DTC Troubleshooting: P0096(2.0L Engine): Inspection

Connector Visual Inspection 

Test Procedure 

• Procedure
• • Check the connectors for a secure connection or for loose terminals at the following components:

    ECT sensor 1

    ECT sensor 2

    MAF sensor/IAT sensor 1

    IAT sensor 2

• Normal Conditions
• • Conditions at the connections and terminals are OK.

Results 

• If it is abnormal, there is a problem with the connections or terminals.

IAT Sensor 2 Inspection (Low Temperature) 

Test Procedure 

• Preparation
• • IAT sensor 2: removed and cooled to the ambient temperature

• Procedure
• • Note the ambient temperature.
  • Connect the IAT sensor 2 2P connector, but do not install IAT sensor 2.
  • Turn the vehicle to the ON mode.
  • Quickly note the HDS [IAT Sensor (2)] value.
  • Compare the HDS [IAT Sensor (2)] value to the ambient temperature.

• Normal Conditions
• • The difference between the HDS [IAT Sensor (2)] value and the ambient temperature is less than 5.4 deg.F (3 deg.C)  .

Results 

• If it is abnormal, there is a problem with IAT sensor 2.

IAT Sensor 2 Inspection (High Temperature) 

Test Procedure 

• Preparation
• • IAT sensor 2: removed

• Procedure
• • Connect the IAT sensor 2 2P connector, but do not install IAT sensor 2.
  • Turn the vehicle to the ON mode.
  • Heat IAT sensor 2 with heat gun for a few seconds.
    NOTE: Do not apply the heat longer than a few seconds or you will damage the sensor.
  • Confirm the HDS [IAT Sensor (2)].

• Normal Conditions
• • HDS [IAT Sensor (2)] value is more than 76 deg. F (42 deg. C)  .

Results 

• If it is abnormal, there is a problem with IAT sensor 2.
