Full Yamaha Fault Code List to Help With Troubleshooting Your Motorcycle.

I decided to do a quick chart of all of the Yamaha fault code lists that I have come across as a mechanic. There are literally hundreds of fault codes so it will be an ever-growing list as I dig them out of my MT-07 service manual.

This will cover all self-diagnosis fault codes for 2014-2023 Yamaha FZ, MT, Tracer, & XSR700 motorcycles plus many others.

Yamaha Fault Code List

Following error codes DO NOT allow the engine to run :
 
11-12-19-30-41-50 and Error-1 to Error-4
 
Error code 11 allows the engine to continue running only if a fault appears after the engine starts. So if you get a check engine light Yamaha fault code list is helpful.

OBD2 Fault code reader

You can use an OBD2 fault code reader to check the conditions of your Yamaha Motorcycle. The ECU will record and display real-time and stored fault codes that you can read on the OBD2 port.

You will need to have the Yamaha motorcycle turned on and running to test certain live fault conditions. If you are able to start the motorcycle turn the key to AUX and read the fault codes.

Check out how I connect a Bluetooth OBD2 scanner using a Yamaha 4-pin cable to my MT07 to clear and read faults.

Check engine light but no code

In this case, you will need an OBD2 scanner to connect up to see if there are any saved error codes in the memory of the ECU EEPROM. From here you may find a Diagnostic code number stored. Use the list below to see what event has caused an error fault.

Diagnostic Code Number	Tool Display	Testing Procedure to repair.
1	Throttle position sensor	Check with the fully open and fully closed position
3	Intake air pressure	Displays the intake air pressure.
5	Intake air temperature	Check the air temperature with the scanner tool
6	Coolant temperature	Check when cold that the coolant temperature is the same as ambient air temp
7	Rear-wheel vehicle speed pulses	0-999 Check that the pulses increase when the rear wheel rotates. The number increases with each rotation of the wheel. It is cumulative and does not reset each time the wheel stops.
8	Lean angle sensor. Upright and overturned.	Upright 0.4-1.4 volts Overturned 3.7-4.4 volts. To test remove the lean angle sensor and tilt greater than 65 deg.
9	Transmission is in neutral ON Transmission is in gear or the clutch leaver released OFF The transmission in gear with the clutch lever pulled in and the side stand extended ON The transmission in gear with the clutch lever pulled in and the side stand retracted OFF	Should be between 12-13.4 volts. Charge the battery and test again.
20	Sidstand switch up down	Stand retracted ON Stand extended OFF. Test with the transmission in gear.
21	Gear position and clutch switch	Transmission is in neutral ON Transmission is in gear or the clutch leaver released OFF The transmission in gear with the clutch lever pulled in and the side stand extended ON The transmission in gear with the clutch lever pulled in and the side stand retracted OFF
60	EEPROM fault code display	No history the EEPROM is defective and needs to be replaced. The diagnostic tool may show code 00. Fault code P062F may also show on the dash with error writing/reading from the EEPROM.
67	ICS Idle speed control	00 Learning data ICS has been erased. 01 It is not necessary to delete the ICS data. 02 It is necessary to delete the ICS data. To erase the ICS move the start/engine run switch between run and stop 3 times within 5 seconds.
70	Control Number	0-254
87	O2 feedback Learning Data	00 O2 feedback learning data has been erased 01 O2 feedback learning data has not been erased. To erase the ICS move the start/engine run switch between run and stop 3 times within 5 seconds.

Yamaha MT07 wiring diagram

To help with the Yamaha fault code list I have included my wiring diagram for the MT07. I do recommend getting yourself a Yamaha MT07, Tracer, & XSR700 service manual to help you do everything from DIY services, tune-ups, repairs, and fault finding.

10 Reasons why your Motorcycle won’t start – no fault code.

Check out the video below on why your motorcycle won’t start with a good battery. Often you won’t have any fault codes.

Conclusion

Hopefully, the above Yamaha Fault code list will help you diagnose faults with your motorcycle. If you come across any extra fault codes let me know in the comments below and I will add them to the current list.

As newer models come into the market they become smarter and have extra codes added to help fix the problem.

I just wish they would use basic English for example Yamaha error code 46 is the charging voltage is abnormal. It really means a flat battery.

Now fix your motorcycle and do a quick MT07 oil change service and maybe I will see you out on the road one day. If all else fails check out these funny motorcycle quotes and sayings to brighten your day.
