| 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 - Substitute a known-good ECM/PCM and recheck. If the symptom/indication goes away, replace the original ECM/ PCM.n NO - Repair open in the wire between the ECM/PCM (A10, B17) and the IAT sensor.n |
