Commonly affected vehicles include the 2010-2015 Chevrolet Silverado, 2012-2016 Honda Civic, and 2006-2010 Ford Fusion. Check for any recalls or service bulletins regarding the IAT sensor in your vehicle.
How can I prevent P0113 from happening again?
Regular maintenance, including checking and replacing air filters, inspecting wiring and connectors, and ensuring proper airflow to the engine, can help prevent the P0113 code from reappearing.
What is P0113?
The DTC code P0113 indicates a high input from the intake air temperature (IAT) sensor, which is crucial for managing engine performance and fuel efficiency. This code often appears in various vehicles, including popular models like the 2010-2015 Chevrolet Silverado and the 2012-2016 Honda Civic. The IAT sensor measures the temperature of the air entering the engine and sends this information to the engine control unit (ECU). When the ECU detects a voltage reading from the IAT sensor that is higher than expected, it triggers the P0113 code. This can lead to incorrect air-fuel mixture calculations, potentially causing performance issues, increased emissions, and poor fuel economy. Drivers might notice symptoms such as rough idling, a decrease in acceleration, or even stalling in more severe cases. Ignoring this code can result in long-term engine damage, making it important to address promptly. Proper diagnosis often requires checking the sensor wiring, ensuring there are no shorts or open circuits, and testing the sensor itself using tools like a multimeter or the GeekOBD APP. Understanding this code will help car owners take the right steps to resolve the issue effectively.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0113 is present:
- Check engine light stays on constantly, indicating an ongoing issue that needs immediate attention.
- Engine hesitates during acceleration, making it difficult to maintain speed or respond quickly to throttle input.
- Fuel economy decreased by 10-15%, leading to unexpected expenses at the pump.
- Rough idling, where the engine feels unstable and may stall if not given enough throttle.
- Poor engine performance, characterized by sluggishness, particularly noticeable during rapid acceleration.
Possible Causes
Most common causes of P0113 (ordered by frequency):
- Faulty IAT sensor – a common cause of P0113, occurring in about 60% of cases. A defective sensor cannot accurately measure air temperature, leading to incorrect readings sent to the ECU.
- Damaged wiring or connectors – this can lead to shorts or open circuits that disrupt the signal from the IAT sensor. It’s essential to inspect the wiring for frays or corrosion.
- Poor air intake system – restricted airflow due to a dirty air filter or damaged intake can affect sensor readings. Regular maintenance can help prevent this issue.
- ECU malfunction – while rare, a faulty ECU can misinterpret sensor data, leading to a P0113 code. This requires professional diagnosis and potential ECU replacement.
- Extreme environmental conditions – such as heavy rain or flooding can affect sensor performance, though this is less common.
