Component Inspection

  1. Check ETS motor
    1. Ignition "OFF"
    2. Disconnect ETS motor connector
    3. Measure resistance between terminals "1" and "2" of the ETS motor connector.

      Specification: Approx. 1.275 ~ 1.725Ω at 20°C (68 °F)

    4. 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.
  2. Check TPS
    1. 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)

    2. 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)
    3. 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

    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 1 second to record the throttle motor position on the EEPROM
