Code P16AA Chevrolet Description

The intake air heater has the ability to perform internal diagnostics for the temperature sensor circuit. The intake air heater monitors the internal temperature sensor voltage and if the voltage falls outside the calibrated threshold, the intake air heater sends a message to the Glow Plug Control Module (GPCM) and then the GPCM sends a message to the Engine Control Module (ECM) to set the appropriate Diagnostic Trouble Code (DTC).
