Error code 21 is popping up. I think i need to replace this component. Does anyone have a spare one of these. The only one I can find is over $100. If you think the error code 21 is something else please let me know.

Well - code 21 could be a couple of things.

If you think its the PTU (Power Transistor Unit) here is a how-to to use a newer, upgraded PRW-2 unit.

If you think the issue is a faulty Crank Angle Sensor, they are available here -
