Code P0097 2017 GMC Sierra Description
The P0097 diagnostic trouble code (DTC) for a 2017 GMC Sierra relates to the Intake Air Temperature Sensor 2 Circuit Low. This code indicates that the engine control module (ECM) has detected a lower than expected voltage coming from the intake air temperature sensor 2, which is located in the air intake system of the vehicle. The intake air temperature sensor plays a crucial role in monitoring the temperature of the air entering the engine, which is essential for determining the air-fuel mixture and ignition timing for optimal engine performance.
Common Causes of P0097 2017 GMC Sierra
- Faulty Intake Air Temperature Sensor 2: The sensor itself may be malfunctioning, providing incorrect readings to the ECM.
- Wiring or Connector Issues: Corrosion, damage, or loose connections in the wiring harness or connector related to the intake air temperature sensor can cause circuit low issues.
- ECM Malfunction: A malfunctioning engine control module may not be interpreting the sensor data correctly, leading to the P0097 code.
- Intake Air Leaks: Any leaks in the intake air system can affect the sensor readings and trigger the code.
- Extreme Temperature Conditions: Exposure to extreme heat or cold can also affect the sensor's performance and trigger the code.
Symptoms of P0097 2017 GMC Sierra
- Check Engine Light: The most common symptom associated with the P0097 code is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Fuel Efficiency: A malfunctioning intake air temperature sensor can lead to incorrect fuel mixture adjustments, resulting in decreased fuel efficiency.
- Rough Idling: The engine may experience rough idling or erratic idle speeds due to incorrect air-fuel mixture adjustments.
- Hesitation During Acceleration: The vehicle may hesitate or stumble during acceleration, affecting its overall performance.
- Stalling: In severe cases, the engine may stall or shut off unexpectedly, causing potential safety hazards.
How to Fix P0097 2017 GMC Sierra
- Diagnose the Issue: Use a scan tool to retrieve the P0097 code and perform a visual inspection of the intake air temperature sensor 2, wiring, and connectors.
- Test the Sensor: Measure the sensor's resistance and compare it to the manufacturer's specifications to determine if it is faulty.
- Check Wiring and Connector: Inspect the wiring harness and connector for any damage, corrosion, or loose connections. Repair or replace as necessary.
- Replace Intake Air Temperature Sensor 2: If the sensor is determined to be faulty, replace it with a new one following manufacturer recommendations.
- Clear the Code: Clear the DTC with a scan tool after completing the repair to reset the check engine light and monitor the vehicle for any recurring issues.
Cost to Fix P0097 2017 GMC Sierra
The typical repair costs for addressing the P0097 code on a 2017 GMC Sierra can vary depending on the specific cause of the issue and the cost of parts and labor. In general, the cost of a new intake air temperature sensor 2 can range from $50 to $100, while the labor cost for diagnosis and replacement can range from $100 to $200. Overall, the total repair cost for this issue may fall between $150 and $300. It is important to note that these estimates are rough guidelines, and actual costs may vary based on the location, vehicle make and model, and labor rates at auto repair shops. Additionally, additional diagnosis time may be needed if there are underlying issues contributing to the P0097 code.

Frequently Asked Questions about P0097 2017 GMC Sierra Code
1. What does the OBDII code P0097 mean on a 2017 GMC Sierra?
P0097 indicates that the Powertrain Control Module (PCM) has detected a low voltage signal from the Intake Air Temperature (IAT) Sensor 2 circuit.
2. What are the common symptoms of code P0097 on a 2017 GMC Sierra?
Symptoms may include poor engine performance, reduced fuel efficiency, rough idling, hesitation during acceleration, or the Check Engine Light being illuminated.
3. What causes the P0097 code on a 2017 GMC Sierra?
Common causes include a faulty Intake Air Temperature Sensor 2, damaged wiring or connectors in the IAT sensor circuit, or a malfunctioning PCM.
4. Can I drive my 2017 GMC Sierra with the P0097 code present?
While you may still be able to drive, doing so could lead to poor performance and further engine issues. It's best to address the issue promptly.
5. How do I diagnose the P0097 code on my 2017 GMC Sierra?
Start by visually inspecting the IAT sensor and its wiring for damage or corrosion. Use a scan tool to read live data and test the sensor's voltage and resistance levels.
6. How do I fix the P0097 code on a 2017 GMC Sierra?
Repairs may include replacing the IAT sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming/updating the PCM if needed.
7. Where is the Intake Air Temperature Sensor 2 located on a 2017 GMC Sierra?
IAT Sensor 2 is typically located in the intake manifold or near the throttle body, downstream from the air filter housing.
8. How much does it cost to fix the P0097 code on a 2017 GMC Sierra?
Repair costs can vary. Replacing an IAT sensor may cost $50–$150 for parts, plus labor. Wiring or PCM repairs can be more expensive.
