OBD-II Generic Error Code P0113: How to Fix It

Q: Can I drive with error code P0113?

You can drive short distances, but it may cause poor fuel economy and reduced performance. It's best to fix it promptly to avoid potential damage to the catalytic converter.

Q: Is P0113 the same as P0112?

No. P0113 means high input (high voltage), indicating an open circuit or faulty sensor. P0112 means low input (low voltage), indicating a short circuit or sensor failure.

Q: Where is the IAT sensor located?

The IAT sensor is typically located in the intake air duct, between the air filter and the throttle body, or integrated into the mass airflow (MAF) sensor.

Q: How much does it cost to fix P0113?

If you replace the sensor yourself, a new IAT sensor costs $20-$50. If a mechanic does it, labor may add $50-$100 depending on the vehicle.

Q: Can I clean the IAT sensor instead of replacing it?

While you can clean the sensor with MAF cleaner, P0113 usually indicates an electrical issue like an open circuit, so cleaning rarely fixes it. Replacement is often needed.

Abstract

Error code P0113 means the Engine Control Module (ECM) has detected a high voltage signal from the Intake Air Temperature (IAT) sensor, indicating a potential open circuit, short to power, or a faulty sensor. This can cause poor fuel economy and drivability issues.
