Code P0097 Acura Description
The P0097 diagnostic trouble code (DTC) for Acura vehicles specifically refers to the Intake Air Temperature Sensor 2 Circuit Low Input. This code indicates that the engine control module (ECM) has detected a lower than expected voltage signal from the intake air temperature sensor 2. The intake air temperature sensor is a crucial component that measures the temperature of the air entering the engine. This information is used by the ECM to adjust fuel delivery and ignition timing for optimal engine performance and efficiency.
Common Causes of P0097 Acura
- Faulty intake air temperature sensor 2
- Wiring or connector issues in the intake air temperature sensor circuit
- ECM software issues
- Intake air leaks near the sensor
- Extreme temperature conditions affecting sensor performance
Symptoms of P0097 Acura
- Decreased fuel efficiency
- Rough idling or engine stalling
- Hesitation during acceleration
- Decreased engine performance
- Check Engine Light illuminated
How to Fix P0097 Acura
- Begin by visually inspecting the wiring and connector of the intake air temperature sensor 2 for any signs of damage or corrosion. Repair or replace as necessary.
- Test the intake air temperature sensor 2 using a multimeter to check for proper voltage readings. Replace the sensor if it is faulty.
- Clear the DTC using an OBD-II scanner and see if it returns after driving the vehicle.
- If the code persists, check for any intake air leaks near the sensor and repair them.
- If all else fails, consult a professional mechanic to diagnose and repair any underlying issues with the ECM or other related components.
Cost to Fix P0097 Acura
The typical repair costs for addressing the P0097 code on an Acura vehicle can vary depending on the specific cause of the issue. In general, the cost of replacing the intake air temperature sensor 2 can range from $50 to $150, while labor costs can range from $80 to $150 per hour. Additional costs may be incurred if wiring repairs or ECM diagnostics are needed. It's recommended to consult with a local auto repair shop for a more accurate estimate based on your vehicle's make and model.

Frequently Asked Questions about P0097 Acura Code
1. What does the OBDII code P0097 mean on an Acura?
P0097 indicates a problem with the Intake Air Temperature Sensor 2 (IAT2) circuit, specifically that the sensor is reporting a voltage input lower than the expected range.
2. What are the common symptoms of P0097 on an Acura?
Symptoms may include poor engine performance, reduced fuel efficiency, difficulty starting the engine, and the check engine light illuminating.
3. What causes the P0097 code on an Acura?
Common causes include a faulty IAT2 sensor, damaged wiring or connectors, a short circuit, or issues with the engine control module (ECM).
4. Can I drive my Acura with a P0097 code?
While it may be possible to drive, it's not recommended as it can lead to poor engine performance and potentially cause further damage over time.
5. How do I fix the P0097 code on my Acura?
Start by inspecting the IAT2 sensor, wiring, and connectors for damage or corrosion. Replace the sensor or repair the wiring if necessary. Clear the code and test the system.
6. Where is the Intake Air Temperature Sensor 2 located on an Acura?
The IAT2 sensor is typically located in the intake manifold or near the air filter housing, depending on the model.
7. How much does it cost to fix a P0097 code on an Acura?
Repair costs can vary, but replacing the IAT2 sensor typically ranges from $50 to $200, depending on labor and parts.
8. Can a dirty air filter cause a P0097 code on an Acura?
A dirty air filter is unlikely to directly cause this code, but it can contribute to airflow issues that may indirectly affect sensor readings.
9. How can I prevent the P0097 code from reoccurring on my Acura?
Regularly inspect and maintain the intake system, including cleaning or replacing the air filter, and ensure all electrical connections are secure and free of corrosion.
10. Will replacing the IAT2 sensor always fix the P0097 code on an Acura?
Not always. If the issue lies in the wiring, connectors, or ECM, replacing the sensor alone will not resolve the problem. Always diagnose the full circuit before replacing parts.
