You fix one thing, 2 things break! After a lot of progress on the 1991 Land Rover Range Rover classic, we had the check engine light turn on. The code was showing error code 48, which is related to the stepper motor. The Rover was idling fine, running fine, and no other issues. Even after I would reset it, it would come back right when we turned the Rover on. I elected to replace the stepper motor, as my first step. Below I outline, in a video, the process to replace the stepper motor. It’s easy!
