P0096 IAT Sensor 2 Circuit Range/Performance Problem
     

1.
Connector visual check:

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):

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.

?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
     
     
     
     
NO
     
     
     
Go to step 3.
3.
IAT sensor 2 performance check (high temperature):

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.

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
