Throttle Position Sensor Resistance Inspection

  1. Ignition "OFF".
  2. Disconnect Battery (-) terminal.
  3. Refer to "ETC REMOVAL " and disconnect Throttle Body connector.
  4. Measure resistance between Pin No. 4 (TPS1 Signal) terminal and Pin No. 2 (TPS Supply) terminal of Throttle Body harness connector.
  5. Measure resistance between Pin No. 5 (TPS2 Signal) terminal and Pin No. 2 (TPS Supply) terminal of Throttle Body harness connector.

    Specification: 

    TPS1: 0.875 ~ 1.625 kΩ (68°F/20°C)

    TPS2: 0.875 ~ 1.625 kΩ (68°F/20°C)

  6. Is the measured value within specification?

    YES 

    • Carefully re-do this troubleshooting guide steps.
    • If the diagnostics have been performed correctly with no failure found, replace the ECM/PCM and then go to "Verification Of Repair " procedure.
    CAUTION: When replacing the ECM/PCM, the vehicle equipped with the immobilizer must be performed procedure as below.
    [In the case of installing used ECM/PCM]
    1. Perform "ECM/PCM Neutral mode" procedure with KDS. (Refer to "IMMOBILIZER " )
    2. After finishing "ECM/PCM Neutral mode", perform "Key Teaching" procedure with KDS. (Refer to "IMMOBILIZER " )

    [In the case of installing new ECM/PCM]
    Perform "Key Teaching" procedure with KDS. (Refer to "IMMOBILIZER " )
    CAUTION: When replacing the ECM/PCM, the vehicle equipped with the smart key system (Button start) must be performed procedure as below.
    [In the case of installing used ECM/PCM]
    1. Perform "ECM/PCM Neutral mode" procedure with KDS. (Refer to "SMART KEY " )
    2. After finishing "ECM/PCM Neutral mode", insert the key (or press the start button) and turn it to the IGN ON and OFF position. Then the PCM learns the smart key information automatically.

    [In the case of installing new ECM/PCM]
    Insert the key (or press the start button) and turn it to the IGN ON and OFF position. Then the ECM/PCM learns the smart key information automatically.

    NO 

    • Carefully re-do this troubleshooting guide steps.
    • If no problems were found with the circuits or connectors, replace Throttle Body and then go to "Verification Of Repair " procedure.
    CAUTION:
    • Install the component with the specified torques.
    • Note that internal damage may occur when the component is dropped or mis- treated.
