| P0097 IAT Sensor 2 Circuit Low Voltage |
DTC (PGM-FI)
- 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 IAT Sensor (2) Less than 0.08 V 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 .
- 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 IAT Sensor (2) Less than 0.08 V Do the current condition (s) match the threshold?
YES
Go to step 3.
NO
- Shorted wire check (ITA2 (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 ITA2 (INTA) wire between the PCM (E55) and IAT sensor 2.
NO
The ITA2 (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 .
