Code P0097 Toyota Description
The P0097 diagnostic trouble code (DTC) for Toyota 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 Toyota
- Faulty intake air temperature sensor 2
- Wiring issues or poor electrical connections
- ECM software or hardware issues
- Intake air leaks near the sensor
- Extreme temperature conditions affecting sensor readings
Symptoms of P0097 Toyota
- Check Engine Light illuminated on the dashboard
- Decreased fuel efficiency
- Rough idling or engine misfires
- Hesitation or lack of power during acceleration
- Engine stalling or difficulty starting
How to Fix P0097 Toyota
- Begin by diagnosing the issue using a scan tool to confirm the P0097 code and pinpoint the faulty intake air temperature sensor 2.
- Locate the intake air temperature sensor 2, typically located near the air intake manifold or air filter housing.
- Inspect the sensor and wiring for any visible damage or corrosion. Replace the sensor if necessary.
- Clear the DTC with a scan tool and test drive the vehicle to ensure the code does not return and that the engine operates correctly.
- If the issue persists, further diagnosis may be required to check for wiring issues, ECM malfunctions, or other potential causes.
Cost to Fix P0097 Toyota
The cost of repairing the P0097 code for the Intake Air Temperature Sensor 2 Circuit Low Input can vary depending on the specific vehicle make and model, as well as the location and labor rates of the auto repair shop.

Frequently Asked Questions about P0097 Toyota Code
1. What does the OBDII code P0097 mean on a Toyota?
P0097 indicates that the Engine Control Module (ECM) has detected a low voltage input from the Intake Air Temperature (IAT) Sensor 2 circuit, which measures incoming air temperature.
2. What are the symptoms of the P0097 code on a Toyota?
Common symptoms include poor engine performance, reduced fuel efficiency, difficulty starting the engine, and sometimes an illuminated Check Engine Light.
3. What causes the P0097 code in a Toyota?
Possible causes include a faulty IAT Sensor 2, damaged wiring or connectors, an open or short circuit in the sensor circuit, or a malfunctioning ECM.
4. Can I drive my Toyota with the P0097 code?
While the car may still be drivable, continuing to drive with this code can lead to reduced performance and may cause further damage to the engine or emissions system.
5. How do I diagnose the P0097 code on a Toyota?
Diagnosis involves using an OBDII scanner to confirm the code, visually inspecting the IAT sensor and its wiring, testing the sensor's resistance with a multimeter, and checking for circuit continuity.
6. How do I fix the P0097 code on a Toyota?
Repairs may include replacing the IAT Sensor 2, repairing or replacing damaged wiring or connectors, or addressing any issues with the ECM if necessary.
7. Where is the IAT Sensor 2 located on a Toyota?
The IAT Sensor 2 is often located in the intake manifold or air intake system, but the exact location may vary depending on the vehicle model.
8. How much does it cost to fix the P0097 code on a Toyota?
The repair cost can range from $50 to $200, depending on whether you need to replace the IAT sensor or repair wiring. Labor costs may vary as well.
9. Can a dirty air filter cause the P0097 code on a Toyota?
A dirty air filter is unlikely to cause the code directly, but it can contribute to airflow issues that may affect sensor readings.
10. Will clearing the P0097 code fix the issue on my Toyota?
Clearing the code will turn off the Check Engine Light temporarily, but the underlying issue must be addressed to prevent the code from returning.

Good afternoon,
Yesterday my RAV 4 III turned on the engine light and not off. The machine 's diagnosis said to be the P0097 error , how to solve this problem?
thank you
-
What year is your RAV4? More than likely you have to replace the Mass Air Flow (MAF) sensor
-
What engine size 4 o 6 cylinders?
Unfortunately I can't find ay information on the factory service manual about that code. Please double check the code.The Intake Air Temperature (IAT) Sensor is part of the Mass Air Flow (MAF) sensor.
