  • Information Motor Yamaha FS115 2004

    I have a motor Yamaha FS 115, 2004
    Model F115AET
    Serial: 68V L 1125211
    Letter: C
    Problem: When I accelerated the engine fails for a short time, then goes away and works normal, the fault is current, has been scanning the computer and does not reflect problems, clocks mark these numbers or codes: 31 and 32 . I tried to find information on this model and can not find anything if you know where I can download some information thank you. The boat with yamaha engine is used for commercial fishing. I am a marine mechanic and this was the first engine that has given me so many headaches I've repaired and fixed, I have the YDS Diagnostic and reflects me error, it could be that at the time the fault does not occur. But according to my knowledge and experience with other engines will adjudge the TPS problem, I need a helping hand to this issue, any help will thank you.

    use the active test.
    test the ISC.
    TPS failures and rare.
    TPS is easy to monitor.
    the ECU does NOT monitor ISC.
    the ECU sends a request to the ISC and assumes it happened.
