P02FBCold Start Fuel Injection Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- 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. P02FB means the control circuit of the cold-start injection is open or has a general fault – a broken coil, a loose or corroded connector or a broken wire. The engine then starts poorly or not at all in the cold; once warm it runs normally. 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 or no start in cold weather (especially with high ethanol)
- Rough running right after a cold start
- Likely causes
- LikelyCoil of the cold-start injector or valve open
- PossibleConnector loose, corroded or pin pushed back
- PossibleBroken wire in the harness
- RareFuse or relay of the cold-start system
- 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.
