DTC P0096

DTC P0096  : IAT Sensor 2 Circuit Range/Performance Problem

DTC (PGM-FI)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Check the parameter(s) below with the HDS.

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   Intake Air Sensor Voltage	Less than 0.20	V

   Data List

   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 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. Determine possible failure area (IAT sensor 2, others)

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

   -2. Disconnect the following connector.

   IAT sensor 2 2P connector

   -3. Turn the vehicle to the ON mode.

   -4. Check the parameter(s) below with the HDS.

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   Intake Air Sensor Voltage	Less than 0.20	V

   Data List

   Do the current condition(s) match the threshold?

   YES 

   Go to step 3.

   NO 

   Replace IAT sensor 2 .

3. Shorted wire check (IAT2(INTA) line)

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

   -2. Jump the SCS line with the HDS, and wait more than 1 minute.

   -3. Disconnect the following connector.

   PCM connector E (80P)

   -4. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	IAT sensor 2 2P connector: disconnected
   	PCM connector E (80P): disconnected
   Test point 1	IAT sensor 2 2P connector (female terminals) No. 1:
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short in the IAT2(INTA) wire between the PCM (E55) and IAT sensor 2.

   NO 

   The IAT2(INTA) wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM , then recheck. If DTC P0096 goes away and the PCM was substituted, replace the original PCM .
