P16Ab Fault Code: Understanding The Description And Troubleshooting Steps
The P16AB fault code refers to a problem with the intake air heater’s temperature sensor circuit. The intake air heater performs internal diagnostics for the temperature sensor circuit. If the voltage of the internal temperature sensor falls outside the calibrated threshold, the intake air heater sends a message to the Glow Plug Control Module (GPCM).
The GPCM then sends a message to the Engine Control Module (ECM) to set the appropriate Diagnostic Trouble Code (DTC). In this case, the P16AB code indicates that the intake air heater temperature sensor circuit has a high voltage.
FAQ
