Honda Super Cub Fault Codes
Honda Super Cub 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 super cub faults are the list of some of the parts of a motorcycle engine.
The fault codes are essential to the Honda Super Cub motorcycle operation, as they create the spark that ignites the mixture of air and fuel in the engine. Check to see that the spark plugs are not soiled with carbon. As a result, the spark plugs will provide a much weaker spark. The most common cause of soiled spark plugs is the improper installation of an air filter. The air filter prevents dirt from getting into the engine, but a faulty air filter will allow dirt to enter the carburetor.
Honda Super Cub Faults :
The warning light comes on when one of the various sensors has detected an abnormal condition in the Honda Super Cub engine's performance. For example, if the oil pressure drops below a certain threshold or if the air/fuel ratio rises beyond a certain point, then this would cause an immediate alert from your vehicle's engine management system.

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 |

Fault problems that can occur with yourHonda Super Cubmotorcycle engine is a blown head gasket. This can cause your engine to overheat and possibly crack the cylinder heads. In this case, it is best to take your Honda Super Cub motorcycle to a professional mechanic to have it checked out. Another common problem is with the carburetor. The carburetor is the part of your motorcycle that mixes air and fuel to create the combustion needed to power the engine.

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.
