Spot on! Took me forever to figure out what was happening when G22 failed (7 years ago)...?
Vehicle goes into Limp Mode because of erratic data off G22 doers not correlate to Tranny speed G68...? Can't accelerate...
Pull to the side of the road and one can accelerate the engine normally...
Speedometer bouncing erratically...
A good way to test if this issue is to disconnect G22, and drive. Problem goes away...
Also a good way to drive around if you can't get G22 right away and need to use the vehicle...
Of course, no speedometer reading, but some times ya gotta do what ya gotta do!
