Why does the TPS have to be reset on XBs? What does it do? What happens if it is not set correctly? Is there any harm in riding the bike with the TPS not set correctly? And finally: Why, oh why didn't Buell make the TPS "user servicable"? | ||

It's Throttle Position Sensor. It tells the fuel injection where zero is. So after the ECM knows zero, it knows all other positions as well. I think that answers your other questions as well. Except the last one. It is now serviceable with the help of Direct Link and a Scan tool available from American-Sportbike. | ||

But why don't other fuel injected bikes (Honda's etc) have to have their TPS reset at regular services? | ||

I wouldn't know. This is the first bike I've owned with fuel injection. I had my TPS and timing done at 20,000 miles, and kind of forgot about it. I just hit 45,000 miles and thought I might out to have it checked again. Once the service guy was finished, he asked me if I was noticing any problems, I said "No, why do you ask" he said when someone comes in for a reset it usually meant they were having some sort of difficulty. I asked him what he found wrong, he said nothing at all was wrong, and the ECM looked like it should. Everything was right on. I think maybe Buell just wants you and the service team to be aware with what's going on with your bike. If you go in regularly to have it looked at, it's being looked at regularly. That's a good thing. |
