P2199 2016 GMC Sierra Code - Intake Air Temperature Sensor 1-2 Not Plausible
Quick Answer
The following sensors are integrated within the Mass Air Flow/Multifunction Intake Air Sensor: IAT sensor 1, IAT sensor 2, Humidity sensor, MAF sensor, and BARO pressure sensor. Common causes include Faulty Intake Air Temperature (IAT) (integrated within Mass Air Flow/Multifunction Intake Air Sensor), Intake Air Temperature harness is open or shorted, Intake Air Temperature 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 P2199 2016 GMC Sierra Description
The Intake Air Temperature (IAT) Sensor is a variable resistor that changes the voltage on the Engine Control Module (ECM) supplied 5 V signal circuit. The signal varies with the inlet air temperature in the sensor bore. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the absolute difference between the IAT sensor 1 and the IAT sensor 2 temperatures is greater than 55°C (99°F) for longer than 5 s.
What are the Possible Causes of the DTC P2199 2016 GMC Sierra?
- Faulty Intake Air Temperature (IAT) (integrated within Mass Air Flow/Multifunction Intake Air Sensor)
- Intake Air Temperature harness is open or shorted
- Intake Air Temperature circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P2199 2016 GMC Sierra?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P2199 2016 GMC Sierra code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
