem is corrected, replace ETS motor and then do "ETS Initialization" and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- Check TPS
- Disconnect TPS connector and measure resistance between terminals 4 and 8 of the TPS connector.
Specification: Approx. 4.0~6.0kΩ ( with throttle valve fully closed) at 20°C (68°F)
- Disconnect TPS connector and measure resistance between terminals 1 and 5 of the TPS connector.RESISTANCE SPECIFICATION
Item Sensor Resistance TPS 1 4.0 ~ 6.0 kΩ (20°C) TPS 2 2.72 ~ 4.08 kΩ (20 °C) - Are the TPS resistance within specifications?
YES
- Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure. If PCM needs to be replaced, do "ETS Initialization" after it is replaced.
NO
- Substitute with a known-good TPS and check for proper operation. If the problem is corrected, replace TPS and then do "ETS Initialization". And go to "VERIFICATION OF VEHICLE REPAIR " procedure.
* 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 10 second)
- Turn ignition key on more than 1 second to record the throttle motor position on the EEPROM
- Disconnect TPS connector and measure resistance between terminals 4 and 8 of the TPS connector.
