P0113 Acura Code - Intake Air Temperature Sensor 1 Circuit High Voltage
Quick Answer
The P0113 code for Acura vehicles indicates that there is a high voltage condition in the Intake Air Temperature (IAT) Sensor 1 circuit. Common causes include Faulty IAT Sensor: The sensor itself may be malfunctioning, causing it to send incorrect voltage readings to the ECM, Wiring Issues: Damaged or corroded wiring in the IAT sensor circuit can lead to high voltage readings, Poor Connection: Loose or poor connections at the sensor or ECM can cause voltage fluctuations. 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.

Code P0113 Acura Description
The P0113 code for Acura vehicles indicates that there is a high voltage condition in the Intake Air Temperature (IAT) Sensor 1 circuit. The IAT sensor is responsible for monitoring the temperature of the air entering the engine. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal performance and efficiency. When the voltage in the IAT sensor circuit is higher than expected, it can lead to incorrect readings and negatively impact the engine's performance.
Common Causes of P0113 Acura
- Faulty IAT Sensor: The sensor itself may be malfunctioning, causing it to send incorrect voltage readings to the ECM.
- Wiring Issues: Damaged or corroded wiring in the IAT sensor circuit can lead to high voltage readings.
- Poor Connection: Loose or poor connections at the sensor or ECM can cause voltage fluctuations.
- ECM Malfunction: A malfunctioning ECM can also be a potential cause of high voltage in the IAT sensor circuit.
- Intake Air Temperature Fluctuations: Extreme temperature fluctuations in the intake air can also trigger this code.
Symptoms of P0113 Acura
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Decreased Fuel Efficiency: A faulty IAT sensor can cause the engine to run rich or lean, leading to a decrease in fuel efficiency.
- Engine Stalling: In some cases, the engine may stall or have difficulty starting due to incorrect air-fuel mixture.
- Rough Idle: The engine may experience rough idling or hesitation during acceleration.
- Poor Performance: Overall, the vehicle may exhibit decreased performance and responsiveness.
How to Fix P0113 Acura
- Diagnostic: Use a diagnostic tool to confirm the P0113 code and pinpoint the exact cause of the issue.
- Inspect Wiring: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test IAT Sensor: Test the IAT sensor using a multimeter to determine if it is providing accurate readings. Replace if necessary.
- Check ECM: Ensure that the ECM is functioning properly and reprogram if needed.
- Clear Codes: Clear the code from the ECM memory and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P0113 Acura
The typical repair cost for addressing a P0113 code in an Acura vehicle can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor. Keep in mind that diagnosis time and labor rates at auto repair shops can vary, so it's recommended to get a personalized estimate from a trusted mechanic.

Frequently Asked Questions about P0113 Acura Code
1. What does the OBDII code P0113 mean on an Acura?
P0113 indicates that the Intake Air Temperature (IAT) Sensor 1 is reporting a high voltage signal to the engine control module (ECM), suggesting an abnormally high air temperature or a circuit issue.
2. What are the common symptoms of a P0113 code in an Acura?
Symptoms may include poor fuel efficiency, rough idling, reduced engine performance, hard starting, or the check engine light being illuminated.
3. What causes the P0113 code to appear in an Acura?
Common causes include a faulty IAT sensor, a damaged or corroded sensor connector, a shorted or open wiring harness, or a malfunctioning ECM.
4. Can I drive my Acura with a P0113 code?
While it may be safe to drive short distances, ignoring this code can lead to poor performance, increased fuel consumption, and potential long-term engine damage.
5. How do I diagnose the P0113 code in my Acura?
Start by inspecting the IAT sensor and its connector for damage or corrosion, check the wiring for continuity, and test the sensor's resistance with a multimeter.
6. How do I fix the P0113 code on an Acura?
Repairs may involve cleaning or replacing the IAT sensor, repairing damaged wiring, reconnecting loose connectors, or updating/replacing the ECM if necessary.
7. Where is the Intake Air Temperature (IAT) sensor located on an Acura?
The IAT sensor is typically located in the air intake duct or integrated into the mass airflow (MAF) sensor, depending on the model.
8. How much does it cost to repair a P0113 code on an Acura?
Repair costs vary, but replacing the IAT sensor usually costs between $50 and $200, including parts and labor. Wiring repairs or ECM replacement could cost more.
9. Can a dirty air filter cause a P0113 code in an Acura?
A dirty air filter is unlikely to directly cause a P0113 code, but it may contribute to airflow issues that can affect sensor readings.
10. Will resetting the code clear the P0113 issue in my Acura?
Clearing the code with an OBDII scanner will turn off the check engine light temporarily, but the issue will return if the underlying problem isn’t fixed.
Discuss the causes and fixes for P0113 Acura OBDII Code
-
My Acura 03 RSX is throwing a p0113 code what is the first thing I should do to try and fix it
-
Start by checking the Intake Air Temperature (IAT) sensor connector, the connector should be firmly connected. If the connector is OK, then check the air filter, make sure is clean. If the connector nad air filter are OK, then you probably have to replace the sensor to fix the problem.
