  • Verify related Service Bulletins and/or on-line repair information availability.
  • Is any related Service Bulletins available?
 Yes Perform repair or diagnosis according to the available Service Bulletins.
  • If the vehicle is not repaired, go to the next step.
No Go to the next step.
3 INSPECT IAT SENSOR CONNECTOR FOR POOR CONNECTION 
  • Switch the ignition to off.
  • Disconnect MAF/IAT sensor connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
  • Are there any malfunction?
 Yes Repair or replace suspected part, then go to Step 9.
No Go to the next step.
4 CLASSIFY IAT SENSOR MALFUNCTION OR HARNESS MALFUNCTION 
  • Disconnect the MAF/IAT sensor connector.
  • Switch the ignition to ON (Engine off).
  • Measure voltage between MAF/IAT sensor terminal F (wiring harness-side) and body ground.
  • Is voltage 4.5-5.5 V  ?
 Yes Inspect the IAT sensor.
(See INTAKE AIR TEMPERATURE (IAT) SENSOR INSPECTION .)
Replace if necessary, then go to Step 9.
No Go to the next step.
5 INSPECT IAT SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY 
  • Switch the ignition to ON (Engine off).
  • Measure voltage between MAF/IAT sensor terminal F (wiring harness-side) and body ground.
  • Is voltage B+  ?
 Yes Repair or replace suspected part, then go to Step 9.
No Go to the next step.
6 INSPECT PCM CONNECTOR FOR POOR CONNECTION 
  • Switch the ignition to off.
  • Disconnect the PCM connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
  • Are there any malfunction?
 Yes Repair or replace suspected part, then go to Step 9.
No Go to the next step.
7 INSPECT IAT SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT 
  • Inspect continuity between MAF/IAT sensor terminal F (wiring harness-side) and PCM terminal 1P (wiring harness-side).
  • Is there continuity?
 Yes Go to the next step.
No Repair or replace suspected part, then go to Step 9.
8 INSPECT IAT SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT 
  • Inspect continuity between MAF/IAT sensor terminal E (wiring harness-side) and PCM terminal 1AT (wiring harness-side).
  • Is there continuity?
 Yes Go to the next step.
No Repair or replace suspected part, then go to the next step.
9 VERIFY TROUBLESHOOTING OF DTC P0113:00 HAS BEEN COMPLETED 
  • Verify that all disconnected connectors reconnected.
  • Switch the ignition to ON (Engine off).
  • Clear the DTC from the PCM memory using the M-MDS.
  • Start engine and warm it up completely.
  • Is same DTC present?
 Yes Repeat the inspection from Step 1.

Go to the next step.
No Go to the next step.
10 VERIFY AFTER REPAIR PROCEDURE 
 Yes Go to the applicable DTC inspection.
(See DTC TABLE .)
No Troubleshooting completed.
