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):

?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 on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot.?
     
NO
