Hello from Panama.
I live in the Country of Panama (Retired US Citizen). I?m new to this group this being my first Post. Before I continue with my question/problem. I have available a very long and detailed troubleshooting and part change/swap out document that detailing what I have done so far trying to solve this problem. I can either post or send it PM. Anyway here is my problem in smaller detail.
This problem started as an erratic and intermittent idle and then when degraded until I got the Check Engine light - that?s where the fun began. I hooked up the the YDIS and it showed both the TPS and the Air Temp Sensor codes. I was able to clear the codes and drive the boat and all was well for a few days although the idle was still erratic. I ordered parts and thus began the below TPS nightmare in Panama!
I changed ECM, TPS and Air Temp Sensor. The codes cleared, I test drove it twice and everything went great. I turned it in on and off numerous times. No problem it ran and performed great. The new day I went down and started it, bingo I got the Check Engine light?same codes. Now I can?t get the TPS Sensor (old one or new one) to adjust within limits when installed on the throttle body. I can however remove the TPS sensor and manually turn it approximately 10 - 15 deg past the maximum adjustment range (Screw Slots) and I can then clear the TPS code. It doesn?t matter if I use the Old or New ECM's or the Old or New TPS sensor etc.. I can now only clear the TPS code when the TPS is turned past the set limits using a slotted screw driver (TPS is plugged in but removed from the Throttle Body.
At this point I?m completely stumped.
What would of great benefit to me at this point would be If someone could send me to a link (document, manual, service bulletin, etc) where I can read and confirm whether I am installing the TPS sensor correctly onto the throttle body, or explain why I can?t set the TPS Sensor within the adjustment range. I am open for any guesses, suggestions on what to test,, retest, change parts, etc.
NOTE: I have the YDIS Software and cable and have been using it to trouble shoot the system. All of the Sensors check good (Voltage/Ohms) per the manual except the TPS Sensor. The Voltage, continuity and ohms checks have been performed per the Yamaha manual. The voltage at the TPS connector - between the Pink and Black wires is 0.00 and the voltage between the orange and black wire is also 0.00 One of the Yamaha manuals (on line - says check the Pink and Black and one Yamaha manual (mine) says to Check the Orange and Black wires at the connector. Continuity checks have been performed several times between the ECM wires/connectors and the TPS and Air Temp Sensors wires/connectors with great continuity every time!
Well I guess this one is long too?lol
Parts Changed to date.
ECM
TPS
ICS Valve
Air Temp Sensor
Battery Negative Cable - Temp Changed
Seroiusly any suggestions or wild ass guesses are welcome
Cheers,
