DTC P0096: IAT Sensor 2 Circuit Range / Performance Problem

NOTE:  Before you troubleshoot, review the general troubleshooting information - Refer to: HOW TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS or How to Troubleshoot the CVT System (CVT) .

DTC Description Confirmed DTC Pending DTC Freeze Frame
P0096 IAT Sensor 2 Circuit Range/Performance Problem      

DTC (PGM-FI)

  1. Connector visual check:

    - 1. Check for poor connections or loose terminals of these connectors.

    • ECT sensor 1
    • ECT sensor 2
    • MAF sensor/IAT sensor 1
    • IAT sensor 2

    Are the connections and terminals OK?

    YES 

    Go to step 2.

    NO 

    Repair the connections or terminals.

  2. IAT sensor 2 performance check (low temperature):

    - 1. Remove IAT sensor 2 .

    - 2. Allow IAT sensor 2 to cool to the ambient temperature.

    - 3. Note the ambient temperature.

    - 4. Connect IAT sensor 2 to its 2P connector, but do not install it.

    - 5. Turn the vehicle to the ON mode.

    - 6. Quickly note the value of IAT SENSOR 2 in the DATA LIST with the HDS.

    IAT SENSOR 2    

    - 7. Compare the value of IAT SENSOR 2 to the ambient temperature.

    Does the value of IAT SENSOR 2 differ 5.4 °F (3 °C) or more from the ambient temperature?

    YES 

    Replace IAT sensor 2 .

    NO 

    Go to step 3.

  3. IAT sensor 2 performance check (high temperature):

    - 1. Turn the vehicle to the OFF (LOCK) mode.

    - 2. Disconnect the following connector.

    IAT sensor 2 2P connector

    - 3. Using a heat gun, blow hot air on IAT sensor 2 for a few seconds. Do not apply the heat longer than a few seconds or you will damage the sensor.

    - 4. Connect IAT sensor 2 to its 2P connector, but do not install it.

    - 5. Turn the vehicle to the ON mode.

    - 6. Check IAT SENSOR 2 in the DATA LIST with the HDS.

    IAT SENSOR 2    

    Does IAT SENSOR 2 change 76 °F (42 °C) or more?

    YES 

    Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at IAT sensor 2 and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

    NO 

    Replace IAT sensor 2 .
