P0097 2017 GMC Sierra Code - Intake Air Temperature Sensor 2 Circuit Low
Quick Answer
The Intake Air Temperature (IAT) sensor 1 is a variable resistor that changes the voltage on the Engine Control Module (ECM) supplied 5 V signal circuit. Common causes include Faulty Intake Air Temperature (IAT) sensor, Intake Air Temperature sensor harness is open or shorted, Intake Air Temperature sensor 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 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.
9. Can a dirty air filter cause code P0097 on a 2017 GMC Sierra?
While unlikely to directly cause P0097, a dirty air filter can affect airflow and sensor readings, potentially contributing to related issues.
10. How can I prevent the P0097 code from recurring on my 2017 GMC Sierra?
Regularly inspect and maintain the air intake system, keep connectors clean, and replace the IAT sensor or wiring as needed to prevent future issues.
