Code P0097 Buick Description
The P0097 Buick code indicates a problem with the Intake Air Temperature Sensor 2 Circuit being too low. The Intake Air Temperature Sensor (IAT) is a crucial component of the engine management system, responsible for measuring the temperature of the air entering the engine. This information is used by the Engine Control Module (ECM) to adjust the air-fuel mixture for optimal combustion. When the IAT Sensor 2 Circuit registers a low voltage, it means that the temperature reading is lower than expected, which can lead to incorrect fuel delivery and affect the engine's performance.
Common Causes of P0097 Buick
- Faulty Intake Air Temperature Sensor 2
- Damaged wiring or connectors in the sensor circuit
- Malfunctioning Engine Control Module (ECM)
- Issues with the air intake system
- Environmental factors affecting sensor readings
Symptoms of P0097 Buick
- Decreased fuel efficiency
- Rough idling or stalling
- Hesitation during acceleration
- Check Engine Light illuminated
- Engine running too rich or too lean
How to Fix P0097 Buick
- Begin by diagnosing the issue using a scan tool to confirm the P0097 code and identify the specific problem.

Discuss the causes and fixes for P0097 Buick OBDII Code
-
P0097 is when you pull the plug on a mass air flow sensors?
That’s what I did and I immediately got P0097 along with a P0102. -
Yes, since Intake Air Temperature Sensor is part of the Mass Air Flow (MAF) sensor, if you disconnect the MAF plug then both code will set.
