Yamaha Motor Co., Ltd. YFM7FGPW — FUEL INJECTION SYSTEM

Sensor operation table 6 - 11 FUEL INJECTION SYSTEM FI FI Diagnos- tic code No. Item Meter display Checking method D01 Throttle angle • Fully closed position • Fully opened position 15 ~ 20 95 ~ 100 Check with throttle fully closed. Check with throttle fully open. D03 Pressure difference (atmospheric pressure and intake air pressure) Displays the intake air pressure. Set the engine stop switch to “RUN”, then operate the throttle while push- ing the start switch. (If the display value changes, the performance is OK.) D05 Intake air temperature Displays the intake air temperature. Compare the actually measured intake air temperature with the meter.

D06 Coolant temperature Displays the coolant temperature. Compare the actually measured cool- ant temperature with the meter. D07 Vehicle speed pulse 0 ~ 999 Check that the number increases when the rear wheel is rotated. The number is cumulative and does not reset each time the wheel is stopped. D08 Lean angle sensor • Upright • Overturned 3.7 ~ 4.4 0.4 ~ 1.4 Remove the lean angle sensor and incline it more than 65 degrees. D09 Fuel system voltage (battery voltage) Approximately 12.0 Set the engine stop switch to “RUN”, and then compare with the actually measured battery voltage.

(If the bat- tery voltage is lower, perform recharg- ing.) D21 Neutral switch • Neutral • In gear ON OFF Shift the transmission. D60 EEPROM fault code dis- play • No history • History exists 00 01 — D61 Malfunction history code display • No history • History exists 00 Fault codes 12-50 • (If more than one code number is detected, the display alternates every two seconds to show all the detected code numbers. When all code num- bers are shown, the display repeats the same pro- cess.) — D62 Malfunction history code erasure • No history • History exists 0 Up to 16 fault codes — To erase the history, set the engine stop switch to “OFF” and then to “RUN”. D70 Control number 00 ~ 255 —
