What P02FB means
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.
P02FB at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P02FB
- Check engine light on
- Hard or no start in cold weather (especially with high ethanol)
- Rough running right after a cold start
Common causes of P02FB
- Most likelyCoil of the cold-start injector or valve open
- PossibleConnector loose, corroded or pin pushed back
- PossibleBroken wire in the harness
- Less likelyFuse or relay of the cold-start system
- Less likelyDriver stage in the engine module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P02FB means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2 | Area: fuel and air metering (injector circuit). |
| FB | The exact fault in that area. |
What to do next
- Note P02FB and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P02FB
What does P02FB mean?
P02FB means "Cold Start Fuel Injection Control Circuit/Open". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P02FB?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P02FB fail an emissions test?
Yes, it can. P02FB is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P02FB to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P02FB clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
