Riding this w-end & every time at idle this code P0122-TPS Circuit Low with little engine icon pops on screen??
Seems to run just fine, but worried about getting way back in back country & having it fail!!
If I remove the box should I try cleaning it, if possible, or just go ahead & replace it @ $150.00
Doesn't seem to be a common problem? I haven't seen any posts with this kind of problem.

Think it's fixed, ran for 20 mins with no codes.
Diagnostic said 127%, so adjust TPS sensor about a million of an inch back to zero & that seemed to fix it.
I suspect over a period of time the throttle plate may be closing ever so slightly more & putting TPS out of whack!
Cleaned the dirty air sensor while I was at it, always seems to be a lot of dirt getting by the filter!?
