DTC P0095

DTC P0095  : IAT Sensor 2 Out of Range

NOTE:  Before you troubleshoot, review the general troubleshooting information .

DTC (PGM-FI)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   Clear DTC

   -3. Check the parameter(s) below with the HDS.

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   IAT Sensor (2)	More than 264.31	deg.F
   	More than 129.06	deg.C

   Do the current condition(s) match the threshold?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at MAP sensor/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 .

2. IAT sensor 2 circuit connectors and terminals condition check

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

   Check for poor connections or loose terminals at these locations:

   • MAP sensor/IAT sensor 2
   • PCM
   • Engine ground
   • Body ground

   Are the connections and terminals OK?

   YES 

   Go to step 3.

   NO 

   Repair the connections or terminals.

3. Shorted wire check (TA line to power)

   -1. Jump the SCS line with the HDS, and wait more than 1 minute.

   -2. Disconnect the following connectors.

   MAP sensor/IAT sensor 2 4P connector

   PCM connector No. 1 (96P)

   -3. Turn the vehicle to the ON mode.

   -4. Measure the voltage between test points 1 and 2.

   Test condition	Vehicle ON mode
   	MAP sensor/IAT sensor 2 4P connector: disconnected
   	PCM connector No. 1 (96P): disconnected
   Test point 1	MAP sensor/IAT sensor 2 4P connector (female terminals) No. 2:
   Test point 2	Body ground

   Is there any voltage?

   YES 

   Repair a short to power in the TA wire between PCM connector No. 1 terminal No. 45 and MAP sensor/IAT sensor 2.

   NO 

   The TA wire is OK. Replace MAP sensor/IAT sensor 2 .
