| Fault code No. | 14 |
| Symptom | The intake air pressure sensor has failed (due to clogging of hose or sensor disconnection). |
| Fail-safe action | Engine startup: Possible |
| Riding: Possible | |
| Diagnostic monitoring code No. | D:03 |
| Meter display | Displays the intake air pressure. |
| Checking method | Set the engine stop switch to " ", and then push the start switch " ". (If the display value changes, the performance is OK.) |
| Item/components and probable cause | Check or maintenance job | Sensor inspection procedure | |
| 1 | The intake air pressure sensor hose is damaged, disconnected, clogged, twisted or bent. | Repair or replace the sensor hose. | Starting the engine and operating it at idle. Fully close the throttle and check the fault recovery. |
| 2 | Intake air pressure sensor malfunction | Check in the diagnostic mode (Code No. 03). When engine is stopped: Atmospheric pressure at the current altitude and weather conditions is indicated. 0 m above sea level: Approx. 101 kPa 1000 m above sea level: Approx. 90 kPa 2000 m above sea level: Approx. 80 kPa 3000 m above sea level: Approx. 70 kPa When engine is cranking: Make sure that the indication value changes. The value does not change when engine is cranking. → Replace the intake air pressure sensor. Sensor inspection procedure. Refer to "Checking the intake air pressure sensor". | |
| 3 | ECU malfunction | Replace the ECU. |
