P0299 on Dodge vehicles indicates turbo/supercharger underboost condition. Au7o has documented this code across 1 Dodge model — most commonly on Neon. P0299 means the engine computer detected an underboost condition — the turbocharger or supercharger is producing less boost pressure than the PCM expects for the given conditions. The computer compares the manifold/boost pressure sensor reading to a target based on engine load, and when actual boost falls short, it sets this code. The most common real-world cause is a leak somewhere in the intake/charge-air path. You'll typically feel reduced power or sluggish acceleration, and the engine may go into a reduced-power mode. Typical repair costs on Dodge range from $800 to $2,500, depending on the specific model and root cause.

Common Causes of P0299

  • •Boost/intake leak (cracked or loose charge-air hose or intercooler)
  • •Faulty or sticking turbo wastegate or actuator
  • •Stuck or clogged variable-geometry turbo vanes (VGT)
  • •Faulty boost pressure or MAP sensor
  • •Leaking or disconnected vacuum/boost control lines
  • •Restricted air intake or clogged air filter
  • •Failed boost control solenoid
  • •Worn or failing turbocharger

  • SRT-4 Turbo Oil Feed Line Restriction2003-2005

    The turbo oil feed line develops restrictions causing oil starvation and turbo bearing failure. Turbo failure can occur well before 100,000 miles. Oil starvation is the primary cause of premature turbo failure on SRT-4 models.
