Code P2199 2016 Chevrolet Silverado 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 Chevrolet Silverado?
- 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)
