  • Access the IAT PID.
  • Connect a jumper wire between MAF/IAT sensor terminals D and E (harness-side).
  • Verify the IAT value.
  • Is the voltage below 4.9 V? 
 Yes Replace the MAF/IAT sensor, then go to Step 9.
No Go to the next step.
5 INSPECT IAT SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY 
  • Turn ignition switch to the ON position (Engine off).

  • Disconnect PCM connector.
  • Inspect PCM terminals 2V and 2H (harness-side) for tightness using a feeler tool.
  • Is there any malfunction?
 Yes Repair or replace the terminal, then go to Step 9.
No Go to the next step.
7 INSPECT IAT SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT 
  • Inspect for continuity between MAF/IAT sensor terminal D (harness-side) and PCM terminal 2V (harness-side).
  • Is there continuity?
 Yes Go to the next step.
No Repair or replace the wiring harness for an open circuit, then go to Step 9.
8 INSPECT IAT SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT 
  • Inspect for continuity between MAF/IAT sensor terminal E (harness-side) and PCM terminal 2H (harness-side).
  • Is there continuity?
 Yes Go to the next step.
No Repair or replace the wiring harness for an open circuit, then go to the next step.
9 VERIFY TROUBLESHOOTING OF DTC P0113 COMPLETED 
  • Make sure to reconnect all disconnected connectors.
  • Turn ignition switch to the ON position (Engine off).
  • Clear the DTC from the PCM memory using the WDS or equivalent.
  • Start the engine and warm it up completely.
  • Is same DTC present?
 Yes Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION ).
No Go to the next step.
10 VERIFY AFTER REPAIR PROCEDURE
