Fuel Injector Injection Amount Correction

NOTE:
  • The fuel injection amount correction can be performed when all the following conditions are met. The implementation conditions for the fuel injection amount correction can be met by warming up the engine completely.

    Implementation conditions for fuel injector injection amount correction

    • ECT:70-95°C {158-203°F}(Altitude:approx. 1, 000 m {3, 281 ft} or less)
    • ECT:80-95°C {176-203°F}(Altitude:approx. 1, 000 m {3, 281 ft} or more)
    • IAT:0-65°C {32-149°F}
    • Fuel temperature:20-80°C {68-176°F}
  • If fuel injector injection amount correction is not completed, the check engine light and glow indicator light illuminate. In addition, the PCM stores DTCs P1200:00 and P167B:00 (cleared by completing fuel injector injection amount correction).
  • If only P167B:00 is stored, the glow indicator light flashes.
  • If the fuel injection amount learning fails, switch the ignition off, wait for 15 s or more, then perform the procedure again.
  1. Maintain the engine speed at 2, 500-3, 000 RPM and warm up the engine completely.
