Hyundai/Kia FPR Replacement
Supported coding features by HiCOM diagnostic tool https://www.obdtester.com/hicom
What it does
- Resets ECU adaptation for fuel pressure control
- Ensures correct fuel rail pressure and injector performance
- Restores optimal engine operation and efficiency
When it is required
- After replacing the fuel pressure regulator or pump
- After fuel system repairs affecting pressure
- When fuel pressure-related fault codes appear
- When abnormal fuel delivery or engine performance is observed
Conditions that must be met
- New FPR / pump properly installed and connected
- Fuel system free of leaks
- No active fuel pressure or engine fault codes
- Ignition ON, engine OFF (unless instructed)
- Stable battery voltage
What happens during the procedure
- ECU clears old fuel pressure adaptation values
- Measures baseline fuel rail pressure
- Stores new reference for:
- Injector timing
- Fuel delivery quantity
- Fuel system response
- Monitors system for proper operation
If procedure is not performed
- Incorrect fuel pressure regulation
- Engine may run rough or hesitate
- Fault codes may remain active
- Potential fuel system damage or limp mode
After replacement
- Verify fuel rail pressure in live data
- Perform a short test drive
- Monitor engine performance under load
- Confirm no fuel system warnings remain
