P02FCCold Start Fuel Injection Control Circuit Low

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light

How the car detects it
Cold start fuel injection is an extra injection system for cold starts – for example on flex-fuel engines running on high ethanol blends, where a Hyundai patent describes a small auxiliary tank, a cold-start injector and a heater. CARB lists such heated fuel preparation systems among the monitored output components. P02FC means the control circuit reads low – typically the control wire shorted to ground or a shorted turn in the cold-start injector. Depending on the circuit the valve then does not work, or it stays open and over-fuels the engine, causing fuel smell and hot-start problems. No manufacturer document using this code was found; unlike the older P0213/P0214, these codes separate the fault types.
What you may notice
  • Check engine light on
  • Hard cold start, or over-fuelling with fuel smell if the valve stays open
  • Rough running when cold
Likely causes
  • LikelyControl wire chafed through, shorted to ground
  • PossibleShorted turn in the cold-start injector or valve
  • PossibleWater or corrosion in the connector
  • RareDriver stage in the engine module
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
