MT07 Yamaha fault code list dash

I decided to do a quick chart of all of the Yamaha fault code list 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 2014-2021 Yamaha FZ, MT, Tracer, & XSR700 motorcycles.

OBD2 Fault code reader

OBD2 Fault code reader for Yamaha motorcycle

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 DisplayTesting Procedure to repair.
1Throttle position
sensor
Check with the fully open and fully closed position
3Intake air pressureDisplays the intake air pressure.
5Intake air
temperature
Check the air temperature with the scanner tool
6Coolant temperatureCheck when cold that the coolant temperature
is the same as ambient air temp
7Rear-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.
8Lean 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.
9Fuel System voltageShould be between 12-13.4 volts. Charge the battery and test again.
20Sidstand switch up

Stand retracted ON
Stand extended OFF.
Test with the transmission in gear.
21Gear position and

Transmission is in neutral ON
Transmission is in gear or the clutch leaver released OFF
Transmission in gear with the clutch lever pulled in and the
side stand extended ON
Transmission in gear with the clutch lever pulled in and the

60EEPROM 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.
67ICS

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.

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

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.

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.
