Started the coach today and shifted into gear. Didn't shift and steady beep sounded. The error code displayed is:
D1-21-12 which is "Throttle Position Sensor failed low." After starting it a couple of times, it shifted fine. No other codes are displayed.
I cleared the code and it did not reappear at startup.
This rig has the King Control so I believe the throttle position sensor is internal to that unit. Anyhow, anyone know anything about this? Thanks.

If you haven't already scroll down to the bottom of the link to throttle Diagnostics, click on that more charts come up. Looks like there's some checks you can make for the throttle position sensor.

Just printed that out. We're going to leave in the morning so I'm hoping it does not reoccur. Thanks. I suppose I should start thinking about an air throttle or hydraulic or whatever.
