Understanding Honda DTC P0113: A Comprehensive Guide
Honda DTC P0113 is a diagnostic trouble code indicating an issue with the Intake Air Temperature (IAT) Sensor Circuit. This code appears when the engine control module (ECM) detects an unusually high voltage from the IAT sensor, suggesting the intake air temperature is much lower than realistically possible. The IAT sensor plays a crucial role in engine management, helping the ECM adjust fuel mixture and ignition timing for optimal performance.
Common Symptoms of Honda DTC P0113:
1. Illuminated Check Engine Light
2. Decreased fuel efficiency
3. Engine rough idling or stalling
4. Starting difficulties, especially in cold weather
5. Reduced engine performance
6. Possible black exhaust smoke
These symptoms occur because the faulty IAT sensor readings cause the ECM to miscalculate the air-fuel mixture, leading to suboptimal engine operation.
Causes of Honda DTC P0113:
1. Malfunctioning IAT sensor
2. Damaged, corroded, or loose wiring in the IAT sensor circuit
3. Engine Control Module faults
4. Extreme weather conditions (rarely)
5. Sensor contamination by dirt, oil, or other substances
Diagnosing and Fixing Honda DTC P0113:
1. Use an OBD-II scanner to confirm the code and check for related codes
2. Inspect the IAT sensor and wiring for visible damage or corrosion
3. Clean the IAT sensor using electronic cleaner spray and a soft brush
4. Check and repair any damaged wiring or loose connections
5. Replace the IAT sensor if cleaning doesn’t resolve the issue
6. Clear the code and test to ensure the problem is fixed

Preventing Future Honda DTC P0113 Issues:
1. Follow Honda’s recommended maintenance schedule
2. Keep the engine bay clean, especially around the IAT sensor and air intake
3. Use high-quality OEM or equivalent parts when replacements are necessary
4. Avoid water damage by being cautious when driving through deep water or using pressure washers
5. Address engine performance issues promptly
While many Honda owners can tackle the P0113 issue themselves, don’t hesitate to seek professional help if you’re unsure about any step in the diagnosis or repair process. Regular maintenance and prompt attention to warning signs can prevent many issues, including the P0113 code, from occurring in the first place.
