DTC P0096: IAT Sensor 2 Circuit Range/Performance Problem

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.

1. Check for poor connections or loose terminals at ECT sensor 1 and IAT sensor 2.

Are the connections and terminals OK?

YES - Go to step 2.

NO - Repair the connectors or terminals, then go to step 15.

2. Remove IAT sensor 2.
3. Allow IAT sensor 2 to cool to 77 degrees F (25 degrees C).
4. Note the ambient temperature.
5. Connect IAT sensor 2 to its 2P connector, but do not install it into the intake manifold.
6. Turn the ignition switch ON (II).
7. Note the value of IAT SENSOR 2 quickly in the DATA LIST with the HDS.
8. Compare the value of IAT SENSOR 2 and the ambient temperature.

Does the value of IAT SENSOR 2 differ 5.4 degrees F (3 degrees C) or more?

YES - Go to step 13.

NO - Go to step 9.

9. Disconnect IAT sensor 2 from the 2P connector.
10. Blow hot air on IAT sensor 2 with a hair dryer.
11. Connect IAT sensor 2 to its 2P connector, but do not install it into the intake manifold.
12. Check IAT SENSOR 2 in the DATA LIST with the HDS.

Did IAT SENSOR 2 change 58 degrees F (32 degrees C) or more?

YES - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at IAT sensor 2 and the PCM.

NO - Go to step 13.

13. Turn the ignition switch OFF.
14. Replace IAT sensor 2.
15. Turn the ignition switch ON (II).
16. Reset the PCM with the HDS.
17. Do the PCM idle learn procedure. Programming and Relearning
18. Check for Temporary DTCs or DTCs with the HDS.

Are any Temporary DTCs or DTCs indicated?

YES - If DTC P0096 is indicated, check for poor connections or loose terminals at IAT sensor 2 and the PCM, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.

NO - Troubleshooting is complete.
