Fixing diagnostic faults (how?)
My 93 E420 has the following indicated faults which I found out using the diagnostic LED:
6 blinks: idle speed control inoperative.
Is there a part I should replace here? My idle sometimes fluctuates slightly, but most of the time its fine.
25 blinks: Knock sensor
Where is the knock sensor located? How do I know if I should already replace it?
26 blinks: upshift delay switch over valve (SOV) open/shorted
What does this mean?
Thanks.
