First off, this forum is great, looked up my problem in other posts & think I got it narrowed down to the speed sensor.
'course there's a story...
Have a 02 450 es, hit a tree, broke lower control arm, got her straight, looks great but noticed no speedo. Drove for about an hour & no es, light flashed 3 times. Thanks to this forum thought angle sensor, but with the speedo going first, thought speed sensor. Going take this weekend to fart around & check all connectors & clean 'em & charge battery.
Angle sensor seems pretty simple but no idea how to inspect speed sensor.
Any help is much appreciated!!
