P0113 Subaru Code - Intake Air Temperature Circuit High Input
Quick Answer
The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. Common causes include Faulty Intake Air Temperature (IAT) sensor, Dirty air filter, Intake Air Temperature (IAT) sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Frequently Asked Questions about P0113 Subaru Code
1. What does the OBDII code P0113 mean on a Subaru?
P0113 indicates that the Intake Air Temperature (IAT) sensor is reporting a high voltage signal to the engine control module (ECM), suggesting a potentially faulty sensor or wiring issue.
2. What are the common symptoms of code P0113 in a Subaru?
Symptoms may include poor fuel efficiency, rough idling, engine hesitation, reduced engine performance, and the check engine light turning on.
3. What causes the P0113 code to appear on a Subaru?
Common causes include a faulty IAT sensor, damaged or corroded wiring, a disconnected sensor, or a malfunctioning ECM.
4. Can I drive my Subaru with the P0113 code active?
While the vehicle may still be drivable, it can result in reduced performance, poor fuel economy, and potential long-term engine damage if not addressed.
5. How do I diagnose a P0113 code on a Subaru?
Start by checking the IAT sensor and its wiring for visible damage, corrosion, or disconnection. Use a multimeter to test the sensor's resistance and voltage against manufacturer specifications.
6. How can I fix the P0113 code on my Subaru?
Repairs may involve replacing the IAT sensor, repairing or replacing damaged wiring, reconnecting loose connections, or, in rare cases, reprogramming or replacing the ECM.
7. Where is the IAT sensor located in a Subaru?
The IAT sensor is typically located on or near the intake manifold or within the air intake system, depending on your Subaru model.
8. How much does it cost to fix a P0113 code on a Subaru?
Costs can vary but typically range from $20 to $100 for a new IAT sensor, while labor costs may add $50 to $150 if performed by a mechanic.
9. Can a dirty air filter cause the P0113 code on a Subaru?
Indirectly, yes. A clogged air filter can affect airflow and cause the IAT sensor to send incorrect readings, though the sensor itself is usually the primary issue.
10. Will clearing the P0113 code with a scanner fix the issue on my Subaru?
Clearing the code may temporarily turn off the check engine light, but if the underlying issue isn’t resolved, the code will likely reappear.
