Yamaha F115, TPS voltage ?

[loyoki]

Hi,
I have idle problem on my F115, RPM (800,900) at neutral.
I would like to adjust TPS but I don't know voltage I have to read ?
As I saw in another post, it seems to be between pink and red wires ?
Many thanks

My book says Pink and Black. V=0.732 + or minus .014v. This is from the f115tlrb 2003 manual.

Thats between pink and black on the motor side of the harness. It is pink/red on the sensor side.

OK, many thanks, sorry I made a mistake there is only 3 wires (black, pink, orange) and you are right, it is between pink and black but it is very difficult to adjust, very sensitive. I done the job, when started engine, idle was at 800/900 RPM but when hot, and started it again, idle remains normal (600/700 RPM).
Many thanks

This spring my F115 would idle (in neutral) at 7-900 with a slight fluctuation regardless of whether it was cold or warm and not at 600.

After advice from Rodbolt and others, we found it was the thermostat. It was not closing completely. Pull yours and test it. It should be changed every 2-3 years.

See this thread

Hope this helps.

I change thermostat 5 months ago but I will check it again.
Thanks
