Hi Guys and Girls,
I hoping someone here can offer some advice. I have a 2001 single spark R1150 GS. Recently it has started to intermittently have a rough idle when warmed up. More worryingly it also loses all power under hard acceleration, it totally bogs down.
I scanned for codes and the only one present is error code 288 : throttle position sensor, internal fault on upper or lower potentiometer slider.
When I try to calibrate the TPS on GS 911, I get an error saying idle switch should be in the off position.
The fast idle switch is off, I can see that the throttle cables have free play and that they are hitting their stops.
I have tried adjusting the TPS manually to get the idle switch to register the off position, even at zero degrees it still registers open.
I am wondering if anyone knows whether this error code could be caused by a faulty TPS?
They are expensive and I can't really afford a new one that may not solve the issue.
If anyone has had a similar issue I would appreciate and insights/advice.
Thanks in advance,
Tom.
