P0097 Buick 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.

Code P0097 Buick Description

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. The signal varies with inlet air temperature in the sensor bore and is displayed by the scan tool as °C (°F). The IAT sensor 2 and the humidity sensor share the same circuit. The IAT sensor 2 signal is displayed by the scan tool as Hertz (Hz) and °C (°F). The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the IAT sensor 2 signal is intermittent or has abruptly changed for longer than 5 s.

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.
