Bike: '09 FLHR
Two trouble codes:
- P2138 - Twist Grip Sensor Correlation Error
- P1510 - EFI Limited Performance Mode
On the TGS, I have put on new grips and recently there seems to be a very slight (and I mean very slight) stickiness from time to time. I was assuming I just needed to take it off and put some graphite lubricant in, but maybe it's the sensor going bad.
On the EFI, I've got a Power Commander on board, but it's been there for almost 20000 miles with no issues.
Any thoughts on how to further diagnose the problems?
