P0097 2018 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 2018 GMC Sierra Code
1. What does the OBDII code P0097 mean on a 2018 GMC Sierra?
P0097 indicates a "Low Circuit Input" issue in Intake Air Temperature (IAT) Sensor 2, meaning the sensor is detecting a temperature signal that is lower than expected by the engine control module (ECM).
2. What are the common symptoms of P0097 on a 2018 GMC Sierra?
Symptoms may include poor engine performance, reduced fuel efficiency, hesitation during acceleration, and potentially an illuminated check engine light.
3. What causes the P0097 code to appear on a 2018 GMC Sierra?
Common causes include a faulty IAT Sensor 2, damaged or corroded wiring, a loose or disconnected sensor harness, or an ECM issue.
4. Where is the Intake Air Temperature Sensor 2 located on a 2018 GMC Sierra?
IAT Sensor 2 is typically located within or near the intake manifold or air intake tubing after the air filter.
5. Can a dirty air filter cause the P0097 code?
A dirty air filter is not a direct cause of P0097, but restricted airflow can affect the accuracy of the IAT sensor readings, potentially contributing to related issues.
6. How do I diagnose a P0097 code on a 2018 GMC Sierra?
Start by inspecting the IAT Sensor 2 and its wiring for damage, checking for loose connections, and testing the sensor’s resistance with a multimeter to ensure it’s functioning correctly.
7. Can I drive my 2018 GMC Sierra with a P0097 code?
Driving with a P0097 code is possible, but it’s not recommended as it can lead to poor fuel economy and may cause long-term engine performance issues.
8. How can I fix the P0097 code on my 2018 GMC Sierra?
Repairs may include replacing the faulty IAT Sensor 2, fixing damaged wiring, cleaning corroded connectors, or updating/reprogramming the ECM if needed.
9. How much does it cost to repair a P0097 code on a 2018 GMC Sierra?
Replacing the IAT Sensor typically costs $50-$150 for parts and labor, but costs may vary depending on the extent of wiring or ECM repairs needed.
10. Can a P0097 code trigger other trouble codes?
Yes, it can sometimes trigger related codes such as P0096 or other air/fuel mixture sensor codes due to interconnected systems.
