NOTE: 

• Before you troubleshoot, review the general troubleshooting information .
• Check for damage or corrosion at ECT sensor 1 connector terminals.

DTC (PGM-FI)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   Clear DTC

   -3. Start the engine.

   Is DTC P0119 indicated?

   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 ECT sensor 1 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. Shorted wire check (TW 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 connectors.

   ECT sensor 1 2P connector

   PCM connector No. 1 (96P)

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

   Test condition	Vehicle OFF (LOCK) mode
   	ECT sensor 1 2P connector: disconnected
   	PCM connector No. 1 (96P): disconnected
   Test point 1	ECT sensor 1 2P connector (female terminals) No. 2:
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short in the TW wire between PCM connector No. 1 terminal No. 49 and ECT sensor 1.

   NO 

   The TW wire is not shorted. Go to step 3.

3. Open wire check (TW line)

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

   Test condition	Vehicle OFF (LOCK) mode
   	ECT sensor 1 2P connector: disconnected
   	PCM connector No. 1 (96P): disconnected
   Test point 1	ECT sensor 1 2P connector (female terminals) No. 2:
   Test point 2	PCM connector No. 1 (96P) No. 49

   Is there continuity?

   YES 

   The TW wire is OK. Go to step 4.

   NO 

   Repair an open in the TW wire between PCM connector No. 1 terminal No. 49 and ECT sensor 1.

4. Open wire check (SG3 line)

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

   Test condition	Vehicle OFF (LOCK) mode
   	ECT sensor 1 2P connector: disconnected
   	PCM connector No. 1 (96P): disconnected
   Test point 1	ECT sensor 1 2P connector (female terminals) No. 1:
   Test point 2	PCM connector No. 1 (96P) No. 91

   Is there continuity?

   YES 

   The SG3 wire is OK. Replace ECT sensor 1 .

   NO 

   Repair an open in the SG3 wire between PCM connector No. 1 terminal No. 91 and ECT sensor 1.
