P0299

Technical Definition:

Turbocharger / Supercharger Underboost

Trouble Code: P0299
Address: 0x0299
System: Powertrain
Subsystem: Fuel and Air Metering
Technical Description:

The DTC code refers to a condition where the PCM/ECM (powertrain/engine control module) has detected that the bank “A” or single turbocharger or supercharger is not providing a normal amount of boost.

Possible Causes:
  • Intake (induction) air restriction or leak
  • Failed or damaged turbocharger (sticking, binding, etc.)
  • Faulty boost/charge pressure sensor
  • Faulty wastegate bypass regulator valve (VW)
  • Low fuel pressure condition (Isuzu)
  • Sticking turbo nozzle control solenoid (Isuzu)
  • Faulty injector control pressure (ICP) sensor (Ford)
  • Low oil pressure (Ford)
  • EGR system fault (Ford)
  • Variable geometry turbocharger (VGT) actuator (Ford)
  • VGT vanes sticking (Ford)

Possible Symptoms:
  • MIL (Malfunction indicator lamp) illumination
  • Reduced power output from engine, possibly in a limp mode
  • Unusual sounds from the engine/turbo
