Hey guys, first year with fuel injected harley-

That being said I think my TPS has started to act up. It feels like it lost its zero reference.

When sprung into zero it idles high, but can be idled down when the throttle is twisted forward (so I don't suspect iac or o2 sensor). It also has some popping when decelerating since I bought it this spring.

Any suggestions?

I've tried twisting from -10 to full throttle when off, key on, and riding down road. Started and stopped 3-4 times since it started.

Thanks Guys

Jake

 

To reset the high idle..

Warm up bike. Shut it down. With Run switch in RUN position turn on the console switch. Count to 10. Turn console switch off.

Repeat that three times.

The TPS will relearn idle.

Always turn off the bike at the console switch then run switch to prevent bumping the throttle at shut down which causes high idle issues.


Your popping is probably a different issue. If your idle doesn't reset after the above then the two are related and you need to speak with a tech.

 

Idles back down after warm up now, thanks wiz
