auto tranny speed sensors

[suprra_girl]

so... mums car has been fighting with code 61 for donkeys now... i have finally fixed it

has yellow plug 7mgte ecu/front engine bay loom/dash loom (was a ga70)
has an original 7mgte auto transmission non abs (mums car was also non abs)

plug it all up.... o/d light flashes grrr

change trannies due to other reasons, still does it
change speed sensor with another.... still does it

original 1g transmission didn't do it

ok... go and look at the difference between the two... oh... the 1g transmission has a 1 wire speed sensor the 7m has a 2 wire

swap in 1 wire sensor = ALL GOOD!!! yay finally lol

so my question is...

what is the 1 wire sensor for
what is the 2 wire sensor for
and i presume the 3 wire is abs... so what is the difference between the other two?

so, i guess no one knows about auto speed sensors huh!

but anyway...

i highly suggest repairing any codes for your tranny, especially code 61

we have gone from 15mpg to 25mpg woot! and still no sign of that damned code 61


edit: messed up the conversion... 25mpg not 41 hehe i was still in litres
