Looking for troubleshooting suggestions for a propane Yale, model GLC050VXNDAE083. Truck will randomly throw a code 92-1 on the display and the service engine fault light comes on. When this happens there is no response from the throttle. Normally, restarting the engine will correct the issue. This might happen once an hour or once a week. I am currently trying to find a parts/service manual for this truck, but we bought it used so I dont even have access to the menus. Does anyone have any suggestions on what I can check while I am waiting to find a manual. I appreciate it.

Ramon,
Start the engine and press the throttle pedal down and push on it sideways. If code shows, bushings inside pedal assy are worn and need replacing. You will need to install a new pedal and mount. Verify all connections and wiring has not chaffed. Good Luck
Hey gary did u ever figure out the problem. I have one with the same problem 91-2 so intermittent.
Thank you, the operator had the numbers reversed on the sign-out sheet. Is this a remove and replace procedure or will the new sensor need to be calibrated?
There is not a code 92-1, there is a 91-2 code. It sounds like your pedal position sensor is about to fail.
