P0097 Acura Code - Intake Air Temperature Sensor 2 Circuit Low Input
Quick Answer
The Intake Air Temperature (IAT) Sensor 2 is a thermistor that detects intake air temperature, and it is used for air/fuel ratio feedback control to compensate for the atmospheric density fluctuations that accompany changes in intake air temperature. Common causes include Faulty Intake Air Temperature Sensor 2, Intake Air Temperature Sensor 2 harness is open or shorted, Intake Air Temperature Sensor 2 circuit poor electrical connection. 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 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.
