What P02FD 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. P02FD means the control circuit reads high – typically the control wire shorted to a supply wire, or a bridged coil. The driver cannot switch the valve as commanded; cold starts become difficult. No manufacturer document using this code was found; unlike the older P0213/P0214, these codes separate the fault types.
P02FD at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P02FD
- Check engine light on
- Hard or no start in cold weather (especially with high ethanol)
Common causes of P02FD
- Most likelyControl wire shorted to a supply wire (chafed or pinched)
- PossibleShort in the cold-start injector or valve
- Less likelyMoisture or corrosion in the connector
- 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 P02FD 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). |
| FD | The exact fault in that area. |
What to do next
- Note P02FD 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 P02FD
What does P02FD mean?
P02FD means "Cold Start Fuel Injection Control Circuit High". 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 P02FD?
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 P02FD fail an emissions test?
Yes, it can. P02FD 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 P02FD to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P02FD clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
