  • 2002 Yamaha check engine light on, self-diagnosis, how to read code, and code list

    I have a 2002 Yamaha FX140 / FX1000A and my check engine light came on and I figured out how to read the code on the jet ski.
    Hold down both of the buttons on the multifunction meter for 8 seconds while the engine is running and the code will be displayed on the multifunction meter.
    In the service manual for 2004-2007 FX 1100/1100A it states with the engine running, press the select button for 8 seconds and check if an error code is indicated on the multifunction meter.
    • code / symptom
    • 01 / normal
    • 13 / pickup coil malfunction\
    • 15 / engine temperature sensor malfunction
    • 18 / throttle position sensor malfunction
    • 19 / incorrect battery voltage
    • 23 / intake air temperature sensor malfunction

    • 54 / bypass valve motor malfunction
    • 55 / steering switch malfunction

    I hope this will help someone.
