## DTC Troubleshooting: P0113 (10-2)

DTC P0113 (10-2): | IAT Sensor Circuit High Voltage

1. | Turn the ignition switch ON (II).

2. | Check the IAT with the scan tool. Is -20°C (-4°F) or less (or L-Limit in Honda mode of PGM Tester) or 5 V indicated? YES - Go to 3. NO - Intermitent failure, system is OK at this time. Check for poor connections or loose wires at the IAT sensor and at the ECM/ PCM.n

3. | Turn the ignition switch OFF.

4. | Disconnect the IAT sensor 2P connector.

5. | Connect the IAT sensor 2P connector terminals No. 1 and No. 2 with a jumper wire.

6. | Turn the ignition switch ON (II).

7. | Check the IAT with the scan tool. Is -20°C (-4°F) or less (or L-Limit in Honda mode of PGM Tester) or 5 V indicated? YES - Go to 8. NO - Replace the IAT sensor.n

8. | Turn the ignition switch OFF.

9. | Remove the jumper wire.

10. | Connect ECM/PCM connector terminals A10 and B17 with a jumper wire.

11. | Turn the ignition switch ON (II).

12. | Check the IAT with the scan tool. Is -20°C (-4°F) or less (or L-Limit in Honda mode of PGM Tester) or 5 V indicated? YES - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.n NO - Repair open in the wire between the ECM/PCM (A10, B17) and the IAT sensor.n
