OBD2 Automotive Error Code P0113: How to Fix It

Q: What causes OBD2 code P0113 to appear?

Code P0113 is typically caused by a faulty intake air temperature sensor, damaged wiring or connectors, air intake leaks, or contamination on the sensor element. In rare cases, it can be caused by engine overheating or ECM issues.

Q: Can I drive with error code P0113?

You can drive short distances with P0113, but it's not recommended for extended periods. The error can cause poor fuel economy, rough idling, and reduced performance. The engine may run in a default mode that could cause long-term damage if not addressed.

Q: How much does it cost to fix P0113?

If it's just a dirty sensor, cleaning costs nothing. A replacement IAT sensor typically costs $20-80. Professional diagnosis and repair can range from $100-300 depending on labor rates and whether additional components need replacement.

Q: Will P0113 clear itself?

No, P0113 will not clear itself. Even if the underlying problem is temporarily fixed, the code remains stored in the ECM until manually cleared with an OBD2 scanner or the battery is disconnected for an extended period.

Q: How do I prevent P0113 from happening again?

Regular maintenance helps prevent P0113. Keep your air filter clean, inspect intake components during routine service, and avoid using aftermarket air intake modifications that might affect sensor readings. Address any engine overheating issues promptly.

Abstract

OBD2 error code P0113 indicates that your vehicle's intake air temperature (IAT) sensor is reading abnormally high temperatures, typically above 300°F when the engine is cold. This sensor helps your engine's computer determine the proper air-fuel mixture, and when it malfunctions, you may experience poor performance, rough idling, or reduced fuel economy.
