DTC DESCRIPTION P226C - TURBOCHARGER BOOST CONTROL A SLOW RESPONSE

Description:  This DTC sets when the difference between the actual Manifold Absolute Pressure (MAP) value and the desired MAP value is greater than a calibrated threshold when the monitor runs.
Possible Causes: 
  • Turbocharger actuator is not responding
  • Damaged MAP sensor
  • Air Induction leak
Diagnostic Aids:  The presence of this DTC may indicate that the vehicle is operating in derate mode and may experience a loss of power. After repair, the vehicle may still display a system warning message. Drive the vehicle until the system warning message has cleared from the instrument cluster message center. A concern is indicated if the MAP value does not change by a calibrated value in a calibrated amount of time during the completion of the monitor.
