Author Message   Brokeneck Posted on Sunday, April 03, 2011 - 03:53 pm:        It's propably just a ooincidence -- but the speedo on my 2000 S3 went out -- first time I tried to ride at exteneded highway speeds the bike barely runs -- last time it did this it was a temp sensor -- but since it runs great around town I was wondering if the EFI uses the speedo for operating info?   Hybridmomentspass Posted on Sunday, April 03, 2011 - 05:57 pm:        no I dont even have a speedo on my bike (drag bike), and it made zero difference to the running of the bike   Ratbuell Posted on Sunday, April 03, 2011 - 09:34 pm:        But if your speed sensor went out, THAT can absolutely have an effect. Is it dead gauge? Or dead sender?   Hootowl Posted on Monday, April 04, 2011 - 09:58 am:        Unplug the sensor and see if your rough running condition goes away.   Kyrocket Posted on Monday, April 04, 2011 - 10:12 am:        It might be an intermittent problem but if the sensor goes completely out the bike won't even start. And you will spend hours upon hours tracing wire. Been there, done that.   Natexlh1000 Posted on Monday, April 04, 2011 - 11:24 am:        Doesn't that sensor run off of a 5V output of the ECU? If the sensor is proper F*$KED, perhaps it's dragging on the ECU? I agree with the above, just unhook it and tape the connector. See if it does anything at all different.

That didn't start until the XB12 in 04. It NEEDS a 5 volt regulated power source, but it is getting battery voltage. The replacement sensors have a regulator built in. The regulator solved the speed sensor issues that plagued the 1999-2003 tubers. I believe our very own Reepicheep had a lot to do with the cure.   Brokeneck Posted on Monday, April 04, 2011 - 10:52 pm:        So from previous experience I'm assuming it is the speed sensor causing the speedo problem -- if so the consensus is that this could be the problem?   Hootowl Posted on Tuesday, April 05, 2011 - 09:38 am:        I'll bet you a dollar that if your speedo isn't working, it is the speed sensor. It could be something else, but it isn't very likely. Make sure you get the correct updated part. I'd just order it from American Sport Bike. You're guaranteed to get the right one. http://www.americansportbike.com/shoponline/ccp0-p rodshow/17165.html
