Yamaha Fault Codes

This Yamaha manual provides the information required for normal servicing.

In the list range from d01 to d59, a self-diagnosis of the system components is carried out.

Inclusion of some components is carried out by the stop engine button.

Yamaha Self-diagnosis Code List (opposite the menu number of the list, decoding of readings + nominal value):

D: 01 = Throttle Position Sensor completely closed, indicators from 12 to 21 fully open, indicators from 96 to 106
D: 02 = atmospheric pressure, in percent;
D: 03 = absolute atmospheric pressure in the intake circuit;
D: 05 = air temperature in the intake circuit;
D: 06 = coolant temperature;
D: 07 = speed sensor readings;
D: 08 = drop sensor position normal position, indicator 0.4 - 1.4 inverted position, indicator 3,7 - 4,4
D: 09 = vehicle voltage
D: 13 = Throttle Position Sensor 2 completely. closed, indicator from 9 to 23 fully open, score from 94 to 108
D: 14 = Throttle Position Sensor 1 completely closed, indicator from 12 to 22 fully open, indicator from 97 to 107
D: 15 = throttle position sensor 2 completely closed, indicator from 10 to 24 fully open, indicator from 95 to 109
D: 20 = position sensor side steps;

These abbreviations, and the accompanying list of trouble codes, can be a great start when your Yamaha 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.
