Honda NX 125 Fault Codes
Honda NX 125 motorcycles have engines, which are made up of many different parts. These parts must work together in order for the engine to function. A problem with one of the parts can make the engine not run. There are many different parts that make up an engine. The following honda nx 125 faults are the list of some of the parts of a motorcycle engine.
What’s wrong with my Honda NX 125 motorcycle brake light and what can I do about it? There are a few possibilities. One is that your break switch is defective and will need to be replaced. Another is that your brake fluid level may be low.
Honda NX 125 Faults :
Your bike engine consists of a great deal of elements like the casting, cylinder heads and pistons. it's necessary to form certain these area unit all clean and lubricated to avoid engine issues. Conjointly keep in mind that Honda NX 125 motorbike engine could be a terribly delicate piece of machinery therefore it is best to handle it with care.

Honda MIL Failure Codes
The PGM-FI MIL denotes the failure codes (the number of blinks from 0 to 54). When the indicator lights for 1.3 seconds, it is equivalent to ten blinks. For example; a 1.3 second illumination and two blinks (0.5 second x 2) of the indicator equals 12 blinks. Follow code 12 troubleshooting.
When more than one failure occurs, the MIL shows the blinks in the order of lowest number to highest number. For example; if the indicator blinks once, then seven times, two failures have occurred. Follow codes 1 and 7 troubleshooting.
| Number of blinks | Causes | Symptoms | |
|---|---|---|---|
| 0 | No blinks | Faulty ECM | Engine does not start |
| 0 | No blinks | Faulty ECM (PGM-FI warning indicator output) | Engine operates normally |
| 0 | Stay lit | Short circuit in service check connector Faulty ECM (PGM-FI warning indicator output) | Engine operates normally |
| 1 | Blink | Open or short circuit in MAP sensor line (in the ECM) Faulty MAP sensor | Poor idle |
| 7 | Blinks | Loose or poor contact on ECT sensor Open or short circuit in ECT sensor wire Faulty ECT sensor | Hard starting at a low temperature (Simulate using numerical values; 90 C/194 F) Cooling fan does not stop |
| 8 | Blinks | Open or short circuit in TP sensor line (in the ECM) Faulty TP sensor | Poor engine response when operating the throttle quickly (Simulate using numerical values; throttle open 0) |
| 9 | Blinks | Open or short circuit in IAT sensor line (in the ECM) | Engine operates normally (Simulate using numerical values; 25 C/77 F) |
| 12 | Blinks | Loose or poor contact on injector connector Open or short circuit in injector wire Faulty injector | Engine does not start |
| 21 | Blinks | Loose or poor contact on O2 sensor Open or short circuit in O2 sensor wire Faulty O2 sensor | Engine operates normally |
| 54 | Blinks | Loose or poor contact on bank angle sensor connector Open circuit in bank angle sensor wire Faulty bank angle sensor | Engine starts but stops after few seconds. |

Issues with the engine are typically caused by issues with the engine parts. Whether it is a fuel issue or an ignition problem, the engine parts should be inspected to determine the cause. Another issue that can occur is when the Honda NX 125 motorcycle engine is not working is a failure of the electrical system. This can cause the motorcycle to stall and not work correctly. The electrical system is typically the most complex system on a motorcycle.

Honda Motor Company is by far the world's biggest motorcycle maker. Honda's first motorcycle was born out of necessity in immediate post World War II Japan, where public transportation was desperately overcrowded and gasoline severely restricted.Honda's first bikes were very successful and supplies of the surplus engines ran out after a few months. Business was good by then, so he decided to manufacture his own motors. Using the surplus motor as a model, Honda designed and built his own 50cc engine.

These abbreviations, and the accompanying list of trouble codes, can be a great start when your Honda check engine light comes on. As mentioned above, if you are not comfortable with electrical diagnostic work, a dealership or qualified technician can offer assistance. Please keep in mind that even though you have the ability to clear a DTC using the onboard diagnostic feature, you shouldn't clear the code prior to your service appointment. Let the technician view and clear the codes as they troubleshoot the issue.
