P02FE Cold Start Fuel Injection Control Circuit Range/Performance

EmissionsRelevant

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. P02FE means the circuit is electrically intact but the cold-start injection does not work as expected – for example a worn, sticking or partly clogged injector, contact resistance, or an empty auxiliary tank or faulty supply pump. Cold starts take longer or fail. No manufacturer document using this code was found; unlike the older P0213/P0214, these codes separate the fault types.

Likely causes

Cold-start injector or valve worn, sticking or partly clogged
Contact resistance at connector or ground
Cold-start fuel supply faulty (auxiliary tank empty, pump, filter)
Engine module or software

Symptoms

  • Check engine light on
  • Long or failed cold start
  • Rough running when cold
